3 Design of Screw Shaft
3.1 Production Limit Length of Screw Shaft
3.2 Method for Mounting
Production limit length of precision ground Ballscrew:
The permissible axial load and permissible rotational speed vary with the screw-shaft mounting method
used, so the mounting method should be determined in accordance with the operating conditions.
Diagrams 3.1 through 3.3 illustrate a typical method for mounting a screw shaft.
When screw shaft O.D. is 6 mm, Limit length of Ballscrew is 150 mm.
Note: Please contact with our sales people in case a very high dm.n value is required.
Permissible axial Laod = fixed - fixed
Permissible rotaional speed = fixed - fixed

(2) dm.n Value of Ballscrew:
3.3 Permissible Axial Load
(1) Buckling load：
The Ballscrew to be used should not buckle under
the maximum compressive load applied in its axial
direction. The buckling load can be calculated by
using equation (3.1):
(kgf )
( 3. 1)
Here:
α
Safety factor ( α=0.5)
E
Young's modulus (E=2.1×104kgf / mm2)
I
Minimum geometrical moment of inertia
of the screw shaft cross section (I=πdr4/ 64
mm4)
dr
Screw shaft thread minor diameter (mm)
L
Distance between mounting positions (mm)
(2) Permissible tensile-compressive load of the
screw shaft：
Where the axial load is exerted on the Ballscrew,
the screw shaft to be used should be determined
in consideration of the permissible tensile compressive load that can exert yielding stress on
the screw shaft.
The permissible tensile-compressive load can be
calculated using equation (3.2).
Here:
dm is the BCD (ball circle diameter) of screw shaft,
and n is the maximum rotation speed. The dm.n
value relates and affects the noise, temperature
raise, working life, balls circulation of the ballscrew.
In general cases, the dm.n value is limited as
follows: (See Note one)
Precision ground：dm.n≦70000
Rolled：
dm.n≦50000
Note one:
These dm.n values are for reference only. In fact,
the dm.n value shall be decided by the ways of end
supporting and the distance between them.
Note two:
Please contact with our sales people in case a very high
dm.n value is required.
With better manufacturing technology currently,
the dm.n value is no longer limited as above. It is
even higher than 100,000. (See Note two)

3.5 Notes on Screw shaft design
(N=1)
(N=2)
(N=4)
(N=1/4)
(1) Through end thread:
For the Ballscrews with internal ball circulation
Ballnut, it is required to have at least one end with
complete thread to the end of Ballscrew for Ballnut
assembly to screw shaft. If it is impossible for
through end thread, it is required to have at least
one end with complete thread and the journal
area is with diameter to be 0.2mm smaller than the
diameter of thread root area.
3.4 Permissible Rotational Speed
(1) Critical rotation speed：
When the rotation speed of driving motor
coincides with the natural frequency of feed system
(mainly the ballscrew), the resonance of vibration
shall be triggered. This rotation speed is then called
critical rotation speed. It shall make bad quality
machining, since there is wave shape surface
on the workpiece. It may also cause damage of
machine. Hence it is very important to prevent the
resonance of vibration from happening. We choose
80% of critical rotation speed as allowable speed. It
is shown as formula (3.3).
Here:
n
Permissible rational speed (rpm)
α
Safety factor (α=0.8)
E
Young's modulus (E=2.1×104kgf / mm2)
I
Minimum geometrical moment of inertia of the
screw-shaft cross section (I=πdr4/ 64 mm4)
dr
Screw-shaft thread minor diameter (mm)
A
Screw shaft cross-sectional area (A=πdr / 4 mm )
L
g
Gravitation acceleration (g =9.8×103 mm/s2)
γ
Specific gravity (γ=7.8×10-6 kgf/mm3)
2
2
f、λ Coefficient depending on the mounting method
It may be required to have additional supports in
between the ends bearing supports to make the
natural frequency of Ballscrew to be higher and
hence to raise the allowable rotation speed.

