Ruland Mechanical Clamp Style Jaw Coupler, 25.4 mm Outside Diameter, 10 mm Bore, 11.9 mm Length, Aluminium MJC25-10-A

Ruland MJC25-10-A Mechanical Clamp Style Jaw Coupler is engineered with precision for industrial mechanical power transmission applications. This aluminium clamp-style coupling features a finished bore without a keyway, measuring 10 mm bore diameter, 25.4 mm outside diameter, and 11.9 mm length, supporting maximum speeds up to 8000 rpm.

The coupling design incorporates two aluminium hubs combined with an elastic polyurethane spider insert that provides damping of impulse loads and protects sensitive motors and equipment from shock. The polyurethane spider is offered in two hardness levels: 92 Shore for enhanced dampening and 98 Shore for superior torsional rigidity.

This coupling accommodates slight angular, axial, and parallel shaft misalignments while electrically isolating the connected components. Its balanced design is suitable for high bearing loads and moderate inertia applications commonly found in industrial machinery, manufacturing equipment, and fluid power systems.

The fail-safe design allows continued operation even if the spider insert element fails, ensuring safety and reliability in demanding environments. Please note that a complete coupling assembly requires two hubs and one torque spider, which must be ordered separately.

Conforming to RoHS, REACH, and DIN 91 1.9 standards, this coupling meets stringent safety and environmental requirements. It is made in the United States, reflecting high manufacturing quality.

This product is ideal for use in industrial machinery, manufacturing, mechanical drives, and fluid power applications requiring precise torque transmission with minimal backlash and vibration damping.

Clamp style jaw coupling with large torque capacity and balanced design. Aluminium hubs with polyurethane spider insert for shock absorption. Accommodates misalignments and electrically isolates connected components. Maximum speed rating of 8000 rpm for high-performance use.

Complies with RoHS, REACH, and DIN 91 1.9 standards.

To complete the assembly, purchase two hubs and the appropriate spider torque disc separately. Explore EnvMart’s mechanical power transmission categories for complementary coupling components and accessories.
