Ruland FSMR-SS is a set screw style six beam coupling.

It is machined from a single piece of material and features two sets of three spiral cuts. This gives it higher torque capacity, lower windup, and larger body sizes than single or four beam couplings and allows for use in light duty power transmission applications such as coupling a servo motor to a lead screw.

FSMR-SS is zero-backlash and has a balanced design for reduced vibration at high speeds of up to 6,000 RPM.

All hardware is metric and tests beyond DIN 912 12.9 standards for maximum torque capabilities.

FSMR-SS is made from 303 stainless steel for increased torque capacity. It is machined from bar stock that is sourced exclusively from North American mills and RoHS3 and REACH compliant.

FSMR-SS is manufactured in our Marlborough, MA factory under strict controls using proprietary processes.
