The ACT2.6ST Reich Arcusaflex Drive Coupler is an OEM coupling from the Reich ACT series, size class 2.6 with taper-lock hubs. The taper-lock mounting provides a secure, self-centering shaft connection that delivers higher clamping force than standard keyway bores, suited for applications with elevated torque or where keyway fatigue is a concern.
ACT2.6 couplers serve mid-range portable compressors, industrial pump systems, and engine-driven equipment. The taper-lock configuration on this coupling is specified by OEM manufacturers including Atlas Copco and Ingersoll Rand for select compressor platforms where the taper-lock interface provides the optimal shaft connection.
When installing a taper-lock coupler, follow the manufacturer’s specific torque sequence for the locking hardware to achieve proper clamping force. Do not reuse worn taper-lock components. Verify alignment after hub installation before startup.
