Insulated Cylindrical roller bearing NU1012 M/C3VL0241 is one kind of Current Insulated bearings, it consist of Inner Ring with Coated, or outer ring with coating, brass or nylon, Brass cage and steel rollers, the cylindrical roller and raceway of the rings are line contact, so cylindrical roller bearings are the same with spherical roller bearing, tapered roller bearing, thrust roller bearing and the other kinds of roller bearings, they all have larger load capacity than ball bearings, cylindrical roller bearing mainly carry radial load, Small friction between the rollers and the ribs of the rings make the cylindrical roller bearings are suitable for the application which are high speed rotation. There are many different design according to the ribs of the rings, NU, NJ, NUP, N, NF series single row cylindrical roller bearing, Insulated Cylindrical roller bearings focus on used in Electrical Motors.


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



Development of concept of insulated bearing


Product Features of NU1012 M/C3VL0241 Bearings

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.


Two functions in one solution

a bearing function

electrical insulation


• Virtually eliminates premature bearing failures caused by stray electric currents

• Increased machine uptime

• Reduced maintenance costs

• Provide an economical solution when compared with other insulation solutions

• Global availability of a wide assortment
