ACT2.3WN Reich OEM Drive Coupler

The ACT2.3WN Reich Arcusaflex Drive Coupler is an OEM coupling from the Reich ACT series, size class 2.3. This coupling is specified in portable air compressors and industrial pump drives where a flanged hub on one side and a standard keyed bore on the other accommodates the equipment’s shaft configuration.

ACT2.3 couplers are among the most widely used Arcusaflex sizes in the portable compressor industry, serving machines in the small-to-mid power range. The elastomeric element absorbs engine vibration while the specific hub arrangement provides the correct interface for each side of the drivetrain. These couplers are found in compressor platforms from Sullair, Pioneer, and other manufacturers.

The ACT2.3WN is a direct replacement for equipment originally fitted with this exact model. The two hub sides are different and not interchangeable – verify orientation during installation. Follow the equipment manufacturer’s alignment and torque specifications.
