Rubber Coupling Elements

Rubber coupling elements are flexible inserts that connect or cushion rotating coupling members. Tyre rings, pin bushes, blocks and doughnut forms transmit torque while absorbing shock and torsional vibration, and their compliant construction tolerates limited shaft displacement in heavy industrial drives.

Questions about rubber coupling elements

What should I send to identify rubber coupling elements?

Send coupling type and size, element dimensions, bolt or pin pattern, torque and speed, operating environment. For tyre elements, include bolt pitch circle and bead form; for bushes, include pin and sleeve dimensions. A clear photograph, drawing or readable reference can resolve details that dimensions alone do not show.

How should I select rubber coupling elements?

Choose rubber compound, reinforcement and geometry from torque, shock, misalignment, temperature, oil exposure and coupling design. Confirm the mating parts and operating environment before ordering, since an apparently similar size can use a different profile, material or internal arrangement.
