Ruland Beam Coupling, 19.1mm Outside Diameter, 5 mm, 8 mm Bore, 31.8mm Length Flexible Beam Coupling [FSMR19-8-5-A]; 591-380

The Ruland Set screw style six beam coupling with 8mm x 5mm bores, 19.1mm OD, and 31.8mm length. 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. Its 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
