FAQ

A taper lock bush is a standardized, keyed mounting system that allows a pulley to be securely fitted to a wide range of shaft diameters. It provides a strong, concentric grip and simplifies installation and removal without needing a custom-bored pulley.

This pulley is designed for SPZ section narrow V-belts. You should select a belt with the 'SPZ' profile designation. The length of the belt will depend on the center distance between your pulleys in your specific application.

The maximum speed depends on the balancing grade, but for standard cast iron pulleys of this size (63 mm diameter), the peripheral speed should generally not exceed 35 m/s. Always consult the manufacturer's technical datasheets for precise operational limits in your specific application.
