The ACT2NN Reich Arcusaflex Drive Coupler is an OEM coupling from the Reich ACT series, size class 2 with standard keyway bores on both hubs. This is the smallest standard size in the ACT range, serving light-duty portable compressors, small pump drives, and compact industrial equipment.
ACT2 couplers are specified in smaller portable compressor platforms and light industrial drives where the torque requirements are moderate. Despite being the smallest ACT size, the coupling still provides effective torsional damping that protects driven equipment from engine vibration. These couplers are common in compact diesel-driven equipment across construction and industrial applications.
The ACT2NN is a direct replacement for equipment originally fitted with this coupling. Install per the equipment manufacturer’s alignment specifications. Inspect the coupling at regular service intervals and replace when cracking or deformation of the elastomer is visible.
Available from Stark Industrial Products for light-duty compressor and equipment service.
