FAQ

The specific bore type (e.g., pilot bore, taper lock bush) is not specified and should be confirmed or machined to your shaft requirements. This is a common practice for standard pulleys.

The pitch diameter (112mm) is the effective diameter used for calculating speed ratios, located at the neutral axis of the belt. The outside diameter is slightly larger (approx. 116mm for this model) and is the overall physical dimension of the pulley.

Standard cast iron pulleys like this are generally balanced for typical motor speeds (up to 3000 RPM). For very high-speed or precision applications, dynamic balancing may be required.
