The B-Flex coupling consists of a set of resilient "barrel" shaped bushes. These bushes provide varying torsional stiffness characteristics.

Torsional stiffness is the property of flexible coupling which enables the coupling to absorb shocks & vibrations. If torsional stiffness of a coupling varies according to loading level, coupling can give better performance in shock & vibration absorption

RB-Flex coupling has a specially designed barrel shaped bush. Due to its peculiar shape, at light loads, torque is transmitted through line of a contact of mating parts giving less torsional stiffness. As load goes on increasing area of the contact also increases, hence coupling gives more torsional stiffness. Thus varying torsional stiffness is achieved in B-Flex coupling.
