Easy Installation - Over 500 Sizes – Taper Bushes
Taper bushes allow a single pulley or sprocket etc. to be quickly adapted to suit multiple shaft sizes whilst avoiding the time and cost of machining the bores and keyways. The bush has a slit from the inside bore to the outside diameter and a counter half slit on the opposite side which allows the taper bush to flex and tighten around the shaft when it is screwed into the taper bore. A keyway groove is also machined into the bush allowing a keyway to be used for anything above a low torque application. Over 500 metric and imperial bore sizes are available with millions of bushes in use around the world today. Manufactured from a high-quality close grain cast iron or C45 medium carbon steel for thin walled bushes, the Challenge bush offers a well proven and flexible shaft fixing method designed to fit a large range of Challenge and third-party products.
