ACT5WN Reich Arcusaflex OEM Drive Coupler

The Reich Arcusaflex ACT5WN 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 ACT5WN features a disc-shaped rubber element that delivers highly flexible torsional performance with a linear deflection characteristic. This design allows the coupler to absorb high torsional vibrations and shock loads while compensating for major shaft misalignments — protecting bearings, gearboxes, and connected drivetrain components from stress-related wear and premature failure.

Equipped with a taper bush hub design, the ACT5WN delivers a shrink-fit-like, backlash-free connection to the shaft after assembly — eliminating the need for special tooling during installation or removal. The axial plug-in facility provides ample axial float, making servicing straightforward in the field. Because this is a genuine OEM Reich Arcusaflex part, the ACT5WN 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 Arcusaflex ACT5WN 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.
