Ruland Flexible Clamp Style Oldham Coupling, 50.8 mm Outside Diameter, 20 mm Bore, 20.8 mm Hub Length MOCT51-20-A

Ruland MOCT51-20-A flexible clamp style Oldham coupling is engineered for reliable mechanical power transmission in industrial and motion control systems. This coupling features a 20 mm bore diameter, a 50.8 mm outside diameter, and a 20.8 mm hub length to accommodate shafts that require slight axial and angular misalignments. Its clamp-style hubs are crafted from black anodised aluminium, providing durability and resistance to corrosion.

The coupling operates efficiently up to a maximum speed of 4500 rpm, making it suitable for applications involving stepper or servo motors. The three-piece design includes two hubs connected by a centre torque disc made from acetal or nylon. This centre disc functions as a torque limiter that will break cleanly under overload conditions, thereby protecting connected machinery from damage.

The bore is finished with no keyway, allowing smooth shaft insertion and simpler assembly. The hubs are secured with set screws - smaller 13 mm and 19 mm hubs have one set screw each, while larger 33 mm, 35 mm, and 41 mm hubs employ two set screws positioned 90° apart for secure fastening.

This product complies with rigorous environmental and safety standards including RoHS and REACH, assuring users of its safe use and environmentally responsible manufacturing. Made in the United States, it reflects quality craftsmanship and precision engineering.

Applications include light industrial machinery, mechanical power transmission, and motion control environments requiring flexible couplings capable of handling minor shaft misalignments.

Constructed from durable anodised aluminium for enhanced strength. Clamp style design allows easy installation and removal. Torque limiting centre disc protects machines from overload damage. Supports angular, parallel, and axial shaft misalignments.

Suitable for high-speed applications up to 4500 rpm. Complies with RoHS and REACH environmental standards. Explore similar mechanical power transmission solutions in the Flexible Coupler category at EnvMart for advanced motion control and industrial applications.
