About Maurey Manufacturing
Power Transmission Pulleys, Belts & Coupling Systems
Maurey Manufacturing is a fourth-generation, family-owned company with over 100 years of heritage in mechanical power transmission, evolving from its 1917 founding as a manufacturer of wheel locks and woodworking equipment into the leading producer of precision steel V-pulleys, bushings, and integrated drive systems. The company combines traditional craftsmanship with modern CNC manufacturing to deliver pulleys that withstand demanding industrial environments.
The Maurey Manufacturing product portfolio includes light-duty bored-to-size and bushed sheaves, quick-detachable (QD) style sheaves with removable hubs for convenient shaft changes, timing pulleys and sprockets for synchronous drive applications, variable-speed drives with variable pulley systems, split-steel sheaves for retrofit applications, and complete conveyor belt systems using ContiTech Continental belting.
Product lines span Hi-Q Light Duty Sheaves (fractional to oversized diameters), HQ Ful-Grip Sheaves and Bushings for high-torque transmission, Positive Drive Pulleys and High Torque Drive Sprockets, Hi-Q and Hi-Flex Couplings (rigid and flexible designs), manual and spring-loaded sheaves with adjustable positioning, and ContiTech's complete belt inventory.
Maurey's competitive advantage is the combination of quality materials (high-grade steel), precision CNC grinding, quick-turnaround custom work, and deep stock of standard sizes. The company offers technical consultation on power transmission design, belt selection, and system optimization to maximize efficiency and equipment life.

Frequently asked questions
What's the advantage of QD (quick-detachable) bushings versus fixed-bore sheaves?
QD bushings allow rapid shaft size changes without removing the sheave from the machine—unscrew the QD hub, install on a different motor shaft, and reassemble the sheave. This versatility is invaluable in shops where the same pulley might drive different equipment at different times. Fixed-bore sheaves cost less but require sheave removal and replacement for bore changes.
How do I calculate the correct belt length when connecting two Maurey sheaves?
Use the formula: Belt Length = 2C + 1.57(D1 + D2), where C is center distance and D1/D2 are sheave diameters. If center distance is unknown, rearrange to solve for C given your belt length constraint. Maurey technical support can assist with calculations; incorrect belt length causes improper tension and accelerated wear.
Can I use a variable-speed Maurey drive to replace a fixed single-speed sheave?
Yes, if both sheaves are variable-pitch designs (one driver, one driven) and you have the adjustable motor mounting for tension and speed control. Fixed sheaves cannot be retrofitted with variable drives—you must replace the entire sheave set. Variable drives cost more but enable infinite speed ratios within a range.
What's the maximum horsepower a Maurey Hi-Q pulley can transmit?
HP capacity depends on sheave diameter, width, rpm, and belt type. Small fractional pulleys handle <5 HP; industrial-size pulleys (10"+ diameter) handle 50+ HP. Consult Maurey's capacity tables or contact technical support with your motor HP and desired speed ratio—oversizing reduces belt stress and extends life.
How do I adjust belt tension on a Maurey drive system?
Loosen the motor mounting bolts slightly, then slide the motor away from the sheave (increasing center distance) until belt tension is correct—typically 0.5–1 inch deflection midway between sheaves under light thumb pressure. Retighten motor bolts, and verify tension hasn't changed after a few days of operation (belts settle).
