Linqing Nine Star Bearing Science & Technology Co., Ltd provides electrically Insulated 
bearings with oxide ceramic insulating layers on the bearing ring. Applied with plasma 
technology, the insulation has a guaranteed breakdown resistance of at least 1000V AC 
or DC. Two variants are available:
VL0241: Insulation on the outer ring
VL2071: Insulation on the inner ring


Electrically Insulated Bearings Advantages
1. Higher operational reliability through optimum protection against electrical corrosion
2. More economic than, for example, insulation on housings or shafts
3. Interchangeable: Same key dimensions and technical properties as conventional bearings
4. Coating resistant to damage if correctly handled


Electrically Insulated Bearings Typical Applications
A. Traction motors of railway vehicles
B. Electric motors (AC/DC)
C. Generators (e.g. in wind turbine generators)+
