Ruland Aluminium Set Screw Style Flexible Coupler 12.7 mm OD 3 mm Bore 5.6 mm Length MOST13-3-A

Ruland MOST13-3-A aluminium set screw style flexible coupler with a 12.7 mm outside diameter, 3 mm bore diameter, and a hub length of 5.6 mm is engineered for use in mechanical power transmission and motion control systems. This coupling supports shafts with slight misalignments and provides torque overload protection.

The coupling is manufactured from black anodised aluminium hubs and features a finished bore with no keyway, suitable for precise shaft connections where keyways are not desired. It supports a maximum speed of 4500 rpm, making it applicable in a variety of light industrial and precision motion control applications including stepper and servo motors.

The Oldham coupling design comprises two hubs linked by a centre torque disc, which can absorb torque overloads by breaking cleanly, thereby protecting the connected machinery. The set screw style hubs use one set screw each on 13 mm and 19 mm sizes for secure shaft attachment. Centre discs are replaceable and made from acetal or nylon, allowing ease of maintenance and extended service life.

This coupling accommodates minor misalignments: angular misalignment of up to 0.5°, parallel misalignment of 0.1 mm, and axial misalignment of 0.1 mm, ensuring smooth mechanical operation even with slight shaft deviations.

Compliant with RoHS and REACH standards, this product provides environmentally responsible performance. With manufacturing origin in the United States, it meets high-quality production criteria.
