Nine Star insulated bearings

 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)

Previous: Timken maintaining search for acquisitions
Next: ZYS’s 500,000-set clutch bearing project will be completed by the end of 2015
