BJ-1333-21 Ingersoll Rand OEM Drive Coupler

The BJ-1333-21 Ingersoll Rand OEM Drive Coupler is a Lord BJ-series coupling specified for Ingersoll Rand portable air compressor platforms. This coupling provides the torsionally flexible connection between the diesel engine and compressor airend in select IR portable models.

Lord BJ couplers are designed for engine-driven equipment and use a bonded elastomeric element to absorb the firing-pulse vibration from diesel engines. In IR portable compressors, this vibration isolation protects the airend bearings and seals from the accelerated wear that uncontrolled vibration causes over time.

The BJ-1333-21 is a direct OEM replacement. Install per IR’s service procedure with careful attention to shaft alignment and hub spacing.
