Ruland Aluminium Clamp Style Jaw Flexible Coupler 41.3 mm OD, 12mm Bore, 53 mm Length MJC41-12-A

Ruland MJC41-12-A is a high-quality aluminium clamp style jaw flexible coupler with a 41.3 mm outside diameter, 12 mm bore diameter, and 53 mm length. Designed for reliable mechanical power transmission, this coupling assembly is suited to applications requiring zero backlash and shock damping.

The clamp style jaw coupling features a balanced design providing excellent torque capacity and minimal vibration. The aluminium hubs offer strength while being lightweight and corrosion resistant.

This coupling accommodates slight angular, axial, and parallel misalignments, making it suitable for dynamic machinery with varying shaft alignments. It supports speeds up to 8000 rpm, enabling use in high-speed industrial equipment.

The coupling requires two hubs and a polyurethane jaw spider (torque disk) that fits securely between the hubs. The spiders come in two hardness levels (92 Shore for damping, 98 Shore for torsional rigidity), allowing customization of coupling performance. Assembly parts are ordered separately.

Key standards met include REACH, RoHS, and DIN 91 1.9, reflecting compliance with environmental and safety regulations. The bore is finished without a keyway, providing an electrically isolating solution for protecting motors and sensitive devices.

This product is manufactured in the United States and is ideal for industrial, laboratory, manufacturing, and fluid power applications where flexible yet precise mechanical power transmission couplings are needed.
