Ruland Coupling
The Ruland bellows coupling has a 51mm OD and 58.7mm length with clamp fastening. This clamp is 25mm x 25mm 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.
