Training Module #7Product Line - Pulleys and Bushings

Types of Pulleys/Sheaves/Sprockets

Classical QD PulleysHigh-quality cast iron heavy duty pulleys for classical (A,B,C,D) V-belts. Standardized QD bushings.


QD BushingsStandardized for interchangeability. Tapered and fully split through bore length for equivalent of interference fit.


Durapower Pulleys -Bushed TypeCast iron, for all types of light-duty and FHP applications using 3L, 4L, 5L, A and B section V-belts. Bushing interchanges with similar competitive types.


Durapower Pulleys -Fixed Bore TypeCast iron, bored and keywayed to fit popular shaft sizes. For light duty use with 3L, 4L, 5L, A and B section V-belts.


Durapower Pulleys -Adjustable DiameterRugged cast iron, two-piece threaded assembly allows adjustment of pitch diameter. Combination grooves for use with 3L, 4L, 5L, A and B section V-belts.


RPP Panther SprocketsConstructed from highest quality materials and designed specifically for use with RPP Panther belts. The sprocket teeth are made to mesh and conform exactly to those of the belt, resulting in a drive which functions as a precision gear system.


RPP SprocketsPrecision companion to RPP belts on high torque synchronous drives. Available in plain bore or QD bushed types in 8M, 14M and 20M pitches.


Synchro-Cog Timing PulleysFor perfect mating with timing belts on synchronous drives. Available in plain bore or QD bushed types for pitches XL through XXH.


Power-Wedge QD PulleysHigh capacity cast iron pulleys for use with narrow (3V, 5V, 8V) V-belts. Standardized QD bushings.

• Typical PN 36PTH8-12 is a 36 Groove, 8M Pitch, 12 MM wide sprocket. Takes SH Bushing.

RPP Sprockets

• For RPP Plus Belts (5M, 8M, 14M, 20M)

• Cataloged in differing widths depending on Pitch


• Typical PN P40-5M-25 is a 40 Groove, 5M Pitch sprocket that is 25mm wide. Takes a JA Bushing

Synchro-Cog Timing Pulleys

• For Synchro-Cog Timing Belts (XL,L,H,XH,XXH)

• Cataloged in Std Belt Widths in Bushed or MPB*

• Catalog specifies correct QD Bushing for each size starting with a Q. Parts with M are MPB*.

• Typical PN Q18L050 is 18 Groove, L Pitch, ½” wide and takes a JA Bushing.

*MPB = Minimum Plain Bore

Minimum Plain Bore (MPB)

•MPB Sprockets or Sheaves do not require a bushing.

•They are stocked in a specific bore size such as 3/8” or ½”

•They can be drilled or bored out to whatever diameter the customer requires (Maximum size is defined in catalog).

•Customer can do on his own or we can have it done.

•Example: M17H150 is stocked with a ¾” bore but can be bored out to a maximum of 1-1/4”

Belt/Sheave or Sprocket Combinations

Which Belts Run in Which Type?•Classical QD Pulleys: Gold Ribbon Cog-Belts,

Super II V-Belts, Super Blue Ribbon V-Belts, Double Angle V-Belts, Super Vee-Bands, Gold Ribbon Cog-Bands, Connector Belting, Thoro-Twist V-Belting, Dry Can Belting.

• Note: FHP Durapower, Durapower II and XDV, (4L and 5L) will also run in Classical Pulleys since they are similar to “A” and “B” profile Classicals, but generally run in Durapower FHP type Pulleys.

•Durapower Pulleys (bushed, fixed bore and adjustable): Durapower FHP, XDV and GPL


Which Belts Run in Which Type?

•Power-Wedge QD Pulleys: Power-Wedge Cog-Belts, Super Power-Wedge V-Belts, Wedge-Band Raw Edge Cog-Bands, Wedge-Band Wrap Type Banded V-Belts, Wedge-Band Chipper Drive V-Belts.

•Note: Specific Sheaves/Pulleys exist for Variable Speed V-Belts and for V-Ribbed Belts, but they are made-to-order, non-catalogued, non-stock parts.


Which Belts Run in Which Type?

•Synchro-Cog Timing Pulleys: Synchro-Cog Timing Belts (XL, L, H, XH, XXH), Synchro-Cog Dual Timing Belts, Synchro-Cog Long Length Timing Belting (XL, L, H).
