Product Description

An Insulated 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.

Insulated bearings with a coated outer ring

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

Insulated 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.
