Ruland Coupler 57.2 mm Outside Diameter Elastomer Element Aluminium Hub Zero Backlash MJCC57-30-A

Ruland MJCC57-30-A mechanical power transmission coupler features a 57.2 mm outside diameter elastomer element and lightweight aluminium hubs with a clamp fastening style designed to provide zero backlash torque transmission. The three-piece construction includes two aluminium hubs paired with an elastomeric insert (spider) that allows compensating for axial, angular, and parallel misalignments while maintaining balanced performance at speeds reaching 8000 rpm.

The M6 screw clamp fastening meets DIN 912 12.9 standard for high torque capabilities, ensuring robust mechanical connection. Operating temperature ranges from -10°F to 180°F (-23°C to 82°C), suitable for demanding industrial environments. The jaw coupling design minimizes backlash to reduce wear and enhance system accuracy.

Its elastomer spider insert provides dampening characteristics that improve system performance and extend component service life by reducing vibrations during operation. The aluminium hubs offer low inertia and lightweight construction enabling quick assembly and better dynamic response in motion control applications.

This coupler is ideal for use in stepper motors, servo drives, and encoder systems where precision and durability are critical. Compliance with REACH, RoHS2, and DIN standards certifies this product for industrial applications across mechanical, automation, and power transmission sectors.
