The A21764D-251-SK Cornell OEM Bushing is a mounting bushing used in Cornell Pump Company drive coupling assemblies. This bushing serves as the shaft-to-hub interface component, providing a precise, secure fit between the coupling hub and the pump or driver shaft.

In Cornell pump coupling systems, the bushing ensures concentricity between the coupling hub and shaft. A worn or damaged bushing allows play in the hub-to-shaft connection, which introduces vibration that the elastomeric coupling element was not designed to absorb. This can lead to accelerated element wear, increased bearing loads, and mechanical seal problems.

The A21764D-251-SK is a direct OEM replacement. When replacing the bushing, clean the shaft surface and hub bore thoroughly, inspect for scoring or dimensional wear, and follow Cornell’s installation procedure for the bushing type. Verify that the coupling assembly runs true after installation by checking runout with a dial indicator.
