Ruland Beam Coupling, 9.5mm Outside Diameter, 3mm Bore, 14.3mm Length Coupler

Ruland PCMR10-3-3-A is a four beam coupling with 3mm x 3mm bores, 9.5mm OD, and 14.3mm 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. PCMR10-3-3-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. PCMR10-3-3-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. PCMR10-3-3-A is manufactured in our Marlborough, MA factory under strict controls using proprietary processes.
