Ruland 57.2 mm OD 20 mm Bore Finished with No Keyway Aluminium Clamp Style Flexible Coupler MOCT57-20-A

Ruland MOCT57-20-A is a clamp style Flexible Coupler featuring a 57.2 mm outside diameter and a 20 mm bore finished with no keyway. The aluminium hubs are black anodised, providing excellent durability and corrosion resistance suitable for a variety of industrial applications.

This coupling is specifically engineered to accommodate small amounts of axial, angular, and parallel misalignment, making it ideal for precise shaft coupling in light industrial environments, motion control, and automation systems such as servo and stepper motor drives.

The product includes two hubs and one torque disc per assembly. The torque disc, made of acetal or nylon, serves as a torque limiter by breaking cleanly under overload conditions to protect connected machinery.

Its maximum operating speed is 4500 rpm, supporting high-speed operations while maintaining flexibility in assembly. The coupling is secured to the shafts with set screws, with securing arrangements dependent on hub size to ensure a reliable fit.

Certified under RoHS and REACH standards, this coupling offers environmental safety and compliance assurance. It is manufactured in the United States and benefits from rigorous quality controls.
