250031-872 Sullair OEM Drive Coupler

The 250031-872 Sullair OEM Drive Coupler is a factory coupling for Sullair rotary screw air compressors. This drive coupler connects the prime mover to the Sullair airend, managing torsional loads and vibration in continuous-duty compressor operation.

Sullair uses the 250031-series catalog designation for coupling components across various compressor platforms. The drive coupler in a Sullair compressor is critical to the health of both the motor and airend, as it absorbs the mechanical energy that would otherwise travel through the shaft connection and damage precision bearings and seals. Sullair compressors in industrial plants accumulate substantial running hours, and the coupling element should be inspected during annual or semi-annual maintenance to catch degradation before it causes a forced outage.

The 250031-872 drops directly into the factory mounting on compatible Sullair models. Follow lockout/tagout before service, remove the old element, inspect hubs, and verify alignment before installing the replacement.
