High quality Factory supply OEM & ODM Ceramic insulated ball bearings NSK NTN KOYO NKE for Moto
Product Features
1.Alumina-based ceramic coating material plasma sprayed to ensure bonding to the bearing steel
2.Coating sealed with special acrylic resin
3.Bearings produced from ultra clean steel for extended fatigue life
4.High-grade balls for operation at high speeds
5.Super finished raceways
6.Open type, with C3 radial internal clearance
Applications
Typical applications of the insulated ball bearings in traction motor protection. Potential cases are:
case 1: where electric current could flow from the housing to the shaft. In this case all bearings have to be electrically insulated
case 2: for electric current flow inside the rotor, normally caused by asymmetrical electric motors. Here protection of only one side of the bearing arrangement is necessary. Mainly the smaller bearing, situated on the non-drive side, is selected for electrical insulation
case 3: in wheel bearings for low floor tramcars.
Benefits
1.Effective prevention of electrical corrosion damage
2.Superior insulation properties, with performance improved greater than 10 times
3.Improved durability, with new optimized coating demonstrating 3 times the shock resistance of conventional ceramic coated bearings
4.Excellent heat dissipation
5.Dimensionally interchangeable with standard bearings.
