FSMR19-5-5-A, Ruland Beam Coupling, 19mm Outside Diameter, 5mm Bore, 31.8mm Length Coupler

Ruland FSMR19-5-5-A is a six beam coupling with 5mm 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. FSMR19-5-5-A is zero-backlash and has a balanced design for reduced vibration at high speeds of up to 6,000 RPM. All hardware is metric. FSMR19-5-5-A is made from 7075 aluminium for lightweight and low inertia. It is machined from bar stock that is sourced exclusively from North American mills. FSMR19-5-5-A is manufactured in our Marlborough, MA factory under strict controls using proprietary processes.
