42HE-242 Bowex OEM Drive Coupler

The 42HE-242 is a Bowex HE-series drive coupler used in portable air compressors and industrial equipment. This curved-jaw coupling uses an elastomeric spider element to transmit torque between interlocking jaw profiles while providing torsional damping and misalignment compensation.

The 42HE-242 is specified as original equipment in various compressor and industrial platforms from Kaeser and other manufacturers. The compact jaw design suits driveline layouts where a disc-style coupling would not fit. The spider element is the wear component – inspect at service intervals and replace when wear, cracking, or deformation reduces the tight jaw engagement needed for smooth operation.

During replacement, inspect both jaw halves for profile wear. Always replace the spider element during coupling service. Align per the equipment manufacturer’s specifications.
