Ruland Beam Coupling, 16mm Outside Diameter, 5mm Bore, 20.3mm Length Coupler

Ruland PCMR16-5-5-A is a four beam coupling with 5mm x 5mm bores, 15.9mm OD, and 20.3mm 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. PCMR16-5-5-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. PCMR16-5-5-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. PCMR16-5-5-A is manufactured in our Marlborough, MA factory under strict controls using proprietary processes.
