FAQ

What is a 1610 taper bush?

A 1610 taper bush is a standardized mechanical component used to mount pulleys, sprockets, or couplings onto a shaft. It features a tapered outer surface that locks into the pulley’s bore and a straight, keyed inner bore for the shaft, providing a strong, concentric grip when tightened.

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

These designations refer to different cross-sectional sizes of narrow V-belts. SPZ is the smallest (10mm top width), followed by SPA (13mm), SPB (16mm), and SPC (22mm). It is crucial to match the pulley groove profile (SPZ in this case) with the corresponding V-belt type for optimal performance and longevity.

How do I correctly install a V-belt on this pulley?

First, ensure the pulleys are correctly aligned. Loosen the motor mounts to create slack in the drive. Fit the belt over the pulleys without forcing it. Then, move the motor back to apply tension. The correct tension is typically when the belt deflects about 1.5% of the span length under moderate thumb pressure. Finally, tighten all mounting bolts.
