Ruland Aluminium Flexible Coupler 25.4 mm OD, 6 mm Bore, 35.3 mm Length, Finished with No Keyway MJS25-6-A

Ruland MJS25-6-A Aluminium Flexible Coupler offers a robust mechanical power transmission solution with a 25.4 mm outside diameter, 6 mm bore diameter, and a length of 35.3 mm. This finished bore coupling is designed without a keyway, providing a zero backlash curved jaw coupling ideal for balancing torque and alignment in mechanical assemblies.

Constructed from durable aluminium material, the coupling is part of the MJS series known for low to medium torsional rigidity and strength. It features a polyurethane spider insert that effectively damps impulse loads, minimizing shock transmission to motors and sensitive equipment. This design allows for slight angular, axial, and parallel misalignments, making it versatile for industrial applications.

The coupling is rated for a maximum operational speed of 8000 rpm and is electrically isolating, which enhances motor and equipment longevity. Its balanced design supports high bearing loads and moderate inertia, ensuring stable power transmission.

Each hub is sold individually; a complete assembly requires two aluminium hubs and a spider (sold separately). The fail-safe spider snap fit ensures zero backlash and maintains high torque capabilities even in failure scenarios. The coupling meets DIN 911.9 standards and complies with RoHS and REACH regulations, guaranteeing quality and environmental compliance.

This coupling is ideal for usage in industrial machinery, manufacturing equipment, mechanical power transmissions, and other engineering applications requiring reliable, flexible shaft couplings.
