FAQ

Question?

What is the difference between pitch diameter (106mm) and outside diameter?

The pitch diameter (106mm) is the effective diameter where the V-belt’s neutral axis runs, used for speed ratio calculations. The outside diameter is slightly larger and is the overall physical dimension of the pulley.

Question?

Is the 1610 taper lock bush included with this pulley?

This listing is for the pulley only. The required 1610 taper lock bush, which determines the shaft bore size, must be purchased separately.

Question?

What is the maximum speed rating for this SPZ106-1 pulley?

The maximum permissible speed depends on the balancing quality. For standard cast iron pulleys like this, the peripheral speed should generally not exceed 30 m/s. Always consult the manufacturer’s technical data for your specific application.
