HRC coupling inserts

HRC coupling inserts are elastic elements placed between the jaws of the two coupling hubs. They transmit torque, damp vibrations and shocks, and also protect the motor and machine bearings against the effects of slight shaft misalignment.

HRC coupling inserts - restoring performance without buying new hubs

Replacing the insert restores the coupling's performance without buying new hubs and usually without removing them from the shafts. An insert of a given size fits all HRC hubs of that size - both pilot bore and Taper-Lock. Timely replacement prevents direct contact between the hub jaws and damage to them.

Elastic elements for HRC shaft couplings in all sizes

Inserts for HRC couplings in the sizes of the entire system. The size is given in the product name - it must be the same as the size of the hubs.

When to replace an HRC coupling insert - questions and answers

When should the insert be replaced?

The signs are knocking at start-up and when the direction of rotation changes, noticeable circumferential play between the hubs, and cracks or missing material on the insert.
