The ACT2.3NT Reich Arcusaflex Drive Coupler is an OEM coupling from the Reich ACT series, size class 2.3. This coupling serves portable air compressors and light industrial equipment in the small-to-mid power range.
The ACT2.3 size class is one of the most widely deployed Arcusaflex sizes in the compressor industry, found across portable compressor platforms from multiple OEM manufacturers. The elastomeric element absorbs engine vibration while the hub configuration provides the correct shaft interface for the target equipment. Proper coupler selection is critical – each variant is matched to specific shaft dimensions and torque requirements.
The ACT2.3NT is a direct replacement for equipment originally fitted with this exact model. Do not interchange with other ACT2.3 variants, as the hub configurations differ. Install per the equipment manufacturer’s specifications.
