Ruland PCMR19-3-3-SS is a clamp style four beam coupling with 3mm x 3mm bores, 19.1mm OD, and 22.9mm length. It is machined from a single piece of material and features two sets of two spiral cuts. This gives it higher torque capacity, lower windup, and larger body sizes than single beam couplings. PCMR19-3-3-SS is zero-backlash and has a balanced design for reduced vibration at high speeds of up to 6,000 RPM. 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 and tests beyond DIN 912 12.9 standards for maximum torque capabilities.
PCMR19-3-3-SS is made from 303 stainless steel for increased torque capacity. It is machined from bar stock that is sourced exclusively from North American mills and RoHS3 and REACH compliant. PCMR19-3-3-SS is manufactured in our Marlborough, MA factory under strict controls using proprietary processes.