f =3.4
(λ=1.875)
(2) Machine design for the area of Ballnut and
ends area of Ballscrew:
It is very important to check if there is enough
space for assembly of Ballscrew onto the machine
during machine design. In some cases, there is
not enough space for assembly and the Ballnut
has to be disassembled from the screw shaft for
easier work. It may cause problems, such as the
balls falling out from Ballnut, worse accuracy of
squareness and roundout of Ballnut, change of
preload and damage to external ball circulating
tubes. In some more serious cases, the ballscrew
may be damaged and not to be used. Please
contact with our people if said above disassembling
is required.
(3) Not effective hardened area:
The threads on screw shaft are hardened by
induction hardening. It shall cause about 15mm at
both ends of thread area are not hard enough. It is
required to pay attention during machine design
for the effective thread length of travel.
(4) Extra support unit for long ballscrew:
For a long ballscrew, the bending due to self weight
might happen. It may cause radial direction load
to ballscrew. The radial direction vibration during
rotation might also be more serious. To prevent
these problems from happening, it may be required
to have extra supports for ballscrew in between the
existing supports at both ends. There are two types
of supports; one is movable to move along the
Ballnut. The other one is fixed type; it is located in
a fixed position. The Table must be designed not to
hit with this support during moving.

Design of Ballnut
When Ballscrew takes only axial load, the best performance of it shall be found; the balls on the groove in between
the Ballnut and screw shaft shall evenly take the load and rotate smoothly. In case there is torsional load or radial
load on Ballnut, this kind load shall be taken unevenly by some balls only. It shall badly affect Ballscrew performance
and even shorten ballscrew life. It is recommended to pay more attention to the mechanism design and Ballscrew
assembly.

components of it.

5.1.3 Ballscrew's preload and effect
In order to get high positioning accuracy, there are two ways to reach it. One is commonly known as to clear axial
play to zero. The other one is to increase Ballscrew rigidity to reduce elastic deformation while taking axial load. Both
two ways are done by preloading.
(1) Methods of preloading
a.Double-nut method:
A spacer inserted between two nuts exerts a
preload. There are two ways for it.
One is illustrated in Fig.5.1. That is to use a spacer
with thickness complies with required magnitude
of preload. The spacer makes the gap between Nut
A and B to be bigger, hence to produce a tension
force on Nut A and B. It is called "extensive preload".
b.Single-nut method:
As that illustrated on Fig. 5.3, using oversize balls
onto the space between Ballnut and screw to get
required preload. The balls shall make four-point
contact with grooves of Ballnut and screw.
Lead
The load in nut A and nut B are:
FA=Fao+Fa-Fa'=Fa+Fp
FB=Fao-Fa'=Fp
Fig.5.3 Four-point contact preload
Fig.5.1 Extensive preload
Illustrated in Fig.5.2, is using a thinner spacer.
The thickness complies with required magnitude
of preload. The spacer is smaller than the gap
between Nut A and B, compressing Nut A and B
on opposite direction to preload Ballscrews. It's
called "compressive preload".
There is another way for single nut Ballscrew
preloading. That is to shift a very little distance,
which complies with required magnitude of
preload, on one lead of Ballnut as that illustrated
on Fig. 5.4. to preload Ballscrew.

Spacer
Direction of tension
Lead + offset
Nut
Nut B

Screw
It means Fa is offset with an amount Fa' because
of the deformation of Nut B decreases. As a result,
the elastic deformation of Nut A is reduced. This
effect shall be continued until the deformation
of Nut B becomes zero, that is, until the elastic
deformation δa1 caused by the external axial force
equals δao, and the preload force applied to Nut
B is completely released. The formula related the
external axial force and elastic deformation is
shown as below:
Displacement of Nut A
Fa
Fao
Fp
Displacement

Fig.5.6 Positioning preload diagram

Lead
Therefore, the preload amount of a ballscrew
is recommended to set as 1/3 of its axial load.
Too much preload for a Ballscrew shall cause
temperature raise and badly affect its life. However,
taking the life and efficiency into consideration,
the maximum preload amount of a Ballscrew is
commonly set to be 10% of its rated basic dynamic
load.
Shown on Fig 5.7, with the axial load to be three
times as the preload, the elastic displacement for
the non-preloaded ball Nut is two times as that of
the preloaded Nut.

