Reich Drive Couplers - Same-Day Shipping

Reich is a German manufacturer of high-performance flexible drive couplers used in industrial air compressors, drilling rigs, and other heavy equipment. The Reich Arcusaflex line is the OEM standard on rotary screw compressors from manufacturers including Ingersoll Rand, Doosan, Sullair, Grimmer Schmidt, and Atlas Copco.

Stark Industrial stocks the most-requested Reich coupler sizes for same-day shipping from our Quitman, Texas warehouse. When a coupler fails the compressor stops producing air, and downtime adds up fast. We answer the phone 24/7 at (903) 768-1111 to help match your part and get it on a truck the same day when possible.

Identifying the right Reich coupler

Reich Arcusaflex coupler part numbers typically start with letters that identify the series and configuration, followed by a size code. Examples include ACT4SN, AC2.4NN, ACH6.1ST, and ACT3WT. The fastest way to confirm a match is the part number stamped on the existing coupler. If the stamp is worn or missing, we can cross-reference using your equipment make, model, and serial number.

Reich coupler series we stock

The Arcusaflex flexible element coupler series accommodates angular, parallel, and axial misalignment while damping torsional vibration. Common configurations include ACT (taper-lock and bolt-on hubs), ACH (hub-style), and AC (compact). Sizes range from small portable compressor couplers up to large industrial rotary screw applications.
