Ruland Coupling

The Ruland jaw coupling hub has a 51mm OD, 20mm bore, 6mm keyway and 20.8mm length with clamp fastening. This is readily accommodated by any combination of axial motion, angular and parallel misalignment. It comprises of a three-piece design consisting of two aluminium hubs and an elastomeric insert, called the spider. This design allows a highly customizable coupling that easily combines clamp or set screw hubs. Its balanced design reduces vibrations at high speed. This product has a key bore.
