Electrically Insulated 6320 M/C3VL0241 deep groove ball bearings have deep, uninterrupted raceway grooves. These raceway grooves have a close osculation with the balls, enabling the bearings to accommodate radial loads and axial loads in both directions.

Electrically Insulated 6320 M/C3VL0241 deep groove ball bearings are available open or capped (with seals or shields). Open bearings that are also available capped may have recesses in the outer ring.

Sealing solutions

The most popular sizes of Electrically Insulated 6320 M/C3VL0241 deep groove ball bearings can be obtained (supplied) capped with a seal or shield on one or both sides.

Selection guidelines for different sealing solutions under various operating conditions are listed in technical catalogues.


Electrically Insulated 6320 M/C3VL0241 Bearings with shields are primarily intended for applications where the inner ring rotates.

Shields are fitted in the outer ring and do not make contact with the inner ring, but form a narrow gap with it. Shields are made of sheet steel.

Depending on the bearing design, series and size, XRB supplies shields in different designs. Shields identified by the designation suffix Z typically have an extension in the shield bore to form a long, narrow gap with the land of the inner ring shoulder. Some shields do not have the extension.

The Electrically Insulated Bearing adopts the special spraying process, spraying the high quality coating on the outer surface of the bearing, Strong adhesion between film and substrate, Good insulation performance, avoiding the electric corrosion effect of the induced current on the bearing, Prevent current from damage for grease, rolling elements and raceways, Improve the service life of bearings . The process is constantly being improved. Among Electrically Insulated Bearing, there is a 100 μm thick coating on the outer or inner ring surface that can withstand voltages up to 1000 V DC.
