The bushes are available with various outer dimensions. For every outer dimension, there are a large number of bore sizes matching several shaft diameters.

Requirements Regarding the Driving Elements
The component that is to be mounted must be in taper version (must have the matching conical bush bore with mounting threads and dismountig bore). Using the taperlock bushing system makes most sense in serial production. For one-off production the use of cylindrical clamping bushes is more economical. These are available in many different versions. But if needed, in our own factory, we can rework driving elements into taper-version, from one-off production.

Available Driving Elements
There are various sprockets, pulleys and couplings in taper version available from stock.

Additional Products
Bolt-on hubs or welding hubs for taperlock bushings enable the easy use of the taper bush system for chain plate wheels or other elements. Alternatively, adaptors for taper bushes can be used to mount a taper lock bush in a cylindrical hole.

Requirements Regarding the Shaft
Cylindrical shaft with a diameter tolerance of +0.05mm / -0.125 mm. The best results are achieved with ISO-tolerance h6. Up to a shaft diameter of 100mm cost-effective drawn shafts with tolerance h9 may also be used.

Application with and without Parallel Key
Due to the high clamping force a parallel key is not necessarily required for medium torques (e.g. with pulleys). If the shaft has a keyway, and no parallel key is used, the keyways of shaft and bush should be mounted with an offset of 180 degrees. For highest torques a shaft with keyway and parallel key must be used.
