The ACT2.3NN Reich Arcusaflex Drive Coupler is an OEM coupling from the Reich ACT series, size class 2.3 with standard keyway bores on both hubs. This is one of the most commonly specified Arcusaflex couplings in the portable air compressor market, used across platforms from multiple OEM manufacturers.
The ACT2.3 size class serves small-to-mid range portable compressors and industrial equipment. Standard keyway bores on both sides make this configuration compatible with conventional keyed shaft connections on both the engine and driven equipment. The elastomeric element dampens diesel engine vibration, protecting compressor airends, pump bearings, and other driven components from torsional fatigue.
The ACT2.3NN is a direct replacement for equipment originally fitted with this coupling. Do not substitute with an ACH2.3NN, as the ACT and ACH series have different torque ratings. Install per the equipment manufacturer’s specifications with proper alignment verification.
