INSOCOAT Bearings models

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, INSOCOAT bearings can improve reliability and increase machine up time by virtually eliminating the problem of electrical erosion.

An INSOCOAT bearing is a standard bearing that has the external surfaces of its inner or outer ring plasma-sprayed with an 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 up to 2 000, or even 3 000 V DC, can be supplied on request.
