Ruland Aluminium Clamp Jaw Coupler 57.2 mm OD, 80 mm Length, Zero Backlash MJC57-16-A

Ruland MJC57-16-A aluminium clamp jaw coupler features a 57.2 mm outside diameter and 80 mm length, optimized for zero backlash mechanical power transmission. Made from lightweight aluminium, this clamp-style coupler hub offers excellent durability and ease of installation. Its three-piece design consists of two aluminium hubs paired with an elastomeric insert known as the spider, which helps absorb misalignment including axial motion, angular, and parallel misalignment. This design enhances coupling reliability and longevity in industrial applications.

The coupler supports a maximum rotational speed of 8000 rpm and has a torque rating of 16 Nm, making it suitable for high-speed and precision applications. It operates reliably within a temperature range from -10°F to 180°F, accommodating various environmental conditions. Standard DIN 912 12.9 M6 screws are provided for secure fastening of the clamp mechanism, ensuring robust assembly strength.

The zero backlash jaw type minimizes vibration and maintains precise mechanical control, which is critical in servo and stepper motor drive systems, encoders, and other precision machinery. This coupler is manufactured in the United States and conforms to ISO9001:2015 quality standards, reflecting high manufacturing excellence and consistency.

Typical industrial use cases for this lightweight aluminium coupler include applications in mechanical power transmission systems, automation equipment, and precision drives found in manufacturing, robotics, and instrumentation industries. Its balanced design helps reduce inertial loads and vibrations at high speeds, improving equipment lifespan and performance.
