Ruland Aluminium Flexible Coupler 25.4 mm OD, 8 mm Bore, 35.3 mm Length Finished Bore MJS25-8-A

Ruland MJS25-8-A flexible coupler is a high-quality mechanical power transmission component made from aluminium, designed to provide reliable torque transmission in various industrial settings. It features a 25.4 mm outside diameter, an 8 mm bore diameter finished with no keyway, and a length of 35.3 mm. This coupling is engineered as a zero backlash curved jaw type to minimize torque fluctuations and improve equipment longevity.

The coupling assembly consists of two aluminium hubs and an elastic polyurethane spider insert, which provides damping of impulse loads, minimizing shock to connected equipment such as motors and sensitive instrumentation. The spider insert is available in 92 Shore and 98 Shore hardness ratings, enabling users to optimize the balance between vibration dampening and torsional rigidity depending on application needs.

The MJS series coupling delivers electrical isolation, balanced performance for high bearing loads, and capacity to handle moderate inertia. It also accommodates slight angular, axial, and parallel misalignments, ensuring smooth operation in demanding environments. With a maximum speed rating of 8000 rpm, it supports use in various manufacturing, mechanical power transmission, and material handling applications.

This flexible coupler is manufactured in the United States to stringent standards including DIN 911.9, RoHS, and REACH directives, assuring compliance with safety and environmental regulations. The snap fit spider design guarantees zero backlash and a fail-safe operation allowing the coupling to function even if the spider element fails.

Note that the product is supplied as a single hub only; for a complete coupling assembly, two hubs along with a spider are required and sold separately. This modular design facilitates easy maintenance and customization.
