Rexnord G4CMR500 500.CMR.CPLG CB SD Thomas Disc Coupling complete unit. This 500 size CMR type coupling features a stainless steel disc pack for high torque transmission and misalignment accommodation. Suitable for industrial power transmission applications requiring zero backlash and maintenance-free operation.

The Rexnord Thomas CMR coupling is ideal for heavy-duty, slow to medium speed applications, where high-starting torque, shock loads, torque reversals or continuous alternating torques are present. The open lug type center member provides ample clearance for assembly while minimizing the space required for coupling installations. The CMR coupling is available with a variety of coatings as well as compatible with a range of hub sizes. Typical applications include engine and motor driven reciprocating compressors, Motor and turbine driven pumps, fans, synchronized rollers, wire feeders, blowers or any application driven through a flywheel adapter. CMR couplings are compatible with a range of hub sizes and available in 21 sizes ranging from 162 through 1550. The Thomas CMR Coupling is engineered to accomodate torque loads up to 3,124,000 lb-in and shaft diameters up to 16.0 inches.
