7MC3 6311 M C3 VL0241 J20AA Current Insulating Bearings for Traction motor

Insulated deep groove ball bearing is a general term for bearings that can prevent the passage of electric current and the bearings themselves have insulating properties. In the past few years, Sweden's Insulated deep groove ball bearing may be the vast majority of end-users' choice, based on the expensive price of brand bearings, TFL company independently developed an electrically insulated bearings, we use a special spraying process, in the outer surface of the bearing spraying high-quality laminating, laminating and the substrate bonding force is strong, insulating performance is good, you can avoid the induced current on the bearings of the galvanic corrosion effect to prevent the current on the lubricating grease and the rolling elements, raceways, damage, improve the service life of the bearings. It can prevent the damage caused by electric current to grease, rolling body and raceway, and improve the service life of the bearings. Insulated deep groove ball bearing Application fields: Power industry: wind turbine, hydro generator, thermal generator. Railroad industry: used in locomotives, etc. Machinery and metallurgical industry: high-power frequency conversion motor with insulated bearings: used in cranes, textile machines, printing machines, iron making equipment, steel making equipment, rolling equipment, cutting equipment, coking equipment, smelting equipment and so on. Mining Machinery Industry: Insulated bearings for high-power high-voltage motors: used in mining machines, coal separators, coal washers, crushers, ball mills, grinding mills, sand mills, etc. Petrochemical industry: Insulated bearings for high-power explosion-proof motors: used in compressors, etc.
