Ruland 25.4 mm Outer Diameter 12 mm Bore, 33.3 mm Length Aluminium Clamp Style Bellows Coupling Stainless Steel MBC25-12-8-A

Ruland MBC25-12-8-A Aluminium Bellows Coupling features a 25.4 mm outer diameter with bore sizes of 12 mm and 8 mm and a length of 33.3 mm. This flexible coupling is designed with zero backlash and a balanced design that reduces vibration at high speeds up to 10,000 RPM. It combines anodized aluminum hubs and stainless steel bellows allowing flexibility while remaining rigid under torsional loads.

The coupling effectively accommodates misalignment in angular, parallel, and axial directions, ensuring reliable power transmission in mechanical systems. It features a torque rating of 6.8 Nm and an inertia moment of 2.693 x 10⁻⁶ kg/m², making it suitable for demanding stepper and servo motor applications, including precise encoder positioning.

Manufactured under strict quality controls in Marlborough, MA using high-grade solid bar stock sourced exclusively from North America, the MBC25-12-8-A offers durability and performance that meet or exceed DIN 912 12.9, REACH, and RoHS3 compliance.

This coupling’s clamp style hubs and stainless steel bellows are lightweight and robust, providing excellent torsional rigidity while allowing for axial, parallel, and angular misalignments within specified limits. Operating temperature capability ranges from -40°C to 93°C, making it compatible with diverse industrial environments.
