The ACH3SN Reich Arcusaflex Drive Coupler is an OEM coupling from the Reich ACH series. The “S” side offers a more secure, self-centering grip that is preferred for higher-torque connections, while the “N” side uses a conventional keyed bore. This configuration is found in various compressor, pump, and industrial drive applications. During installation, follow the specific mounting procedure for each hub type – taper-lock hubs require a defined torque sequence on the locking hardware. Verify alignment after installation.
Available from Stark Industrial Products with expert coupling selection support.
