Introduction to Disc Springs
Disc Springs, also known as Belleville Washers and
Belleville Springs, are discs with a slight cone shape, that
deform to a shorter height when subjected to a load along
their axis of symmetry. This elastic deformation
characterizes the spring action.
MW Industries’ disc spring fabrication is subject to exacting
manufacturing and quality control standards. Materials
used are generally in the annealed condition and hardened
to within a range of Rc 44-51 depending on the material
thickness. When required, disc springs are preset so that
they will not significantly relax under load over time.
Disc springs can be a good design solution where the load
required is high and the space available is limited. They
can be tailored to provide loading profiles that are not
feasible with coiled springs. Disc springs are used singly or
in stacks to achieve a desired load and travel. Our disc
springs are commonly used in high temperature/extreme
pressure applications, pipe flange applications, bolted joint
applications, heavy and light bolting applications, dynamic
applications and bearing preloaded washer applications.

Theoretical vs. Measured
Characteristic of a Disc Spring
The shape of Belleville disc springs make accurately
predicting their performance a challenge. The design
information that follows offers good results for most parts
that fit within the following parameters:
can be used to optimize a spring system for special
applications. When this ratio of h/t is small (up to 0.4) then
the shape approximates a straight line. Several examples of
shapes for specific values of h/t are shown below.
GRAPH FOR CDM-502520
(50 mm x 25.4 x 2.0 x 3.4 OH)
Ratio of diameters = OD/ID between 1.75 and 2.5
Ratio of cone height to thickness = h/t between 0.4 and 1.3
Ratio of diameter to thickness = D/t between 16 and 40

MEASURED CHARACTERISTIC
Belleville disc springs should be designed to work within
the range of 20% to 80% of their total available deflection
to avoid premature fatigue failure. For applications that
require springs to operate outside of these parameters,
please consult our disc spring design team.

Engineering & Design Information
The load deflection formula was developed by J. Almen
and A. Laszlo, and published in the Transactions of the
American Society of Mechanical Engineers, May 1936, and
is rendered as follows:
Typically, the overall height of the disc spring is specified
because it is easy to measure and control. The cone height
(h), on the other hand, is difficult to measure (see Figure 4).
t
Load in pounds at a given deflection:
Y
Figure 4
OH
H
β
Disc Spring at Flat
In the flattened condition, the deflection (f) is equal to the
conical height (h) and the equation becomes:
For an approximate calculation, (h = overall height – t)
is acceptable. However, this is not accurate. In fact,
h = (overall height – Y), where Y = Cos β • t. For small
thicknesses (under 2 mm), this is not significant. With
thicker disc springs, this becomes a major factor for
accurate load and stress calculations. This has not been
adequately considered in previous technical literature.
To calculate the load accurately, the following important
factors must be considered:
P
Flat
OD
Figure 2a
Figure 2b
β
R
R
If the disc spring is made as in Figure 2a, with edges
machined to be parallel to the springs central axis, then
R = OD/2. Most disc springs are made as in Figure 2b.
Therefore, the load-bearing radius is not equal to half of
the maximum outside diameter. To calculate R, the angle β
first has to be determined.
A well-designed disc spring has radii at all corners to
reduce stress concentrations at the edges. A suitable radius
is approximately = t/6. This radius further reduces
dimension R (see Figure 3).

Figure 5
Disc springs that are 8 mm and thicker are made with a
bearing flat at upper ID and lower OD as standard (see
Figure 5). This bearing flat assures more uniform loading
and better alignment of the disc spring stack. The flat is
equal to approximately OD/150. For load calculations, R
must be calculated to the inner edge of the flat.
Summary
Precise load and stress calculations require the
determination of the disc spring angle (β). Since this is not
easily determined by physical measurement, we have
developed a computer program that calculates the precise
angle and arrives at the exact dimension for conical height
(h). This exact dimension then determines accurate load
and stress calculation. When designing custom disc springs,

Engineering & Design Information
The load and stress formulas are correct only with the
assumption that the spring will be worked within the elastic
limit of the material.
Dynamic Loading & Fatigue Life
Fatigue life for disc springs is defined by the effective
number of stress cycles that can be sustained under certain
conditions, prior to failure. This depends on the minimum
stress, maximum stress, and stress range.
The fatigue life for a particular Belleville disc spring design
can be predicted by making the assumption that its load
fluctuates smoothly over time from preload to final load
(dynamic loading). This however, is not true in cases of
impact loading and therefore, it is difficult to predict life
and behavior when springs are impact loaded.
Disc spring fatigue life may be differentiated into two
categories:
1) Limited life: cycles without failure, between 40,000
and 2,000,000 cycles.
2) Unlimited life: cycles in excess of 2,000,000 cycles
without failure.
The table below can be used to guide design of Belleville
disc springs for “unlimited life”.

