FAQ

What is a 1610 taper bush and is it included?

A 1610 taper bush is a standardized mounting component used to fix the pulley to a shaft. It allows for a range of shaft diameters and ensures a strong, concentric grip. The bush itself is not included with the pulley and must be ordered separately based on your specific shaft diameter.

These designations refer to the cross-sectional dimensions of the V-belt and pulley groove. SPZ is the narrowest profile, followed by SPA, SPB, and SPC. It is crucial to match the pulley profile (SPZ) with the correct V-belt profile to ensure proper power transmission and prevent premature wear.

Proper alignment is critical for belt and pulley life. Use a straight edge or laser alignment tool to ensure the pulley is perfectly in line with the driving pulley. Belt tension should be set according to the manufacturer's specifications, using a tension gauge for accuracy. Overtensioning can damage bearings, while under-tensioning leads to slippage and wear.
