INSOCOAT Deep Groove Ball Bearings

INSOCOAT Deep Groove Ball 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.

Features and benefits:

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 200 MΩ 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.
