九星电绝缘轴承？

 什么是电绝缘轴承？
电绝缘轴承就是指能够阻止电流通过，轴承自身具有绝缘性能的轴承总称，其绝缘性能通常是采用国际先进工艺在轴承外圈或内圈上加工一层氧化铝涂层，以承受电压直流。
电绝缘轴承分类，技术参数
一般分为内圈涂层绝缘轴承，外圈涂层绝缘轴承。其基本涂层能承受电压高达1000伏的直流。然而可根据客户要求供应500V—3000V直流的涂层。其代号采用国际轴承代号。
电绝缘轴承应用场合
主要应用在大功率电动机，风力发电机，铁路机车牵引电机，变频电机，发电机等场合。
电绝缘轴承型号分类
深沟球电绝缘轴承，圆柱滚子电绝缘轴承，调心球电绝缘轴承，角接触球电绝缘轴承，调心滚子电绝缘轴承，圆锥滚子电绝缘轴承。其型号表示方法和普通型号轴承一致，只多了一些后缀，参考国际轴承代号。SKF:VL0241 VL2071 VA3091 FAG:J20A

What is the electric insulation bearing?
It means bearing itself has the insulation performance to prevent current through. The insulation performance usually adopts international advanced technology to coat a oxide aluminum layer on rings to withstand voltage dc.

Electric insulation bearing classification Technical parameters
Generally, it is divided into the inner-ring coating insulation bearing, outer-ring coating insulation bearing. The basic coating can withstand voltage up to 1000 v dc. However, our bearings could run within 500 v-- 3000 v dc safely, according to the customers’ different requirements .The code adopts the international bearing code.

Electric insulation bearing applications
Mainly used in high power motor, wind generators, railway locomotive traction motor, frequency conversion motor, generator, etc.

Electric insulation bearing type classification
Electric insulation deep groove ball bearings, electric insulation cylindrical roller bearing , electric insulation self-aligning ball bearings, electric insulation angular contact ball bearing, electrical insulating self-aligning roller bearing, electric insulation taper roller bearing. The model representation is consistent to the general model bearing, only adding a few suffix. International bearing code is also available for reference.