5.2 Positioning Accuracy
6.1 Life of the Ballscrew
5.2.1 Causes of error in positioning accuracy
5.2.3 Considering thermal displacement
Even though the Ballscrew has been used with correct manner, it shall naturally be worn out and can no longer be
used for a specified period. Its life is defined by the period from starting use to ending use caused by nature fail.
Lead error and rigidity of feed system are common
causes of feed accuracy error. Other causes like thermal
deformation and feed system assembly are also playing
important roles in feed accuracy.
If the screw-shaft temperature increases during
operation, the heat elongates the screw shaft,
thereby reducing the positioning accuracy. Expansion
and shrinkage of a screw shaft due to heat can be
a.Fatigue life - Time period for surface flaking off happened either on balls or on thread grooves.
b.Accuracy life - Time period for serious loosing of accuracy caused by wearing happened on thread groove
surface, hence to make Ballscrew can no longer be used.

6.2 Fatigue Life
ΔLθ
5.2.2 Selecting the lead accuracy
Refer to page 10, the Specified travel line should
coincide with the nominal travel line. However, in
order to compensate either the elongation caused
by the thermal expansion during machine operating
or the shortening of length due to external load, the
specified travel may be set to be positive or negative
to the Nominal travel. Machine designer can show
the value of Specified travel on the drawing for our
manufacturing, or, we can help to decide it based on
our more than ten years experience.
There is another way to compensate thermal effect by
"pretension" to Ballscrew. Generally, the pretension
force shall elongate the Ballscrew to be equivalent to
the thermal expansion at about 2-3℃.

temperature of 1℃ expands the shaft by 12μm per
meter. The higher the Ballscrew speed, the greater
the heat generation. Thus, temperature increases
reduce positioning accuracy. Where high accuracy is
required, anti-temperature-elevation measures must
be provided as follows:
(1) To control temperature:
• Selecting appropriate preload.
• Selecting correct and appropriate lubricant.
• Selecting larger lead for the Ballscrew and
decrease the rotation speed.
(2) Compulsory cooling:
• Ballscrew with hollow cooling.
• Lubrication liquid or cooling air can be used to
cool down external surface of Ballscrew.
(3) To keep off effect upon temperature raise:
• Set a negative cumulative lead target value for
the Ballscrew.
• Warm up the machine to stable machine's
operating temperature.
• Pretension by using on Ballscrew while installing
onto the machine.
• Use the Closed-loop positioning control.
The basic dynamic rate load (Ca) of the Ballscrew is used to calculate its fatigue life when it is operated under a load.
6.2.1 Basic dynamic rate load Ca
The basic dynamic rate load (Ca) is the revolution of 106 that 90% of identical Ballscrew units in a group, when
operated independently of one another under the same conditions, can achieve without developing flaking.
6.2.2 Fatigue life

There are three ways to show fatigue life:
a.Total number of revolutions
b.Total operating time.
c.Total travel.

When l=8(mm) ................Ca≧3756 (kgf )
If life > 25000 (hours) is needed,
Ca must be > 3756 (kgf )
When l=10(mm) ...............Ca≧3487 (kgf )
If life > 25000 (hours) is needed,
Ca must be > 3487 (kgf )
Ballscrew shaft diameter can be decided by critical rotation
speed of high speed feed.
Assume both of the supporting ends are fixed.
So the permissible rotational speed :
L = Max. stroke + Nut length/2 + unthread area length
= 1000 + 100 + 200 = 1300 (mm)
Screw shaft supported method is fixed-fixed
f = 21.9
when l =8 (mm) ......................dr ≧13.5 (mm)
If the highest rotational speed reaches 1750 rpm,
screw shaft diameter at thread root area must be bigger
than 14 mm.
◎So screw shaft diameter shall be ranged in between 20 and 50 mm.
When l =10 (mm) .................... dr ≧10.8 (mm)
If the highest rotational speed reaches 1400 rpm,
screw shaft diameter at thread root area must be bigger
than 11 mm.
(5) Considering rigidity
By initial conditions:
Lost motion：0.02 mm (no load)
Assume total displacement of components (including screw
shaft, ballnut and support bearing) of feed system is 0.016 mm.
Thus the unilateral elastic displacement of feed system is

