BJ-1333-21 Ingersoll Rand Coupling Kit

The BJ-1333-21 Ingersoll Rand Drive Coupler Kit is a complete OEM coupling assembly for Ingersoll Rand portable diesel-driven air compressors. This kit ships with the coupling element and the center hub bushing, supplying the matched components needed for a full coupler service in one part number rather than sourcing each piece separately.

The coupler forms the connection between the diesel engine output shaft and the compressor airend input shaft, transmitting full operational torque while absorbing the firing-pulse vibration produced by the diesel engine. This isolation protects the airend bearings, shaft seals, and downstream drivetrain components from the accelerated wear that develops when uncontrolled torsional spikes are allowed to pass through the assembly.

The BJ-1333-21 is specified across the Ingersoll Rand portable air compressor lineup. Ordering the complete kit shortens repair turnaround for rental fleets, sandblasting contractors, and field service operations where compressor uptime drives revenue.
