High Precision Electric Motor Bearings 6311 M/C3VL0241 For Rail Vehicles

Electrically Insulated Bearing 6311 M/C3VL0241 Bearing 55×120×29mm Used In Rail Vehicles

Electrically Insulated Bearing 6311 M/C3VL0241 is Deep Groove Ball Bearing design. its dimension is 55×120×29mm, it has the same dimension and the same design with normal chrome steel 6310 bearings. but the most different is 6311M/C3VL0241 bearing with Aluminium Oxide Coating. the coating can Electrical Resistance Voltages up to 3000 V DC.

Electrically Insulated Bearing 6311 M/C3VL0241 bearings are not only Electrically Insulated deep groove ball bearing but also Electrically Insulated Cylindrical Roller Bearing, Electrically Insulated Tapered Roller Bearing, Electrically Thrust Roller Bearing and the other type Normal or Non-Standard Electrically Insulated Rolling Bearings. they are the same dimension , same cage, same elements and the other data with normal chrome steel rolling bearing, just the different coating on the surface of the inner ring or outer ring of the Rolling Bearing.

Electric Insulated bearing 6311 M/C3VL0241 has an electrically insulating coat on the outer ring(suffix VL0241) or on the inner ring(suffix VL2071), respectively. insulated bearings are widely used in Electric Motors, Generator, Alternator. There is 100μm thick coating on the surface of the inner or outer ring, the into coat bearing can bear voltages up to 1000V DC, insulated & into coat bearing can keep away from moisture and humidity, it can carry radial and axial loads in both directions.

Principle bearing types for traction motor applications

• Cylindrical roller bearings

• Electrically insulated cylindrical roller bearings

• Electrically insulated deep groove ball bearings

• Hybrid cylindrical roller bearings with ceramic rollers

• Hybrid deep groove ball bearings with ceramic balls

• Traction motor bearing units based on cylindrical roller bearings and deep groove ball bearings

• Sensors traction motor bearing unit

• Regreasable traction motor bearing unit

Electric Insulated Bearing 6311 M/C3VL0241 provide a bearing function and electrical insulation virtually eliminates premature bearing failure caused by stray electric currents, the electrical insulated bearing can reduce the number of failures and improve the machine uptime, reduce the cost of maintenace.
