Insocoat Bearings Electrically Insulated Cylindrical Roller Bearing Nu211 Ecm/C3vl0241 for Electric Motors
Product Description
Product Features of Insulation Bearings
An INSOCOAT bearing is a standard bearing that has the external surfaces of its inner or outer ring plasma-sprayed with an aluminium oxide to form a coating. The coating is sealed with a resin to protect against the conductive effects of water and moisture.
The basic coating can withstand voltages up to 1 000 V DC. However, coatings to withstand voltages more than 3 000 V DC, can be supplied on request.
INSOCOAT bearings with a coated outer ring
INSOCOAT bearings typically have the external surfaces of the outer ring coated with aluminium oxide. These bearings are identified by the designation suffix VL0241.
INSOCOAT bearings that have the external surfaces 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.

Detailed Photos
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.
INSOCOAT bearings:
- are designed to prevent electric current from passing through the bearing
- have the external surfaces of either their inner or outer ring coated with an insulating aluminium oxide layer, by applying a sophisticated plasma-spray process for an outstanding quality finish
- are a very cost-effective solution compared with other insulation methods
Bearing features
- Protection against electrical erosion
With insulating properties integrated into the bearing, INSOCOAT bearings can improve reliability and increase machine uptime by virtually eliminating the problem of electrical erosion.
- High electrical resistance
The aluminium oxide coating provides a minimum electrical resistance of and can withstand voltages up to 3 000 V DC.
- Consistent electrical performance
Plasma-spray coatings are normally hygroscopic and, therefore, vulnerable to penetration caused by condensation. To protect against this effect, INSOCOAT bearings are treated with a unique sealant.
