The ACT2.3ST Reich Arcusaflex Drive Coupler is an OEM coupling from the Reich ACT series, size class 2.3 with taper-lock hubs. This is the taper-lock variant of one of the most widely deployed Arcusaflex sizes in the portable compressor market.
The taper-lock configuration on the ACT2.3ST provides a more secure shaft connection than standard keyway bores, with self-centering properties that improve concentricity. This variant is specified by OEM manufacturers for compressor platforms where the taper-lock interface provides the optimal mounting solution for the application’s torque and alignment requirements.
When installing, follow the manufacturer’s specific torque sequence for the locking hardware. Do not reuse worn taper-lock components. Verify alignment before startup.
