The ACT3SN Reich Arcusaflex Drive Coupler Kit is a complete coupling package for the ACT3SN configuration. This kit includes the taper-lock “S” hub, standard keyway “N” hub, and elastomeric element as a matched assembly ready for installation.
The ACT3 size class serves portable compressors and light industrial equipment. The “SN” kit configuration is specified for equipment where one shaft uses a taper-lock connection and the other uses a standard keyway. Having the complete kit on hand enables faster coupling replacements during scheduled maintenance or emergency service calls.
Follow the specific installation procedure for the taper-lock “S” hub, which requires a defined torque sequence on the locking hardware. Verify alignment after both hubs are installed.
Available from Stark Industrial Products for compressor and equipment service operations.
