46587020 Ingersoll Rand OEM Coupling

The 46587020 Ingersoll Rand Drive Coupler is a factory OEM coupling assembly engineered for portable air compressor drivetrains. This coupling connects the diesel or gas engine to the compressor airend through a flexible torsional element, isolating the drivetrain from startup shock and operating vibration while maintaining reliable power transfer under continuous duty.

The flexible element absorbs torsional oscillation and compensates for shaft misalignment, protecting the engine, airend, and connected bearings from the fatigue that untreated vibration causes over time. This design supports smooth, low-maintenance operation with long service life even in the high-cycle, high-vibration environment typical of portable compressor packages.

The 46587020 coupling is used across Ingersoll Rand and Doosan portable air compressor platforms as a direct OEM replacement. Stark Industrial Products ships the 46587020 the same day on in-stock orders. Call us 24/7 at (903) 768-1111 to confirm fit and availability for your unit.
