Ruland Aluminium Clamp Style Flexible Coupler 15 mm OD, 3 mm Bore, 21.8 mm Length MJC15-3-A

Ruland MJC15-3-A is a high-precision aluminium clamp style flexible coupler featuring a 15 mm outer diameter, 3 mm bore size, and a 21.8 mm length. This mechanical power transmission component is designed to provide zero-backlash performance by integrating two aluminium hubs and an elastomeric spider insert in a three-piece assembly. The lightweight, low inertia design makes it suitable for high-speed applications up to 8000 RPM.

Made from 2024-T351 aluminium bar, the coupler combines strength and reduced weight, supporting operation within a temperature range from -23°C to 82°C. It includes metric hardware compliant with standards such as DIN 912 12.9, ensuring reliable and secure clamping with M2 screws. The design allows flexibility and customization by combining clamp hubs with varied bore options, keys, and keyless variants.

This coupling is ideal for industrial, manufacturing, HVAC, and mechanical machinery applications where vibration reduction and precise torque transmission are critical. The balanced design reduces vibrations during high-speed rotation, enhancing machine longevity and operational accuracy.

Manufactured exclusively in the United States under proprietary processes, the MJC15-3-A model upholds rigorous quality standards supported by certifications like RoHS3 and REACH, ensuring environmental and safety compliance.

Lightweight aluminium construction with clamp style mounting. Three-piece zero-backlash jaw coupling design. Capable of speeds up to 8000 RPM with balanced performance. Operates efficiently within -23°C to 82°C temperature range.
