The ACT4.WN-Kit is a complete coupling package for the ACT4WN configuration, including the flanged hub, keyed hub, and elastomeric element as a matched assembly. The ACT4 size class serves mid-range portable compressors and industrial equipment.
The flanged and keyed hub combination accommodates equipment where the driving and driven shafts have different mounting interfaces. The complete kit provides all matched components in one package for streamlined service and procurement.
The flanged and keyed hubs are not interchangeable – verify correct orientation during installation. Follow the equipment manufacturer’s alignment and torque specifications.