11 PMI Ballscrew With Hollow Cooling System
PMI 's design of hollow cooling system is especially good for high speed Ballscrews. It shall well dissipate heat
generated by friction between balls and grooves during Ballscrew running, and then to minimize thermal
deformation as to ensure positioning accuracy.
11.2.3 End sealing
11.1 Introduction to Hollow Cooling System
11.2.4 Coolant pipe support installation
The hollow cooling system is designed by PMI (Fig.11.1) It uses a coolant pipe through the hollow hole of Ballscrew.
The hollow hole is through all of the Ballscrew, and one end is clogged with the oil seal by PMI patent. The coolant
is pumped into coolant pipe and flow to the end of coolant pipe. Coolant then flow reversely along the hollow hole
back into the coolant collector. It can cool down the Ballscrew. The coolant is then sucked back to the cooling unit to
drop coolant temperature and pumped again to the coolant pipe to complete circulation.
Supported the coolant pipe. Let it don't touch
Ballscrew.

Additional Remarks
1.Using the high dustproof scraper may induce an increase in preload. If your machine has a strict requirement on
the range of preload, please contact PMI engineers.
2.High dustproof seal washers should not be used in an environment where the temperature exceeds 60℃.
3.Due to potential sealing problems with returning tubes, please contact PMI engineers if you need to use external
ball circulation nuts (such as FSWC and FSVC).

Low Noise
The average and accurate ball circle diameter (BCD)
through whole threads make the ballscrews to obtain
the stable and consistent drag torque as well as to
reduce the noise.
The audio frequency is low and deep due to the
designed of plastic circulation system.

Space Saving
158
The ballnut diameter reduces 20%~25% substantially
and the length of nut is shorter.
The total space shall be reduced to approximately 50%
consequently.

Circulation
288
The specially designed pathway of the
Recirculation System makes a contact
with lead angle and also with BCD in
the same tangency, improving its
smoothness effectively.

High DN Value
The DN value can be 130,000 in normal case. For
some special cases, for example in a fixed ends
case, the DN value can be as high as 140,000.
Please contact our engineers for this special
application.
High Speed
PMI 's High-speed Ballscrews provide 100 m/min
and even higher traverse speed for machine
tools for high performance cutting.
High Rigidity
Both the screw and ballnut are surface hardened
to a specific hardness and case depth to
maintain high rigidity and durability.
Multiple thread starts are available to make
more steel balls loaded in the ballnut for higher
rigidity and durability.
Low Noise
Special design of ball circulation tubes offer
smooth ball circulation inside the ballnut. It
also makes safe ball fast running into the tubes
without damaging the tubes.
Accurate ball circle diameter (BCD) through
whole threads for consistent drag torque and
low noise.

13.5 Ballscrews For Heavy Load
Q(oil hole)
W
Focused on improvements of contact points of balls
and thread grooves, ball diameter and circulation
system for new type, FSVH. The rated dynamic load has
been increased to as two times as that of conventional
type, FSVC.
W
UNIT:mm
BALL
O.D. LEAD
Long Life
Low Noise
Structure of the newly developed circulation system is
designed to distribute the load uniformly to the load
balls and it also increases the life of ballscrews.
On conventional circulation system, FSVC, the
returning tube is inserted into the holes on ballnut
perpendicularly which forms an advancing angle.
While ball moves into returning tube, it will hit tube
end area and then move into returning tube.
New circulation system, FSVH, ball will move into
returning tube smoothly by tangent line as the same
direction as lead angle. It can increase the life of
circulation system structure.
To use tangential circulation system structure, it can
eliminate the noise while balls run into the returning
tube.

