The Ruland Bellows Coupling with Keyways is designed for lightweight operation and low inertia, featuring two anodized aluminum hubs and a stainless steel bellows. Engineered with a balanced design, it effectively minimizes vibration even at high speeds of up to 10,000 RPM. The coupling’s thin-walled bellows provide flexibility while maintaining rigidity under torsional loads, allowing for the accommodation of all forms of misalignment, ensuring smooth and precise power transmission.

Hardware is metric and tests beyond DIN 912 12.9 standards for maximum torque capabilities

It is carefully made in our ISO 9001:2015 advanced manufacturing facility

RoHS3, REACH, and conflict minerals compliant
