WARNING
When using ARAMID FIBER REINFORCED BELTS be sure NOT to tension at higher force than recommended for
standard conventional construction belts.
Higher tension may result in body injury and premature failure of bearings and other drive components. Specially
designed sheaves may be required to match drive specification when using this type of belts.
NOTE: All dimensions are subject to change without prior notice

“QD” INTERCHANGEABLE BUSHING
Check these high quality features...
TAPERED, PRECISION FIT.
Precision machining of the tapered bore in the hub of the QD rim and the tapered
mating surface of the bushing insures a snug, precision fit between rim and bushing.
Tightening the cap screws draws the sheave up tight on the bushing - Maska QD
Bushings and Sheaves are true running.
FULL - NOT PARTIAL SPLIT.
This feature, together with the tapered, precision fit of rim and bushing, enables the
QD Bushing to compress evenly around the entire circumference of the shaft,
gripping it with tremendous pressure, the equivalent of a press fit on the shaft. And the
full split makes it just as easy to install QD Sheaves on all standard size shafts as it is
to install them on shafts which may be slightly oversized or slightly undersized.
EASY TO INSTALL, EASY TO REMOVE.
To install Maska QD Sheaves, the cap screws are used as pull-wrench only - no
additional leverage is necessary. To remove QD Sheaves, the cap screws are taken
out and used as jack screws. A few quick turns on each screw, and the tight grip of the
bushing on the shaft is easily broken.
Ductileor Gray
SET SCREW OVER THE KEY.
Once the correct position of the QD Sheave on the shaft is determined, tightening the set screw in the bushing head down on the key will hold
the bushing in this position while the pull-up bolts are tightened. This set screw holds the key in place on the shaft during drive operation - an
especially desirable feature on drives that have vertical shafts. Available on all QD bushings except W AND S.
FULLY INTERCHANGEABLE WITH OTHER “QD” BUSHINGS.
As in the case of Maska QD Sheaves, the QD Bushings also conform to standardized QD dimensions and sheave types. Because of this
feature, any QD Stock Bushing may be interchanged with the same size bushing that other QD manufacturers produce.

“QD” BUSHINGS BORE
AND KEYSEAT DIMENSIONS
Tapered Bushings are available from stock in all bores and keyseats listed below. In some cases, as the bore increases in diameter, a shallow keyseat
is provided - due to insufficient metal thickness. When this happens, Maska furnishes the correct rectangular key (inches only) at no charge. This does
not affect the bushing’s ability to transmit the load. The rectangular key, or flat key as some call it, fits into the standard keyway in the shaft.

TAPER-LOCK BUSHINGS
To Install:
1. Clean all parts of the bushing and bore of hub thus removing any oil, lacquer
or dirt. Install bushing in hub and match half holes to make complete holes
(each complete hole will be threaded on one side only).
2. Oil thread and either the end of set screws or under the head of the cap
screws. Install screws loosely in holes that are threaded on the hub side.
3. Make sure that the bushing is free in the hub. Slip assembly onto shaft and
align in the desired position.
4. Tighten screws evenly and alternately until the part has tightened. (See table
on following page for wrench torque)
5. Hammer with a block or sleeve the large end of the bushing. Re-tighten
screws using the correct torque. Repeat this procedure until the screws no
longer turn. Fill remaining holes with grease to prevent dirt buildup.
To Remove:
WARNING: DRY MOUNTING
DO NOT USE LUBRICANTS OR
ANTI-SEIZE COMPOUND.
1. Remove all screws. Oil thread and either the end of set screws or under the
head of cap screws.
2. Insert screws in hole(s) that are threaded on the bushing side (see diagram on
following page). Note that there will be one extra screw left over.
3. Tighten screws alternately until the bushing is loose in the hub. It may be
necessary to tap on the hub to loosen the bushing.

