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. The standard assortment of INSOCOAT bearings listed here constitutes the most commonly used sizes and variants of. Single row deep groove ball bearings, Single row cylindrical roller bearings
In addition to the standard assortment, SKF can supply special INSOCOAT bearings and bearing units with complex ring geometries, such as:
• Four-point contact ball bearings
• Flanged tapered roller bearings
• Tapered roller bearing units (TBU)
• Traction motor bearing units
