Ruland Beam Coupling, 32mm Outside Diameter, 12mm Bore, 38.1mm Length Coupler / 1864131

Ruland PCMR32-12-12-A is a four beam coupling with 12mm x 12mm bores, 31.8mm OD, and 38.1mm length. It is machined from a single piece of material and feature two sets of two spiral cuts. This gives it higher torque capacity, lower windup, and larger body sizes than single beam couplings. PCMR32-12-12-A is well suited for applications such as encoders that require high positioning accuracy. This four beam spiral coupling is zero-backlash and has a balanced design for reduced vibration at high speeds of up to 6,000 RPM. All hardware is metric. PCMR32-12-12-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. PCMR32-12-12-A is manufactured in our Marlborough, MA factory under strict controls using proprietary processes.