“VECOBLOC® SCL” KEYLESS BUSHING
ADVANTAGES
Manufactured from steel and machined with
precision, the Vecobloc¤ bushing allows for
installation of the component on the shaft without a
key.
This means cost savings as the keyway does not
have to be machined on the shaft.
Makes synchronisation, indexing and axial
positioning easier.
This product is manufactured in cooperation with Colmant Cuvelier®

To Install:

-
3
1. Front cone (6 holes)
2. Back cone (4 holes)
3. Screws & lockwashers
The torque is transmitted by friction. All contact surfaces (cone & bore) must be
clean. Do not use lubricants or anti-seize compound on tapered bore or bushing
suitcase.
Install the back cone (2) on shaft.
Install the sheave on the back cone.
Install the front cone (1). The slots must be aligned. Be careful of proper drive
alignment before tightening.
Tighten the screws (3) alternately and evenly, in a cross pattern, until you obtain the
required tightening torque. Check the alignment.
To Remove:
-
Loosen the 4 screws and place two of them in the threaded holes of the front
cone (1).
Tighten these 2 screws alternately to separate the cones. If one cone remains
stuck in the sheave, you may gently hammer either the cone or the sheave. Use
of a puller may be required.

T : Type. Suffix indicates construction: A = arms; B = block; W = web.
NOTE: Metric, or additional special bores, are made to order only items. Contact Maska for price and delivery.
OR (alternative) for immediate use, Maska suggests using an MAL, MBL, 2MAL or 2MBL (see pages 20-21) for a stocked product.
CAUTION: DO NOT use these gray cast iron sheaves with rim speeds in excess of 6500 feet per minute. Note that the max. RPM
indicated on the arm of the sheave is based on the 6500 ft/min. limit, and doesn’t take into consideration the need for dynamic
balancing (two planes). Please refer to page 31 to verify the validity of dynamic balancing in your application. All operational PT
products when used in a drive are potentially dangerous and must be guarded by the user as required by applicable laws,
regulations, standards and good safety practice. (Refer to ANSI Standard B15.1)

CAUTION: DO NOT use these gray cast iron sheaves with rim speeds in excess of 6500 feet per minute. Note that the max. RPM indicated on the arm of
the sheave is based on the 6500 ft/min. limit, and doesn’t take into consideration the need for dynamic balancing (two planes). Please refer to page
31 to verify the validity of dynamic balancing in your application. All operational PT products when used in a drive are potentially dangerous and
must be guarded by the user as required by applicable laws, regulations, standards and good safety practice. (Refer to ANSI Standard B15.1)

