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.

What is the difference between SPZ, SPA, and SPB profiles?

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.

How do I ensure proper alignment and tension for this pulley?

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.
