详细介绍:
目前大部分绝缘轴承是在钢质套圈、保持架(或铜保)上涂覆陶瓷或树脂材料,滚动体采用陶瓷材料,涂覆陶瓷的绝缘轴承在绝缘、抗蠕变、散热性能上占有优势。全陶瓷绝缘轴承因其价格昂贵,应用较少。
这需要根据电机的电源状态来定。正常电网供电无高频电压电流成分,一般不使用绝缘轴承,只有高压电机大电机如400以上规格才使用。甚至于还可以不用。但现在变频电源供电,由于电源品质含有很多的高频成分,造成电机轴电流增加,因而在400以上规格化均应考虑此问题,甚至于再小此的规格也根据使用状况也考虑安装了绝缘轴承,如电动汽车,电轨道机车等使用的主电机一般100KW左右,都必须使用绝缘轴承(或者采用其它绝缘结构来保证轴电流不流通)。

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)+
