FCR20-8-8-A RUL

Ruland six beam couplings are zero-backlash and have a balanced design for reduced vibration at high speeds up to 6,000 RPM. This F-series beam coupling is machined from a single piece of aluminum and features two sets of three spiral cuts allowing for higher torque capacity, lower windup, and larger body sizes than four or single beam couplings. It is clamp style and has 0.500" x 0.500" bores, 1.250" OD, and 1.750" length. The use of 7075 aluminum creates a lightweight low inertia coupling that is best suited for encoders and light duty power transmission applications such as coupling a servo motor to a lead screw. It has Ruland's proprietary Nypatch® coating on hardware to prevent them from coming loose during operation. Nypatch® also allows for even seating of the screw, repeated screw installations, prevents galling, and maintains high holding power. Hardware is metric and tests beyond DIN 912 12.9 standards for maximum torque capabilities. This six beam coupling is RoHS and REACH compliant. It is made from bar stock sourced exclusively from North American mills and manufactured in Ruland's Marlborough, Massachusetts factory under strict controls using proprietary processes.
