Ruland Aluminium Jaw Coupler, 33.3 mm Outside Diameter, 8 mm Bore, 44.5 mm Length, Maximum Speed 8000 rpm MJS33-8-A

Ruland MJS33-8-A aluminium jaw coupler features a 33.3 mm outside diameter, 8 mm bore diameter, and 44.5 mm length, engineered for mechanical power transmission in industrial and manufacturing environments. It is designed to handle maximum rotational speeds of 8000 rpm while providing durable and lightweight performance due to its aluminium construction.

This three-piece flexible coupling consists of two aluminium hubs and an elastic polyurethane spider element. The spider, ordered separately, comes in two hardness levels (92 and 98 Shore) allowing customization between optimal damping of impulse loads and enhanced torsional rigidity. This reduces shock to motors and sensitive equipment while maintaining zero backlash for precise torque transmission.

The finished bore with no keyway allows for secure and precise fitting of shafts. This coupling design effectively accommodates slight angular, axial, and parallel misalignments, making it ideal for systems requiring electrical isolation and moderate inertia handling.

Its balanced construction supports high bearing loads and is ideal for industrial machinery requiring shock absorption and reliable torque transfer. The fail-safe feature ensures the coupler continues to operate safely even if the spider element fails, enhancing system reliability.

For complete assembly, two hubs and the appropriate spider must be procured; this product listing includes only one hub. Common applications include mechanical power transmission in manufacturing, automation systems, and motor shaft coupling for industrial equipment and robotics.

Manufactured from durable aluminium ensuring longevity and strength. Designed for high-speed applications with maximum 8000 rpm rating. Polyurethane spider provides damping and reduces mechanical shock. Zero backlash design for accurate torque transmission.

Accommodates misalignments in motor and drive systems. Electrical isolation suited to sensitive equipment protection. Balanced design supports high bearing loads with moderate inertia. Fail-safe operation continues if spider element fails.

Single hub supply; full coupling requires two hubs and spider. Explore more mechanical power transmission solutions and flexible couplers at EnvMart for your industrial machinery needs.
