The Reich Arcusaflex ACH6NN is a genuine OEM flexible rubber disc drive coupler engineered for dependable power transmission in internal combustion engine and industrial compressor drive systems. As a direct OEM replacement, this coupler restores original equipment performance without modification, guesswork, or compatibility risk.
The ACH6NN utilizes a disc-shaped rubber element that provides highly flexible torsional performance with a linear deflection characteristic. This design allows the coupler to absorb high torsional vibrations and shock loads while simultaneously compensating for major shaft misalignments — protecting bearings, gearboxes, and connected drivetrain components from stress-related wear and premature failure.
The axial plug-in design simplifies installation and allows for ample axial float, making assembly and future servicing straightforward without the need for special tooling. Because this is a genuine OEM Reich part, the ACH6NN meets the exact performance and interface specifications of your equipment.

Why Genuine OEM Matters
Non-OEM couplers may appear similar but often carry material and dimensional variations that compromise vibration absorption, reduce service life, and introduce drivetrain reliability issues. The Reich ACH6NN is manufactured to the same standard as your original equipment — ensuring correct fit, reliable torque transmission, and full compatibility from the moment it’s installed.
