The ACT6ST Reich Arcusaflex Drive Coupler is a heavy-duty OEM coupling from the Reich ACT series, size class 6 with taper-lock hubs. The taper-lock configuration provides secure, self-centering shaft connections with higher clamping force than keyway bores, suited for the elevated torque demands of large portable compressors and heavy industrial drives.
ACT6 taper-lock couplers serve equipment rated at 300+ CFM in portable compressor applications and comparable power levels in industrial drives. The taper-lock interface is preferred in high-torque applications where conventional keyway connections may be subject to fatigue stress.
Follow the manufacturer’s specific torque sequence for taper-lock hardware installation. Do not reuse worn taper-lock components. Verify alignment before startup.
Stark Industrial Products carries ACT6 taper-lock Arcusaflex couplers for heavy equipment service.