The diagrams presented here are for forecasting fatigue life
of single disc springs or series stacks of no more than six
disc springs. There are three groups, based on thickness
(see legend with each diagram). The horizontal axis
represents “preload stress”. The vertical axis represents
“final stress”.
The fatigue life is found at the intersection of these points
on the graph. The “zone” in which they fall tells the
predicted life. If they fall outside the zones, their life is
generally not predictable.
6
The horizontal borderline enclosing the top portion of the
graph zone represents the yield strength of the spring steel
material.
Intersection points of minimum/maximum stress limits
which fall outside the graph zone boundaries are to be
avoided as they indicate spring failure will be likely at an
early stage.
The graphs were developed based on empirical test data.
How to use the graphs:
1) For standard catalog disc springs:
a) Determine the preload stress
b) Determine the final load stress
The intersection of the stress coordinates will indicate the
range of fatigue life that may be expected.
2) For non-standard or custom disc springs:
a) Determine the preload stress from the formula on
page 7 for points S2 and S3. Use the HIGHER of the
two values for preload and final load.
b) Repeat above procedure for the “final stress” again,
using the higher value found.
Example using Series CDM Disc Spring:
CDM-188207: .709 x .323 x .0276 (see page 14)
Preload stress at deflection f = .5h : 124,000 psi
Final load stress at deflection f = .75h : 174,000 psi
Intersection point between nearby 2 x 104 cycles and
5 x 104 cycles
Predicted cycles: 20,000 cycles

For evaluation of compressive stress, use formula S1.
It computes the compressive stress at the upper inner
diameter. This compressive stress may be as high as
400,000 psi for certain bolted applications.
For dynamic applications, it is necessary to consider the
tensile stresses at the points marked S2 and S3. The
stresses at these points depend on the ratio of diameters
(α) and the spring characteristic (C) as well as on the
deflection (f). This stress should not exceed 200,000 psi
at .75h deflection.

Disc Spring Damping (Hysteresis)
In disc spring stacks, particularly those with parallel units,
friction must be considered. Sliding friction occurs at the
disc spring’s adjoining, moving surfaces (radial walls). As a
result, the spring force increases on loading and decreases
on unloading, causing a damping effect (hysteresis). This
characteristic may be taken advantage of in shock loaded
or vibrating systems that need damping. The hysteresis
effect is a function of the number of disc springs in parallel.

2. Clamp load is also known as preload or initial load in tension on
bolt. Clamp load (lb.) is calculated by arbitrarily assuming the usable
bolt strength is 75% of the bolt proof load (psi) multiplied by the stress
area (sq. in.) of threaded section of each bolt size. Higher or lower
values of clamp load can be used depending on the application
requirements and the judgment of the designer.
Notes:
1. Tightening torque values are calculated from the formula T=KDP
T=tightening torque (lb.-in.); K=torque-friction coefficient; D=nominal
bolt diameter (in.); P=bolt clamping load developed by tightening (lb.).

Composite Disc Springs
COMPOSITE
Composite disc springs have a significant advantage over
carbon steel because they are typically 70% lighter, noncorrosive, chemical resistant, and non-magnetic. Their
composite material construction provides a high strengthto-weight ratio compared to traditional metallic
construction and can be designed to provide the same
functional performance as steel components.
Composite disc springs are available in 2 designs: The CPW
series is intended for use comparable to a metallic disc
spring and the CCBS (Carbon Composite Bellows™ Spring)
series is designed to be used as a replacement for a helical
compression spring. The CCBS product features more
deflection than a standard disc spring, it does not require
the use of an ID or OD guide, and can be adapted for
varying rate curve requirements.
Contact Century Spring’s team of disc spring engineers
who can assist in integrating composite disc springs at the
design stage of new products and programs.

