Specification and design
SKF's involvement in a project can begin in the specification stages, working in conjunction with classification agencies. The knowledge gained through SKF's applied research and worldwide experience contributes to better application solutions.
SKF has contributed to advanced propulsion systems and has redesigned electromechanical solutions to replace hydraulic systems in certain applications. To help OEMs optimize equipment designs while they are still in the prototype stage, SKF engineers use proprietary design software that acts as a "virtual test rig."
Quality products
Supported by a highly efficient global distribution network, SKF is able to deliver critical components by request, wherever, and whenever they are needed. These include everything from bearings and couplings, seals and lubricants to complete units.
Mounting and alignment
SKF mounting and alignment solutions are helping OEMs and shipyards cut maintenance costs by boosting machine reliability, service life, and safety. SKF provides a range of precision bearing and coupling mounting and dismounting services, plus shaft alignment and geometric alignment procedures.
Requirements
SKF remote monitoring and analysis services comply with marine agency classification guidelines, so they can help maximize vessel uptime by streamlining classification and inspection processes. These certified, proven SKF services are supported by an extensive range of condition monitoring tools and technology.
From basic bearing maintenance procedures and training to advanced root cause bearing failure analysis, SKF offers a range of maintenance engineering and consulting services to boost asset uptime.

OK couplings
When using the OK couplings for shaft connections, advantage is taken of the powerful oil injection method.
Preparation of the shaft is simple. No keyways to machine, no taper and no thrust ring. When mounting the OK coupling, a thin inner sleeve with a tapered outer diameter slides onto the shaft. A thick outer sleeve with a matching tapered inner surface fits onto the inner sleeve. Ordinary mineral oil is then injected between the sleeves. A built-in hydraulic jack drives the outer sleeve up the taper of the inner sleeve.
When the outer sleeve has reached its final position an interference fit is created – just as if the outer sleeve had been heated and shrunk on. But no heat is required, and the coupling can be removed as easily as it was mounted.
This powerful use of friction enables the OK coupling to transmit torque and axial loads over the entire area of the shaft. There are no stress raisers at the keyway. And no fretting when high shock or reversing loads exist.
Very large couplings, which previously could only be shrunk on after heating, can now be assembled cold with the OK method.
