Attribute37Torque ratings are at maximum misalignment.
Attribute38Performance ratings are for guidance only. The user must determine suitability for a particular application.
Attribute39Torque ratings for the couplings are based on the physical limitations/failure point of the machined beams. Under normal/typical conditions the hubs are capable of holding up to the rated torque of the machined beams. In some cases, especially when the smallest standard bores are used or where shafts are undersized, slippage on the shaft is possible below the rated torque of the machined beams. Please consult technical support for more assistance.

Bullet_pointFour beam couplings have higher torque and torsional stiffness than commodity style single beam couplings and are ideal for encoder, tachometer, and other light duty applications. Hardware exceeds DIN 912 12.9 standards for maximum torque capabilities. Ruland beam couplings are carefully made from select North American bar stock in our Marlborough, Massachusetts factory and are RoHS3 and REACH compliant. Manufactured from 7075 aluminum for light weight and low inertia. Smaller bodies than six beam couplings allow them to fit in confined spaces. Zero-backlash and a balanced design for reduced vibration at speeds up to 6,000 RPM.
