Tyre Couplings

A highly elastic coupling which can operate with a high degree of misalignment supplied with taper lock or pilot bore

Tyre couplings consist of 2 cast iron flanges which are mounted onto the shaft by means of taper bushes.

Between the flanges sits a torsionally flexible elastic tyre which can accommodate high shaft misalignment (up to 4° ) as well as limited axial and parallel misalignments without imposing excessive loads on the adjacent bearings, whilst absorbing shock loads and vibration in the powertrain.

Easy to inspect visually and replace without effort.

Tyre couplings are suitable for use from -50C to +50C

Selection of Tyre Couplings

1. Design power = motor power x service factor

2. Select suitable coupling based on shaft speed and power from the table below

3. Check that this coupling can accommodate taper bushes big enough for your shaft, if not select a larger coupling.
