Ruland Flexible Coupler 25 mm OD, 10 mm Bore, 35.3 mm Length, Aluminium, No Keyway Bore MJS25-10-A

Ruland MJS25-10-A is a precision engineered flexible coupler designed for mechanical power transmission. It features a 25 mm outside diameter and 10 mm bore diameter with a 35.3 mm length aluminium hub finished with no keyway bore configuration. This design allows for easy installation and reliable mechanical fitment.

The coupler comprises a balanced three-piece assembly that includes two aluminium hubs and an elastic polyurethane spider (sold separately). The elastic spider insert provides damping of impulse loads to reduce shock to motors and sensitive equipment, offering low to medium torsional rigidity and strength with electrical isolation properties.

Constructed from high-quality aluminium, the coupling provides corrosion resistance and lightweight durability. It supports maximum rotational speeds up to 8000 rpm, making it suitable for a wide range of industrial applications including manufacturing, material handling, HVAC systems, and laboratory equipment.

This zero backlash curved jaw design reduces backlash and ensures smooth torque transmission. The snap-fit spider insert allows for high torque capabilities and failsafe operation, allowing the coupler to operate even if the spider element fails. Slight angular, axial, and parallel misalignments during operation are accommodated without compromising performance.

Note that each hub is sold separately; a complete coupling assembly requires two hubs and a spider insert. This modular design allows for customized coupling configurations and easy maintenance.

Standards compliance includes REACH, RoHS, and DIN 91 1.9, and the product is manufactured in the United States. The coupler is highly suitable for industrial machinery, power transmission systems, and precision mechanical assemblies.

It provides electrically isolating coupling and high bearing load capacity with moderate inertia handling. Recommended for applications requiring vibration damping and shock absorption.
