6319/C3VL0241 INSOCOAT SKF Electrically Insulated Ball Bearing

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 uptime 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 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 up to 2 000, or even 3 000 V DC, can be supplied on request.

INSOCOAT bearings typically have the external surfaces of the outer ring coated with aluminium oxide. These bearings are identified by the designation suffix VL0241.