V-Belt Drive Accessories
Indispensable tools for maintenance mechanics to ensure
efficient, cost-saving operations.
V-Belt Tension Tester
Part No. 006347
Net Price:
$10.90 USD
$14.50 CAN
checking the required force and the belt deflection
distance. For use with all small V-belt and synchronous
drives.
Comes in a protective plastic tube, instructions
included.
Force Range: 0-35 lbs.
Tension Range: 0-560 lbs.
0-15.9 kg
0-255 kg
Improper belt tension, either too tight or too loose, can
result in belt drive problems. For critical drives, a manual
verification is insufficient.
This indispensable maintenance tool is a handy way of
checking belt tension on single strand belts up to 1 wide
within the above ranges. Scales are provided for
Maintenance Pointers:
¥ Belts that are too loose will slip, causing excessive
belt and sheave wear. Sagging belts can snap
during start-up or during peak loads.
¥ Proper tension and installation can lengthen belt life
and lessen expensive downtime.
¥ Belts that are too tight can damage bearings.
¥ Both situations reduce power transmission
performance levels.
Sheave & Belt Gage
Part No. 006346
Net Price:
$2.50 USD
$4.00 CAN
Molded plastic & color-matched with our V-belt sheaves.
9 keys for grooves & 2 for belts.
To determine whether the sheave groove is worn, select
the proper sheave gage and insert the correct angle,
based on the sheave s diameter, into the groove. For all
Classical, Narrow
and A/B combination sheaves.
Note:
You can
also use these
gages to determine the corresponding
belt
MASKA
that fits with each
sheave. Find the
gage that fits,
depending on size
(groove must not
be worn), and the
c h a r a c t e r s
30
indicated on the gage will identify the belt type.
The belt gages help you determine the proper belt
section; just insert the old belt in the V to determine belt
cross section.
Maintenance Pointers:
¥ Inspect sheaves often for optimal operating
efficiency. Worn grooves cause one or more belts to
ride lower than the others, known as differential
driving , resulting in premature wearing of belts and
reduced performance levels.
¥ Rounded sheave
sidewalls
ruin
belts quickly by
wearing
their
bottom corners
(see illustration).
The
belt s
wedging action is
also reduced.
¥ If more than 1/32
of
wear
is
evident, reduced
V-belt life will
result.
Not more than 1/32 wear
COMPLEMENTARY INFORMATION
Ratio
A ratio is a proportional factor between two similar objects of different sizes. In a belt drive system, a ratio is used
to determine the speed relation between two pulleys. The speed ratio would be stable if slippage did not occur;
however as belt slip is inevitable, the ratio varies and is therefore only theoretical. If the ratio is >1, we refer to a
speed up system; if the ratio is <1, it is a speed reduction system. In both cases, the ratio is obtained using the
dimensions of the input drive (driver) pulley and the output (driven) pulley.
In the following ratio, RS is the speed ratio, D1 the diameter of the driver pulley, D2 the diameter of the driven pulley:
Speed & Velocity
With reference to a belt drive system, the formula to find rim speed, or belt speed, is:
OR
Power
In mechanical engineering, power is a measure of performance or capacity and is defined as the amount of work
performed in a given time. The most work accomplished in the least amount of time, equals greater power. This
formula also shows the relation between torque and HP.
Power in hp (HP) can be calculated using the following formulas:
OR
HP can be converted to kilowatts as follows:
HP = Kilowatts X 1.341

BALANCING STANDARDS
NOMOGRAPH
This nomograph shows the maximum speed limit (in RPM) for a gray cast iron standard statically balanced pulley of
a given diameter and face width. To exceed this speed limit, the pulley should also be dynamically balanced.
Example: If you have a 6-8V14.0 pulley (see 8V section) with a diameter of 14 and a face width of 7 1/8 , and it must
turn at 1,800 RPM, what type of balancing is required?
Answer: As shown, the limit for this pulley would be 1,500 RPM, therefore it must be dynamically balanced.

MASKA’S UNIQUE HUB DESIGN
Our Timing Pulley is designed with a double-tapered hub that
can be installed with our new Vecobloc¤ SCL keyless bushing
OR with a standard taper-lock bushing . . FROM EITHER SIDE.
The Vecobloc¤ SCL bushing eliminates the use of a key which
means perfect synchronisation AND not having to machine a
keyway on the shaft.
Product Features:
-
Synchronized no-slip transmission
No lubrication required
Compact design
High efficiency
Low maintenance, economical operations

NBR (Rubber) Nitrile Butadiene Rubber -40¡ to +212¡ F
is an elastomeric element that is oil
resistant with the resilience and elasticity -40¡ to +100¡ C
of natural rubber.
Most economical and widely-used
element.
Urethane -- Urethane has 1.5 more
torque capability than NBR, provides
less dampening effect and has good
resistance to oil and chemicals.

Jaw Couplings Advantages
Jaw design is considered fail-safe - if the insert element
wears/breaks away, the coupling continues to operate until
insert can be conveniently replaced.
Simple design means easy installation, removal and visual
inspection. Also greater radial softness, lighter weight and
lower cost vs. torque capacity, quiet operations and easy
replacement in the field.
Insert Choice
The choice of the insert element can make a significant
difference in the couplings s performance with regards to
BE SURE TO SPECIFY
vibration, temperature, chemicals, misalignment, high rpm,
space limitations and installation/removal.
Maintenance Tips
Through manual inspection, avoid allowing the jaw tips to come
into contact; a noisy, grinding operation will result. Do not
hesitate to replace the insert if signs of wear are evident.
Do not over-estimate service factors when choosing the
coupling / insert. This increases costs unnecessarily and can
cause damage elsewhere in the drive. Due to the variety of
inserts available, careful selection will result in efficient, longlasting operations

