BJ-1333-55 Ingersoll Rand OEM Drive Coupler

The BJ-1333-55 is an Ingersoll Rand OEM drive coupler from Lord’s BJ coupling series. This coupling is specified for use in Ingersoll Rand portable air compressors including models in the P105WJD through P375 and VHP825WCU range.

Lord BJ-series couplings are designed for engine-driven equipment where torsional damping and misalignment compensation are essential. In portable compressor applications, the BJ-1333-55 absorbs the firing-pulse vibration from the diesel engine, preventing it from transmitting into the airend and downstream components. This protects bearings, seals, and shaft surfaces from the accelerated wear that uncontrolled vibration causes.

Install per standard Lord coupling procedures with careful attention to shaft alignment and hub spacing.
