Ruland Coupling

The Ruland bellows coupling has a 33mm OD and 42.9mm length with clamp fastening. This clamp is 8mm x 8mm bore coupling. This is readily accommodated by any combination of axial motion, angular and parallel misalignment. It comprises of two anodized aluminium hubs and stainless steel bellows. This bellow is able to flex while remaining rigid under torsional loads. Its balanced design reduces vibrations at high speed.
