SKF OK Couplings
Slash connection times for shafts and flanges
An SKF OK Coupling does not require a keyway in the shaft or hub to transfer the torques. This is a major savings and helps avoid shaft stress raisers. They incorporate a thin tapered inner sleeve, designed to fit over the shaft, and a thick outer sleeve, with a taper matching that on the inner sleeve. Oil is injected at high pressure between the mating surfaces and the outer sleeve is driven up the inner sleeve with an integral hydraulic jack. Once correctly positioned, oil pressure is released and the resulting powerful interference fit enables high torques to be transmitted.
