ACT4.9SN Reich OEM Drive Coupler

The ACT4.9SN Reich Arcusaflex Drive Coupler is an OEM coupling from the Reich ACT series, size class 4.9. This coupling serves portable air compressor platforms including Ingersoll Rand and Doosan models where this specific Arcusaflex size is specified as original equipment.

The ACT4.9 provides the torque capacity needed for mid-range portable compressors while delivering effective torsional damping between the diesel engine and compressor airend. When the coupling element wears, operators notice increased frame vibration, drivetrain noise, and reduced compressor performance – all signals that the element needs replacement.

The ACT4.9SN is a direct replacement for equipment originally specified with this coupling. Verify the exact Arcusaflex model number before ordering. Install per the compressor manufacturer’s alignment procedure.

Stark Industrial Products stocks ACT4.9 Arcusaflex couplers for portable compressor service.
