Ruland Coupling

The Ruland jaw coupling hub has a 57mm OD, 25mm bore and 28.7mm 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.
