Synchronous belt drives. Imperial pitch trapezoidal profile system. Belts and pulleys. | Status: Confirmed, Current

1 Scope This International Standard specifies the principal characteristics of synchronous endless belts and pulleys for use in synchronous endless belt drives1 for mechanical power transmission and where positive indexing or synchronization is required. The principal characteristics includes the following:

1. a) belt nominal tooth dimensions;
2. b) belt length and width dimensions and tolerances;
3. c) belt length-measurement specifications;
4. d) pulley grooves dimensions and tolerances;
5. e) pulley dimensions and tolerances;
6. f) pulley quality specification.
