Ruland Bellows Coupling, 41.3mm Outside Diameter, 20mm Bore, 50.8mm Length Coupler

The Ruland bellows coupling has a 41mm OD, 50.8mm length and 20mm x 14mm 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.