CURVILINEAR SYNCHRONOUS BELTS (H.T.B.)
Oil, heat and abrasion-resistant
The standard trapezoidal tooth timing belt design performs poorly in high
torque applications and high power drives at lower speeds. To overcome
this disadvantage the curvilinear belt was developed using a more
efficient tooth profile.
8mm Curvilinear Synchronous Belts
Width(mm)
Belt
Profile,
Length
& Pitch
Code
Our stock 8mm and 14mm curvilinear synchronous belts are listed below.
Non-standard lengths in these pitches are also available, as are belts with
3mm and 5mm pitch.
Curvilinear synchronous belts are specified by tooth profile and belt pitch
length, tooth pitch and belt width in millimeters.
For example:
720
–
(Belt Pitch Length)
(mm)
8M
(Tooth Pitch)
(mm)
–
30
(Belt Width)
(mm)
A. A high-modulus fiberglass cord is wound across the entire width of the
belt pitch line insuring minimal stretch and resistance to repeated
flexing.
B. The body is a synthetic neoprene compounded to resist flex fatigue, heat, ozone, mineral
lubricating oils and aging.
C. A tough nylon fabric is bonded to the tooth
surface for wear resistance.
Among the advantages are:
¥ Higher torque transmission at low speeds
¥ High power transmission over a wide speed range
¥ Improved meshing to reduce tooth jump
¥ Higher resistance to tooth shear
¥ Less tooth wear due to friction

TRAPEZOIDAL SYNCHRONOUS BELTS (Timing)
Stock trapezoidal synchronous belts are listed below.
They have fiberglass tension members and neoprene
body with nylon covered teeth, all bonded together for
maximum strength.
For non-stock widths, specified widths from our large
supply of belt sleeves are available on special order.
Mini-pitch MXL (.080-inch pitch) trapezoidal synchronous
belts are also available; they are specified by belt length
in inches times 10, belt pitch code and a three-digit belt
width code which is the decimal inch-width multiplied by
100.
A sample specification is shown below:

BELT TENSIONING INSTRUCTIONS
Synchronous Belts
V-Belts & Multi-Rib Series
Hign torque, Standard and Metric synchronous belts should be
installed to fit pulleys snugly, neither too tight nor too loose. The belt s
positive grip eliminates the need for high initial tension. When a belt is
installed with a snug but not overly tight fit, longer belt life, less
bearing wear and more quiet operation will result. Overtight belts can
cause early failure and should be avoided. With high torque a loose
belt may jump teeth upon startup. If such occurs, the tension should
be increased gradually until satisfactory operation is achieved.
V-belt tensioning adjustment can be made using a tension meter or
other type spring scale, using the following procedure. After seating
the belts in the groove and adjusting center distance so as to take up
slack in the belts, further increase the tension until only a slight bow
on the slack side is apparent while the drive is operating under load.
Stop the drive, and using the meter, measure the force necessary to
depress one of the center belts 1/64-inch for every inch of belt span
(see sketch below). For example, a deflection for a 50-inch belt span
is 50/64ths, or 25/32-inch. The amount of force required to deflect the
belt should compare with the deflection forces noted in the chart
below. Also notice for V-belts that deflection forces vary from the
initial run-in values which are greater (reflecting higher run-in
tensioning) to the normal values for after the run-in period.
To properly tension a synchronous belt, place belt on pulleys and
adjust takeup until the belt teeth mesh securely with the pulley
grooves. Measure belt span T . Then tighten belt so that it deflects
1/64-inch for every inch of belt span when a force as specified in the
table below is applied to the top of the belt. For belts wider than two
inches, a metal or wooden strip 3/4 to 1-inch wide should be placed
across the belt between it and the tester to prevent distortion.
Span Le
The following range of deflection forces are normally adequate for
drive installation. Actual installation tension required depends on peak
loads, system rigidity, number of teeth in mesh, etc.
