The ACH4WN-Kit is a complete coupling package for the ACH4WN configuration, including both hubs and the elastomeric element. The ACH4 is the heavy-duty variant of the size class 4 coupling, handling higher torque loads than the standard-duty ACT4 series.
The flanged hub on one side connects to engine flywheel housings or equipment flanges, while the keyed bore on the other side mounts to the driven shaft. The complete kit ensures all components are matched, simplifying procurement for scheduled maintenance and equipment rebuilds.
Install per the equipment manufacturer’s alignment and torque specifications. Verify smooth operation before returning to service.
