Ruland Aluminium Clamp Style Jaw Flexible Coupler 25.4 mm OD, 6 mm Bore, 11.9 mm Length Finished with No Keyway MJC25-6-A

Ruland MJC25-6-A Aluminium Clamp Style Jaw Flexible Coupler features a 25.4 mm outside diameter, 6 mm bore diameter, and 11.9 mm length finished without keyway bore. It is made from durable aluminium and designed to meet DIN 91 1.9 standards, RoHS, and REACH compliance. This coupling is ideal for mechanical power transmission applications requiring low to medium torsional rigidity and strength.

The clamp style jaw coupling is a three-piece design that includes two aluminium hubs and an elastic polyurethane spider that provides excellent damping of impulse loads. The snap fit spider ensures zero backlash and high torque capacity, minimizing shock transfer to motors and connected equipment.

The coupling suits high bearing loads and moderate inertia scenarios while electrically isolating the motor from driven equipment. It accommodates slight misalignments in angular, axial, and parallel directions.

To form a complete coupling assembly, two hubs and a jaw spider torque disc are required, sold separately. The 92 Shore spider is recommended for superior dampening characteristics whereas the 98 Shore spider offers enhanced torsional rigidity.

This flexible coupling is widely used in industrial environments such as manufacturing, HVAC systems, fluid power machinery, and construction equipment where reliable power transmission is critical.

Manufactured using high-quality aluminium for strength and lightweight construction. Clamp style jaw design provides zero backlash and balanced operation. Supports up to 8000 rpm maximum speed operation. Allows electrical isolation to protect sensitive equipment.

Provides damping to reduce shock loads via polyurethane spider insert. Accommodates minor misalignments, reducing wear and maintenance. Complete coupling requires two hubs and a jaw spider (sold separately). Origin: United States.
