Ruland Aluminium Clamp Style Jaw Flexible Coupler 19.1 mm OD 8 mm Bore 27.2 mm Length MJC19-8-A

Ruland MJC19-8-A aluminium clamp style jaw flexible coupler offers a reliable mechanical power transmission solution with a 19.1 mm outside diameter, 8 mm bore diameter, and 27.2 mm overall length. Designed for industrial machinery, this coupler provides a balanced design that supports high bearing loads and moderate inertia while accommodating slight angular, axial, and parallel misalignments.

The clamp style jaw coupling consists of two aluminium hubs and an elastic polyurethane spider (torque disc) which must be sourced separately to complete the assembly. The spider elements are available in multiple hardness levels providing the choice between optimal damping or torsional rigidity.

This coupling operates at a maximum speed of 8,000 rpm and electrically isolates connected shafts, protecting sensitive motor equipment from shocks and vibrations. The finish bore without keyway offers a smooth, interference fit with shafts.

The coupling meets DIN 911.9, REACH, and RoHS standards, ensuring chemical and environmental compliance. Made in the United States, it is suitable for applications in mechanical power transmission, fluid power systems, and industrial automation.

Durable aluminium construction for lightweight strength. Clamp style design provides easy installation and adjustment. Zero backlash curved jaw design minimizes torque losses. Polyurethane spider ensures shock damping and vibration reduction.

Balanced for high-speed operational stability. Electrically isolating properties protect motor and equipment. Suitable for medium to low torsional rigidity applications. Two hubs and one spider needed per complete coupling assembly (sold separately).