Series CDM Disc Springs
CDM Series Precision Disc Spring Tolerances
The following tolerances are for the CDM series disc springs
(AISI 1075 or 6150 carbon steel) and their stainless steel
counterparts (17/7 stainless).

Refer to the “CDM-S” columns for dimensional and/or
tolerance differences required for ALL 17/7 PH stainless
steel parts. ALL stainless steel materials will utilize these
CDM-S specifications with the exception of materials not
available in the standard tolerance range. In those cases,
the closest material tolerance will be used.
>
When requesting parts made of stainless steel, add the
letter “S” to the end of the existing part number. For
example, carbon steel part number CDM-502520 becomes
CDM-502520S for stainless steel.
t Range
For availability of other material types and achievable
tolerances, please contact the disc spring team for
assistance.
Design Note: stainless steel material thickness is different
than steel and is subject to commercial availability. The
overall height will be used to compensate for the difference
in load due to the difference in thickness.

Series CDS Disc Springs Sized for Bolts
CDS disc spring
series (prestressed) are used
to maintain load
or tension in
bolted assemblies.
Pressure begins in
the outer radius
and flattens gradually toward the bolt as deflection
progresses. Disc springs exert a uniform pressure that
remains constant, despite tension losses caused by thermal
expansion and contraction, compression set, or wear of
parts. Because pressures are predictable, disc springs
provide a simple and effective means of determining bolt
tension that is far more accurate than “torque” readings.
CDS, BB, CDS-S, BB-S Series
and Standard Spring Tolerances
ALL stainless steel materials will utilize these CDS-S or BB-S
specifications with the exception of materials not available
in the standard tolerance range. In those cases, the closest
material tolerance will be used.
When requesting parts made of stainless steel, add the
letter “S” to the end of the existing part number. For
example, carbon steel part number BB-6312 becomes
BB-6312S for stainless steel.
For availability of other material types and achievable
tolerances, please contact the disc spring team for
assistance.
Design Note: stainless steel material thickness is different
than steel and is subject to commercial availability. The
overall height will be used to compensate for the difference
in load due to the difference in thickness.
The tolerances on this page are for the CDS and BB (AISI
1075 or AISI 6150 carbon steel) and CDS-S and BB-S (17/7
PH stainless steel) series parts.
CDS
Refer to the “CDS-S” and/or “BB-S” columns for
dimensional and/or tolerance differences required for ALL
17/7 PH stainless steel parts.

Contact Disc Springs - Serrated
Very often disc springs are
considered for use as safety
washers for bolt connections to
maintain a pre-load and to
prevent loosening. For this
application, the sizes of normal disc springs do not match
the screw and bolt sizes. Century Spring now offers special
elements for this application.
Serrated disc springs are a form of disc
spring serrated on both sides of a
trapezoid cross section. Because their
diameters are matched to screw
dimensions, the serrated disc springs can
be used with practically any screw or bolt. The outer
diameter of the serrated disc spring will match up to the
head diameter of pan head and hexagon socket head cap
screws, including recessed heads.

Serrated disc springs offer the following advantages to a
designer:
• Locking effect at the outside diameter ensures the
greatest resistance to loosening
• Positive locking serrations increase resistance to
vibration
• Concentric application of force eliminates bending
bolts
• Sliding surfaces allow tightening with no surface
damage
• With proper transitional radius between bolt shaft
and head, there is no splitting when tightening
• Suitable for captive fitting on a wide range of bolts
• Minimizes stock with universal applications

Contact Disc Springs
Contact Belleville Disc Springs combine two important
features for improved bolt connections:
1. Their conical shape provides reactive force and a high
elasticity of spring return to compensate for developed
looseness, loss of bolt tension due to applied surface
deterioration, and movement due to the thermal expansion
and contraction.
2. The hardened, serrated profile grips the lower surface of
the bolt or nut to prevent the loss of tension that normally
occurs during extreme vibration or severe shock.
Contact Disc Springs come in sizes that correspond to a
wide range of screw head sizes, including hex head socket
screws. They can also be used in assemblies. The “Narrow”
Contact Disc Springs are designed for use in confined
space under a socket head screw. “Wide” Contact Disc
Springs are ideal for oversized holes in sheet metal
applications, making use of a wide bearing surface. All
Contact Disc Springs are made of selected high-quality
carbon spring steel.

