Timing pulleys are a fundamental component in mechanical systems that demand precision and reliability. Timing pulleys are also known as synchronous pulleys and play a critical role in applications ranging from automotive engines to industrial machinery.

Timing belts and pulleys — in order to handle a wide range of loads, speeds and applications at highest possible eficiencies — are made in five stock pitches. Circular pitch (usually referred to as pitch) is a basic consideration in the selection of timing pulleys as with gear and chain drives.

The different types of timing pulleys include: Traditional Timing Pulleys. The traditional timing pulleys are usually made of steel or aluminum. They feature a standard tooth shape and come in a range of sizes and pitches. These pulleys are designed with a flat face that helps reduce noise and wear. Adjustable Timing Pulleys

Timing pulleys have teeth or pockets around the outside diameter of the pulley body. Timing teeth engage holes in the metal belt, while timing pockets engage drive lugs on a belt’s inner circumference. As the name implies, these teeth or pockets are used for timing.

A timing pulley is a cogged or cross-tooth pulley with the belt tooth matching the pulley tooth, much like a chain and sprocket. U.S. Rubber developed the first timing pulleys or synchronous pulleys and belts in the 1940s.

A timing pulley is a pulley that uses a toothed belt to transmit rotational motion between two shafts. It is usually made of metal, but can also be made of plastic or rubber. The belt transmits motion by the engagement of the teeth, which “lock” onto the pulley teeth.

Timing pulleys, bushings, and belts provide low-cost, reliable power transmission between rotating components with changes to speed and torque as needed. MXL pitch (also known as mini extra light pitch) synchronous drive components are ideal for high-speed, low-torque applications.
