Product Description

Electrically insulated bearing is the general name of bearings that can prevent current from passing through and have insulating properties. Its insulation performance usually adopts international advanced technology to process a layer of alumina coating on the bearing outer ring or inner ring to withstand DC voltage. It is generally divided into inner ring coated insulated bearing and outer ring coated insulated bearing. Its basic coating can withstand voltages up to 1000 VDC. ZYS offers 500-3000v DC coated insulated that caters cutomers' varied requirements.

Available design: Deep groove ball bearing and cylindrical roller bearing.
