This International Standard specifies the principal characteristics of synchronous pulleys for use in synchronous endless belt drives for mechanical power transmission and where positive indexing or synchronization may be required. The principal characteristics include a) tooth dimensions and tolerances b) pulley dimensions and tolerances; c) quality specification. As far dimensions are concerned, the pulleys specified in this International Standard, for pitch code MXL, may be used interchangeably with the belts specified in ISO 5296-1 and ISO 5296-2.
