HRC 80 Series

The 80 series allows the maximum angular, radial and axial misalignment. The inner hub of the HRC coupling must be supported by the gearbox, generator, or pump input shaft for this series.

HRC 81 Series

The 81 series allows angular misalignment. A spherical bearing for support of the inner hub of the HRC is mounted to the flywheel.

HRC 82 Series

The 82 series is designed for installation with a pneumatic clutch.
The existing pneumatic clutch spacer is removed and replaced with a HRC coupling without moving the engine, gearbox, generator, or pump foundations. The coupling inner hub is supported on tapered roller bearings, so angular and radial runout must be compensated for by the pneumatic clutch glands.
