INSOCOAT SKF BEARINGS

Electric motors, generators and associated equipment are at risk when an electric current passes through a bearing. This can damage the contact surfaces of rolling elements and raceways in the bearing (electrical erosion) and rapidly degrade the grease.

Categories: ,

Description

An additional risk in electric motors and generators comes from high frequency currents due to the inherent stray capacitance. The risk of damage increases if the application uses a frequency converter.

SKF INSOCOAT bearings are designed to prevent current from passing through the bearing. The bearings are a very cost-effective solution compared with other insulation methods. By integrating the insulating properties into the bearing, SKF INSOCOAT bearings can improve reliability and increase machine uptime by virtually eliminating the problem of electrical erosion.

INSOCOAT bearings with a coated outer ring are identified by the designation suffix VL2071

INSOCOAT bearings typically have the outside diameter and side faces of the outer ring coated with aluminium-oxide. These bearings are identified by the designation suffix VL0241.

INSOCOAT bearings with a coated inner ring

INSOCOAT bearings that have the bore and side faces of the inner ring coated are identified by the designation suffix VL2071. These bearings provide enhanced protection against high frequency electric currents due to the smaller coated surface area of the inner ring compared to the outer ring.
