Taper-Bush Pulleys

Taper-bush pulleys are grooved belt wheels with a conical hub seat for a removable split bush. Tightening the bush screws clamps it onto the shaft and into the pulley, simplifying bore adaptation and removal while maintaining a concentric mechanical connection for industrial belt drives.

Questions about taper-bush pulleys

What should I send to identify taper-bush pulleys?

Send belt profile, pulley diameter and grooves, bush series, shaft bore and keyway, drive speed. Quote pulley and split-bush details separately, including bore, because one pulley body accepts a limited family of bush sizes. A clear photograph, drawing or readable reference can resolve details that dimensions alone do not show.

How should I select taper-bush pulleys?

Coordinate pulley grooves, bush taper, finished bore, keyway, shaft fit and balance with the complete belt drive. Confirm the mating parts and operating environment before ordering, since an apparently similar size can use a different profile, material or internal arrangement.
