Ruland Aluminium Zero Backlash Jaw Coupler 41.3 mm OD, 53 mm Length, Elastomer Element MJCC41-12-A

Ruland MJCC41-12-A is a precision-engineered aluminium jaw coupling designed for zero backlash performance in mechanical power transmission applications. Featuring a 41.3 mm outside diameter and 53 mm hub length, this flexible coupling incorporates an elastomeric spider element to provide excellent torsional flexibility and vibration dampening.

The clamp style, three-piece design assembles two durable aluminium hubs with a resilient elastomer insert, allowing for high customization with various bore sizes and keyway options. This coupling supports speeds up to 8000 RPM and transmits torque up to 4.6 Nm, making it suitable for industrial, manufacturing, automation, and HVAC machinery requiring reliable rotational motion transfer.

The coupling hub is machined from North American bar stock and assembled using metric hardware that exceeds DIN 912 12.9 standards, affording exceptional durability and performance at elevated torque levels. The elastomer element offers three durometer hardness options for tailoring coupling characteristics to specific applications.

Operating temperature range from -10°F to 180°F enables functionality in both cold and warm industrial environments. The zero backlash jaw type eliminates lost motion for accurate positioning and efficient mechanical power transmission.

Manufactured in the United States under strict quality controls, the MJCC41-12-A coupling delivers precision and reliability required in harsh industrial conditions. It is ideal for use in mechanical systems requiring vibration reduction, torsional stiffness, and ease of assembly.