Curved Disc Springs
CURVED
The cylindrically Curved Disc Spring, or curved disc washer,
is well suited for applications requiring flexibility, light loads
(from ounces up to about 100 pounds), and repeated
cycles through a range of motion. The curved disc spring
exhibits the most uniform spring constant over the widest
range of deflection compared to the wave and Belleville
type disc springs.
Curved disc springs are available in spring steel; call for
availability of stainless.

Wave Disc Springs
WAVE
A Wave Disc Spring or
wave disc washer is an
efficient method of
obtaining the required
loading when the load is
static, the working range is
small, and the allowable
amount of axial space is limited. Loads obtainable from
wave disc springs are usually in the range of a few pounds
to hundreds of pounds. These springs are often used as
cushion springs or cushion spacers between parts on
shafts, or to take up the expected amount of variation in

2) After first loading
A “K” factor of .2 was used for the dry torque calculation.
Use .15 if lubricated. The basic metric formula used for foot
pounds is T = K (D/12) P (T = torque, K = K factor for the
coefficient of friction and D = normal bolt diameter).

FL & MFL Series Flange Disc Springs
FL (inch) & MFL (metric) Series Flange Disc Springs are
elastic mechanical elements designed primarily for pipe
flange applications. When used in bolt joints that are subject
to thermal or mechanical shock, they deflect and move with
the bolted joint. Hence, they compensate for developed
looseness. The reactive power of the flange disc spring
serves to keep the bolt joint tight under all conditions.
Principal applications include piping construction,
compression joints, steam piping joints, valve and pump
connections, and others in the petrochemical field.
conditions, always use flange spring discs under the nut or
bolt head.
Pre-stressing or torquing the bolt at factory installation is
not sufficient to protect the flange joint under unexpected
temperature variations and mechanical shock loads in the
field. Flange spring discs absorb peak stresses, therefore
preventing damage to the bolt, gasket, and joint.
Material

Hardness:
17-7 precipitation hardened
Rc 40-45 for ID < 1.250 inches
Rc 38-42 for ID ≥ 1.250 inches
Temperature Range: –220°C to +300°C for higher
temperatures – to +600°C, Inconel™

non-standard)
Abnormally high loads, produced by thermal expansion
and contraction of a bolted joint, are a principle cause of
flange leakage. Generally, flanges are under static load
conditions. However, in large piping systems there may
also be mechanical shock from compressor related piping.
Thermal and mechanical shock differential can cause
variation and yielding in bolt loads. To protect against these

NDS (National Disc Spring) Flange Disc Springs maintain bolt
tension and gasket pressure around the flange, especially
under conditions of thermal variations or mechanical shock,
which may disturb the bolted joint. They counteract
loosening and assure the integrity of the bolted flange under
the most severe conditions. The proper use of NDS series
flange disc springs will ensure that the gasketed joints will
completely maintain the seal - no leaking, reducing pollution,
ensuring safety, and reducing pipeline downtime.
Flange disc springs are precision-machined on all surfaces,
with well-rounded edges. They are used as a single disc
spring or stacked on each end of the bolt, depending on
estimated bolt elongation.
NDS
NDS Series Flange Disc Springs
Material
H11/H13 steel is used, which can be used at high
temperatures. Under most conditions, the NDS disc springs
can withstand temperatures in the range of 1100°F (590°C).
The NDS series flange disc spring is “live loaded”, which
means it automatically adjusts for thermal variation,
vibration, and mechanical shock stress.

BB Series Disc Springs
BB (Ball Bearing) Series Disc Springs are specially designed
as preloading springs for use with radial ball bearings.
These disc springs help to maintain positioning accuracy of
the bearing with no endplay. They also minimize vibration
and shaft deflection. Proper preloading will increase
bearing rigidity and eliminate excessive running noise.
Material
C1075 Steel
17/7 PH stainless steel
Rockwell hardness C40-51
TOLERANCE
LOAD:
± 20% @ .75h
Refer to pages 18-19 for the standard spring tolerances of
the BB/BB-S Series Disc Springs.
FOR BALL BEARINGS
When requesting parts made of stainless steel, add the
letter “S” to the end of the existing part number. For
example, carbon steel part number BB-6312 becomes
BB-6312S.

