Shaft to shaft coupling for rotating
equipment
The OK range of shaft to shaft couplings from SKF has been introduced to reduce the time required to connect rotating shafts and flanges in heavy equipment.
A range of shaft to shaft couplings from SKF, a leading knowledge engineering company, has been introduced that can significantly reduce the time required to connect rotating shafts and flanges in heavy equipment, such as turbines, generators, and large gearboxes and motors Called OK couplings, these products provide a simple solution to mounting and dismounting shaft couplings; operations that took hours or even days are reduced to a few simple steps

Gearbox design smashes engineering barriers
Considered a breakthrough in the world of industrial transmissions, a gearbox offers a service life of greater than 50,000 hours - 30,000 more than the industry average.
Packaging improvement prevents bearing damage
A versatile, robust and environmentally friendly packaging solution for the transportation of large-size bearings affords easier and safer handling and superior protection.
The results include increased performance and service life for machinery, and, consequently, decreased maintenance costs.
The couplings incorporate a thin tapered inner sleeve, designed to fit over the shaft, and a thick outer sleeve, with a reverse taper matching that on the inner sleeve.
Conventional mineral oil is injected at high pressure between the mating surfaces and the outer sleeve is driven up the inner sleeve by using an integral hydraulic 'jack'.
Once correctly positioned, oil pressure is released and the resulting powerful interference fit enables high torques to be transmitted.
Unlike with conventional coupling processes, no shaft machining, keyways, or taper and thrust rings are necessary, and the use of heat is also no longer required.
Included in the range are OKF Couplings, for attaching a flange to a shaft end, and OKCK Couplings, for use in wind turbines.
All unit lengths and internal and external diameters can be supplied to customer specifications.
A range of dedicated installation tools are also available. Request a free brochure from SKF UK ...
