Product Details

Ruland Coupling

The Ruland bellows coupling has a 25mm OD, 33.3mm length and 12mm x 10mm bore with clamp fastening. This is readily accommodated by any combination of axial motion, angular and parallel misalignment. It is comprised of two anodized aluminium hubs and a stainless steel bellows. This bellow is able to flex while remaining rigid under torsional loads. Its balanced design reduces vibrations at high speed.
