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

• Regreasable traction motor bearing unit
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.
