Product Description

Ruland MJCC57-20-A is a high-performance mechanical power transmission coupler featuring a 57.2 mm outside diameter and an 80 mm overall length. The device consists of a three-piece assembly with two aluminium clamp hubs and an elastomeric spider element that delivers zero backlash and vibration dampening capabilities. This balanced coupling supports maximum speeds up to 8000 rpm and operates reliably within temperature ranges from -10°F to 180°F.

The clamp-style hubs provide a secure fastening, accommodating axial, angular, and parallel misalignments with ease. The elastomer spider insert enhances system performance by minimizing component wear and absorbing shocks during operation.

Manufactured in the United States, the coupling is built to meet DIN 912 12.9 standards using metric hardware (M6 screws), ensuring durability and high torque handling capability. Its lightweight aluminium construction contributes to low inertia, making it an excellent choice for precision motion control in industrial machinery.

Typical applications include stepper motors, servo drives, and encoder setups where high accuracy and system reliability are critical. The zero backlash design allows for precise positioning and motion transfer, making it suitable for demanding mechanical power transmission tasks.

Constructed with aluminium hubs and an elastomer spider insert for flexible coupling. Zero backlash jaw type reduces vibrations and improves mechanical accuracy. Clamp fastening style provides secure and easy installation.

Supports speeds up to 8000 rpm for high-speed applications. Temperature operation range from -10°F to 180°F ensuring versatile performance. Meets DIN 912 12.9 standards with high torque metric hardware. Lightweight aluminium design reduces inertia and enhances system response.

Ideal for stepper and servo motor drives and encoder coupling. Explore more from Ruland Mechanical Power Transmission Couplers for reliable and precision industrial components at EnvMart.
