Ruland Aluminium Clamp Style Jaw Flexible Coupler 41.3 mm Outside Diameter, 10 mm Bore, 53 mm Length Finished MJC41-10-A

Ruland MJC41-10-A is an aluminium clamp style jaw flexible coupler designed for mechanical power transmission. It features a 41.3 mm outside diameter with a 10 mm bore size and a finished length of 53 mm. This coupler is finished with no keyway bore, making it suitable for precise shaft connections without keyways.

The clamp style jaw couplings from Ruland are known for their large torque capacity and balanced design. Each coupling requires two aluminium hubs and an elastic polyurethane spider placed between them for complete operation. The spider provides damping of impulse loads, which reduces shock transmitted to motors and sensitive equipment, while minimizing backlash for higher torque capabilities.

The flexible coupling design accommodates slight angular, axial, and parallel misalignments, making it ideal for varied industrial and mechanical applications. The electrically isolating nature of the aluminium hubs helps protect electrical components. This coupling model supports a maximum speed of 8000 rpm, suitable for medium speed machinery.

Ruland couplings come with compliance certifications such as RoHS and REACH and meet the DIN 911.9 standard for mechanical performance and safety. Manufactured in the United States, this product assures reliable quality and performance.

Constructed from aluminium for lightweight durability. Clamp style jaw coupling offers zero backlash and high torque capacity. Use of elastic polyurethane spider dampens impulse loads and shocks. Balanced design suited for high bearing loads and moderate inertia.

Accommodates slight shaft misalignments for versatile applications. Maximum shaft speed rating of 8000 rpm. Complies with RoHS, DIN 911.9, and REACH standards. Made in the United States ensuring superior manufacturing quality.

For a complete coupling assembly, two hubs and an appropriate jaw spider torque disc are required and must be ordered separately. This modular design allows customization of torsional rigidity and damping characteristics based on spider hardness selection (92 Shore for damping, 98 Shore for rigidity). Ruland clamp style jaw Flexible Couplers are widely used in industrial machinery, fluid power systems, and power transmission setups where reliable torque transfer and vibration damping are critical.
