Ruland, 57.2 mm OD, 17 mm Bore, 80 mm Length Keyed Bore Flexible Coupling

The Ruland Clamp Zero-Backlash Jaw Coupling Hub is a component in a three-piece design consisting of two aluminum hubs and an elastomeric insert called the spider. It creates a lightweight, low inertia coupling capable of speeds up to 8,000 RPM. This design allows for a highly customizable coupling that easily combines clamp or set screw hubs with inch, metric, keyed, and keyless bores.

Balanced design for reduced vibration at high speeds
