Taper Lock Sprockets

The TransDrive taper lock sprocket has a split through the taper and flange to provide a locking mechanism on the shaft.

Taper lock sprockets, also known as taper bush and taper fit sprockets are used in a variety of machines. This is a pre-bored and keyed sprocket to match the required shaft and keyway diameters. This is an advantage with faster and easier fitting, better centring and the ability to change bore size without replacing the sprocket.

The TransDrive Taper lock sprockets are available in various sizes.
