Rexnord 20R10P-50.00C-1.875S Elastomeric Coupling

Rexnord 20R10P-50.00C-1.875S Elastomeric Coupling is a Rexnord elastomeric shaft coupling designed to connect two rotating shafts with a 1.875-inch bore. The model designation places it in the 20R family and identifies the bore size as 1.875 inches, with the elastomeric element housed between two hubs to transmit torque while accommodating minor shaft misalignment and end float. This coupling is used in power-transmission assemblies where a compact, low-maintenance link is preferred and where vibration and shock need to be damped during operation. The 1-7/8" bore specification ensures compatibility with shafts of that diameter, supporting common industrial drive configurations such as pumps, fans, conveyors, and other equipment that require reliable torque transfer without lubrication. For complete torque ratings, installation details, and compatible hub configurations, consult Rexnord's official product documentation for the 20R elastomeric family and this exact part number.
