New Product: Tapered-shaft servocouplings

The BK4 tapered-shaft servocouplings are designed to prevent stress on shaft bearings of mounted motor frames.

A stainless-steel bellows in the coupling lets it compensate for slight misalignment in motor mounting with zero backlash and a high level of torsional stiffness. The coupling’s output, configured with a removable clamping bushing, permits access to the inner face of the tapered bore for tightening onto the tapered shaft. The bushing can be bored to any English or metric shaft diameter.
