The 02250069-226 Sullair OEM Center Bushing is a mounting component for the drive coupling assembly in Sullair portable air compressors. This bushing provides the precision shaft-to-hub interface within the coupling, ensuring concentricity and proper power transmission.
In Sullair’s coupling assemblies, the center bushing sits between the coupling hub and the shaft, providing a tight, balanced fit. A worn or damaged bushing allows play in the connection, introducing vibration that the elastomeric coupling element cannot adequately absorb. This leads to accelerated element wear, increased bearing loads, and potential mechanical seal issues in the compressor airend.
The 02250069-226 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 Sullair’s installation procedure. Verify that the coupling assembly runs true after installation by checking for abnormal vibration.
