Product Description
Ruland MJCC51-12-A Aluminium Zero Backlash Clamp Jaw Coupler is engineered for precise and reliable mechanical power transmission. This flexible coupling features a 50.8 mm outside diameter and 61 mm length, composed of two aluminium hubs and an elastomeric spider element providing vibration dampening and zero backlash performance.
The clamp style design ensures easy installation and secure fitment with M5 screws, compatible with DIN 912 12.9 standards. The coupling supports a maximum speed of 8000 rpm and transmits torque up to 9.5 Nm, suitable for high-performance applications including servo and stepper motor drives, encoder connections, and other precision motion systems.
It is designed to operate reliably across temperatures from -10°F to 180°F, making it suitable for industrial environments facing varying thermal conditions. The elastomer element enhances system performance by absorbing shocks and minimizing wear on connected components, thereby extending machinery life.
The MJCC51-12-A series coupling is RoHS2 and REACH compliant, ensuring it meets environmental and safety regulations. Finished to ISO9001:2015 quality management standards, this coupling combines lightweight design and low inertia for efficient rotational dynamics.
Applications include industrial machinery, automation equipment, robotics, and manufacturing processes requiring precise shaft alignment and torque transmission. This coupling’s zero backlash jaw type ensures accuracy in motion transfer while being adaptable to axial, angular, and radial misalignment.
Durable aluminium hubs and elastomer spider increase reliability and system longevity. Clamp fastening with metric hardware complies with DIN standards for optimal torque handling. Capable of speeds up to 8000 rpm with minimal vibration.
Wide temperature tolerance supports diverse industrial environments. Environmentally compliant with RoHS2 and REACH directives. Lightweight construction reduces mechanical inertia for responsive control. Versatile use in stepper and servo drives, encoders, and precision machinery.
