Electrically Insulated Bearing 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.

 

Feature of Cylindrical Roller Bearing

1. The rollers and raceway of inner ring and outer ring are in line contact or repair line contact, this design can make the bearing have large carry capacity. So Cylindrical roller bearing are suitable for heavy load and impact load.

2. Low friction coefficient, suitable for high speed, its limited speed are closed to deep groove ball bearing.

3. N and NU series Cylindrical roller bearing can move in axial direction, so they can accommodate to the changes in the relative position of the shaft and the housing due to thermal expansion or mounting errors.

4. High standard for the machining of shaft or seat holes, Relatively skew for the axial of the outer ring should be control strictly. So the Contact stress concentration can be avoid.

The outer ring and inner ring of Cylindrical Roller Bearing are separatable, the design are easy installation and removal.


Development of concept of insulated bearing



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

• Sensorised traction motor bearing unit

• Regreasable traction motor bearing unit


Product Features

1. High insulation properties

To prevent electric corrosion in bearings, a highly productive aluminum ceramic coating material is used to coat the outer ring, and by combining optimized additives, insulation performance is improved by about tenfold.

2. Improved durability

· Optimizing bearing elements improves film impact resistance by a factor of 3x.

· Optimized ceramic coating materials makes for excellent heat dissipation.


Product Benefits

The new product is designed to improve the reliability of motors in general industrial machinery, thereby contributing to the greater adoption of inverter motors.
