The Ruland six beam coupling is engineered for precision in transmitting torque between shafts with misalignment capabilities. Its robust design ensures durability and optimal performance in various mechanical applications.
Machined from a single piece of 7075 aluminium for lightweight and low inertia
Designed with two sets of three spiral cuts to accommodate greater misalignment
Displays a reference mark for easy identification of the larger bore
Complies with RoHS3, REACH, and Conflict Minerals regulations
Meets stringent DIN 912 12.9 standards for maximum torque capabilities
