The 57565103 Ingersoll Rand OEM Drive Coupler is an OEM coupling for Ingersoll Rand portable compressor and equipment platforms. This coupling uses a Reich Arcusaflex ACH-series heavy-duty design, handling the torque demands of larger IR portable compressors and industrial drives.
ACH-class couplers on IR equipment serve the heavier end of the portable compressor range and related industrial machinery. The heavy-duty elastomeric element absorbs substantial torsional forces from large diesel engines, protecting airend bearings, gearbox components, and seals from vibration-induced fatigue during sustained field operation.
The 57565103 is a direct OEM replacement. Follow IR’s service procedure with proper alignment verification during installation.
