Synchronous Timing Belt Pulley and Flange Dimensions Table per ANSI / RMA IP-24, ISO 5299 and IS 9804.

Synchronous timing gears are used with toothed timing belts to transmit rotary or linear motion. Timing gears and belts are commonly used with stepper motors for precision driven movement. The principle benefit is the ability to separate the motor and load without needing rigid complex gear trains. Timing gear-belt chains can be low-backlash, and are tolerant of shaft misalignment and mechanical imprecision.
