The ACT4UN Reich OEM Drive Coupler is a Reich Arcusaflex coupling element from the ACT4 series with UN hub configuration. This mid-range Arcusaflex coupling provides torsional vibration isolation for industrial compressors, pumps, and mechanically driven equipment.

The ACT4 is a versatile coupling size found in a wide range of industrial installations where moderate torque capacity and compact dimensions are needed. Reich Arcusaflex couplings are selected by equipment designers for their predictable damping characteristics and maintenance-friendly element replacement procedure. The elastomeric element can be changed without moving the connected equipment, which reduces service time significantly compared to solid coupling designs that require shaft separation.

When servicing the ACT4UN, separate the hubs axially, slide out the old element, and inspect both hub profiles for wear or damage. Install the new element with all lobes properly seated and verify that the hubs return to the correct axial spacing specified by Reich.
