Ruland Aluminium Clamp Style Jaw Coupler 19.1 mm OD, 5 mm Bore, 27.2 mm Length MJC19-5-A

Ruland MJC19-5-A Aluminium Clamp Style Jaw Coupler is a high-performance component engineered for mechanical power transmission applications. This clamp style jaw coupling includes an aluminium hub with a finished bore of 5 mm diameter, an outside diameter of 19.1 mm, and an overall length of 27.2 mm. It is specifically designed without a keyway bore, offering flexibility in coupling assembly.

The coupling is capable of operating at a maximum speed of 8000 rpm, suited for various industrial uses such as manufacturing, mechanical machinery, and power transmission systems. The coupling consists of two aluminium hubs and a polyurethane spider element that serves as an elastic insert, providing damping of impulse loads and minimizing shocks to connected equipment.

The polyurethane spider insert comes in different hardness grades, allowing customization of damping and torsional rigidity characteristics. The snap-fit spider mechanism ensures zero backlash and a fail-safe design that maintains operation even if the spider element fails. This coupling accommodates slight angular, axial, and parallel misalignments while maintaining a balanced design for high bearing loads and moderate inertia.

Compliant with RoHS, REACH, and DIN 91 1.9 standards, this coupling is manufactured in the United States with quality assurance. Ideal for use in industrial power transmission, mechanical systems, and automation environments.

Constructed from durable aluminium material ensuring lightweight and corrosion resistance. Features a 5 mm bore diameter with a 19.1 mm outside diameter and 27.2 mm length for precision fit. Maximum rotational speed rated up to 8000 rpm for efficient power transmission.

Finished bore type with no keyway for flexible coupling applications. Designed as a clamp style jaw coupling requiring two hubs and a jaw spider for assembly. Polyurethane spider inserts provide reduced impulse loads and protect motors from shock.

Zero backlash design with snap fit spider ensuring high torque capabilities and fail-safe operation. Suitable for accommodating slight angular, axial, and parallel misalignments. Complies with RoHS, REACH standards and DIN 91 1.9 certification.
