02250103-559 Sullair OEM Drive Coupler

The 02250103-559 Sullair OEM Drive Coupler is an OEM taper-lock bushing for the drive coupling assembly in Sullair portable air compressors. This component provides the shaft-to-hub interface within the coupling, securing the coupling hub concentrically on the compressor shaft.

In Sullair’s coupling assemblies, the taper-lock bushing ensures a tight, balanced connection between the hub and shaft. A worn bushing allows play in the connection, introducing vibration that accelerates wear on the coupling element and downstream components. Replacing the bushing restores the precision fit needed for proper coupling operation.

The 02250103-559 is a direct OEM replacement. When replacing, clean the shaft surface and hub bore, inspect for scoring or dimensional wear, and follow Sullair’s installation torque procedure for the taper-lock hardware.
