Ruland Coupling


The Ruland bellows coupling has a 51mm OD, 58.7mm length and 20mm x 16mm 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.
