The BJ-1333-25 Sullair OEM Drive Coupler is a Lord BJ-series coupling specified for Sullair portable air compressor platforms. This coupling provides the engine-to-airend connection in Sullair portables that use Lord BJ couplings as original equipment.
Lord BJ-1333 couplers serve the small-to-mid portable compressor class, with each variant (identified by the number after the dash) matched to a specific compressor model’s torque and vibration requirements. The bonded elastomeric element absorbs diesel engine vibration, protecting the Sullair airend from torsional fatigue during continuous field operation.
The BJ-1333-25 is a direct OEM replacement. Match the exact BJ part number before ordering. Install per Sullair’s alignment procedure.
