BJ-1163-8 Lord OEM Drive Coupler

The BJ-1163-8 is a Lord OEM drive coupler designed for heavy-duty industrial and drilling rig applications. This coupling is part of Lord’s BJ-series product line, which is engineered for high-torque power transmission where torsional damping and shock load protection are critical.

Lord BJ-series couplers are specified as original equipment in several heavy machinery platforms, including DM-series rotary drilling rigs (DM-45, DM-50, DM-L) used in mining and quarry operations. These couplings use a robust elastomeric or metallic element construction to absorb the severe torsional loads generated during drilling, protecting engines, gearboxes, and driven equipment from damaging vibration and impact forces.

The BJ-1163-8 is sized for medium-to-heavy industrial drivelines. When replacing, reference the original installation dimensions including hub bore, bolt circle, and hub-to-hub gap. Alignment is critical in drilling rig applications – follow the equipment manufacturer’s procedure and verify with dial indicators before returning the machine to service.