We employ the most advanced digital
electric screw thread rolling machine.
During the manufacturing process, the oil
cylinders on the two axes of the thread
rolling dies employ a servo hydraulic
system for the correction of oil pressure
and positioning precision.
We employ Germany-impor ted Bad
Düben roller in order to maintain the
stability of the thread rolling machine and
the quality of the rolled product.
PMI rolled ballscrews offer a variety of specifications, lead accuracies, and maximum rolling length, as shown in

Features
Short Delivery
In order to achieve the purpose of standardized
stock for short delivery time, the precise outer
diameter of screw shaft is used for support
bearing seat.
Flexibility of stroke length
Due to the precise outer diameter of screw
shaft is used for support bearing seat, the
specific length of shaft can be freely cut from
standardized screw shaft. Therefore, the flexible
stroke length is allowable for simple support
end.
Space saving
Comparing with conventional ballscrew, the
outer diameter of nut is reduced as 20~25% as
much, and the nut length is also shorter than
usual. Therefore, the mounting space can be
saved from engineering design.
High speed and lower noise
Taking advantage of PMI unique technology of
high-speed, noise reduction, the rotation speed
can be as higher as 5000 rpm. Moreover, due
to the design of special circulation system, the
vibration and noise(6 db less) are much lower
than conventional type of ballscrew.
High accuracy with reasonable price
The accuracy can be as higher as JIS C5 grade
and with axial clearance within 5 μm.
Application range
Semiconductor equipments, Measuring devices, Inspection equipments, Medical equipments,
Automation, Light load machining, Glue depositing, and other precision motion and positioning
applications.

4.3 Static Safety Factor ( fs )
Due to the impact and vibration while the guideway at rest or moving, or the inertia from start and stop, the linear
guideway may encounter with an unexpected external force. Therefore, the safety factor should be taken into
consideration for effects of such operating loads. The static safety factor ( fs) is a ratio of the basic static load rating (C0)
to the calculated working load. The static safety factor for different kinds of application is shown as Table.

The trains of balls are designed to a contact angle of 45° which enables it to bear an equal load in radial, reversed
radial and lateral directions. Therefore, it can be applied in any installation direction. Furthermore, MSA series can
achieve a well balanced preload for increasing rigidity in four directions while keeping a low frictional resistance. This
is especially suit to high precision and high rigidity required motion.

B. Characteristics
The trains of balls are designed to a contact angle of 45° which enables it to bear an equal load in radial, reversed
radial and lateral directions. Therefore, it can be applied in any installation direction. Furthermore, MSB series can
achieve a well balanced preload for increasing rigidity in four directions while keeping a low frictional resistance. This
is especially suit to high precision and high rigidity required motion.
The patent design of lubrication route makes the lubricant evenly distribute in each circulation loop. Therefore, the
optimum lubrication can be achieved in any installation direction, and this promotes the performance in running
accuracy, service life, and reliability.
Compact, Four-way Equal Load
Compact design of the carriage with the four trains of
The self adjustment is performed spontaneously as
balls are allocated to a circular contact angle at 45°,
the design of face-to-face (DF) circular arc groove.
thus each train of balls can take up an equal rated load
Therefore, the installation error could be compensated
in all four directions. Moreover, a sufficient preload
even under a preload, and which results in precise and
can be achieved to increase rigidity, and this makes it

The Optimization Design of Four Directional Load
MSR linear guideway through rollers have a line
Through the structure stress analysis of finite element
contact with carriage and rail. Relative to the general
method, SMR series have four trains of rollers are
type linear guideway through balls have a point
designed to a contact angle of 45° and the section design
contact; the MSR type linear guideway can offer lower
for high rigidity. Except for bearing heavier loads in radial,
elastic deformation while bearing the same load. Base
reversed radial and lateral directions, a sufficient preload
on the rollers have the same outer diameter with balls,
can be achieved to increase rigidity, and this makes it
the roller can bear the heavier load. The excellent

H. Maximum Travel Speed and the Maximum Length
I. Life Calculation
KM series is limited by the dangerous speed of the ballscrew and the DN value regardless, the maximum travel speed and the
maximum length are shown below.
Unit：mm
KM series consists of a linear guideway, a ballscrew and a support bearing. The calculation of nominal life of each component is
shown below. The nominal life is defined as the total running distance that 90% of identical linear guideways or ballscrew in a
group, when they are applied under the same conditions, can work without developing flaking.