Finger Disc Springs
Finger Spring Disc or
Finger Spring Washers
counteract noise,
excess wear, endplay,
and vibration,
especially at high
speeds. The finger
springs promote
efficiency and smooth
operation, reducing skidding wear on rotating elements.
They are also extremely useful in cases of unavoidable
loose, internal clearances due to special application
conditions.
Material
Finger spring discs are made of high carbon steel
commercial 1074.

Slotted Disc Springs
The inclusion of slots on either the inner or outer diameter
creates a lever that works on the un-slotted portion of the
spring. This effect reduces the spring load and increases
the deflection, giving the spring a softer characteristic with
larger deflection, in proportion to the outside diameter
smaller spring loads.
With this type of spring, it is most important that the
permissible stresses in the annular portion are not
exceeded. If necessary, the outside diameter must be
increased to compensate.
Benefits of slotted disc springs include:
• Generates very small loads
• Accommodates large deflections
• Achieves quiet-run bearing assembly
• Accommodates the build up of tolerances within
assembly
• Eliminates thermal movements
SLOTTED
Material
Slotted disc springs are made of spring steel; call for
availability of stainless steel.

Applications for Disc Springs
APPLICATIONS
Disc springs are used in applications throughout a wide
range of industries and markets. A few examples showing
the use and importance of MWI’s disc springs include:
Valve Actuator Assembly
Normal spring
return actuators:
The electrical or
pneumatic
actuator
compresses the
springs to actuate
the valve. When the controller releases power or pressure,
the force stored in the spring returns the actuator to its start
position, allowing for simpler and less expensive
control/actuator systems.
Fail-safe spring actuators: During powered operation the
springs travel with the actuator. The actuator opens and
closes the valve, and provides braking. Under loss of
power, the spring is released and drives the actuator to the
pre-designated fail-safe position.
Shock Absorbing Bolted Assembly
Disc springs are
largely selfdamping,
particularly when
they are stacked in
parallel. This
makes the springs
useful in dissipating energy in bolted assemblies that are
subjected to shock loading and vibration.
Punch Stripper Assembly
Stacks of disc springs can be used to
provide the retraction force
(“stripping”) for punches. The
compact size of the springs is ideal for
punch cassettes that can be used in
CNC punch machine tool changers.
40
Fail-Safe Brake
Assembly
In many machinery
applications it is
necessary that a brake
be applied in case power
to the equipment is lost.
In these situations disc
springs can be installed so that they are compressed
when the machine engages to release the brake and
then, if power is lost, the springs apply the brake and stop
the machinery.
Cable Support Assembly
Often when materials such as wires
or cables are clamped using a screw
or bolt, the wire or cable will
compress over time and the
assembly will become loose.
Disc springs can provide for this
compression and keep the
assembly tight.
Pipe Hold-Down Assembly
Long pipe runs require structural support, but are also
subject to movement due to temperature changes. A
structural support that includes disc springs can both
support and control the pipe, by allowing some movement
when required.

Shock Absorber Assembly for Drill Bit
Deep down-hole drilling for oil and gas exploration creates
extreme shock loads on the drill bits. Stacks of disc springs
can be used to cushion the drill bit, giving it a longer bit life.
Friction Assembly
Friction assemblies like clutches,
traction drives, and brakes use
disc springs to provide even
pressure as friction materials
wear away and actuation
deflections change.
Live Loaded Joints
Many joints, particularly pipe
flanges are subject to loosening
due to temperature change
cycles. This loosening often
results in leakage at the joints.
Disc springs are part of a “live
loading” assembly that help
maintain leak-tight joints, greatly
reducing maintenance costs.
APPLICATIONS
Applications for Disc Springs
Valve Packing
Assembly
Disc springs are used in
valves to maintain pressure
on the packing so that the
seal around the valve stem
does not leak. Over time
the packing material will
compress and the disc
springs will take up the slack.

High Pressure Valve
Disc springs are used to provide
control in pressure valves. The disc
springs keep the valve closed until the
control fluid pressure rises to the point
where it overcomes the designed load
of the springs, and at that point, the
valve opens releasing pressure.
