Electric motors, generators and associated equipment are at risk when an electric current passes through their bearings. This can damage the contact surfaces of rolling elements and raceways in the bearings (electrical erosion) and rapidly degrade the grease.
An additional risk in electric motors and generators comes from high frequency currents caused by the inherent stray capacitance. The risk of damage increases where the application uses a frequency converter.
NSOCOAT bearings are designed to prevent electric current from passing through the bearing. The external surfaces of either their inner or outer ring are coated with an insulating aluminium oxide layer,by applying a sophisticated plasma-spray process for an outstanding quality finish. The solutions are very cost-effective compared with other insulation methods.
More robust than typical deep groove ball bearings, they are highly customizable with the possible combination of many different components. This results in up to 10 000 possible configurations! Find the optimum configuration to deliver the kind of high performance you need – whether that’s exceptional durability, for example, or lower friction.
Designed especially for wind turbine generators, SKF Quiet Running deep groove ball bearings significantly reduce noise levels and structural resonance. They are less sensitive to variable operating conditions, can increase bearing service life and extend relubrication intervals.
