電絕緣軸承采用特種噴涂工藝，在軸承的外表面噴鍍優(yōu)質覆膜，覆膜與基體結合力強，絕緣性能好，可避免感應電流對軸承的電蝕作用，防止電流對潤滑脂和滾動體、滾道造成的損壞，提高軸承的使用壽命。
該工藝不斷被改進，絕緣軸承中，在外圈或內圈表面有一層100μm厚的涂層，可承受最高1000 V DC的電壓。 特殊的噴涂工藝可形成一層厚度均勻、粘附力極強均勻的涂層，再經過進一步處理，使其能不受濕氣和濕度的影響。
分類
電絕緣深溝球軸承
電絕緣角接觸球軸承
電絕緣圓柱滾子軸承
帶有氧化物鍍層的內圈或外圈絕緣軸承
帶有電絕緣陶瓷滾動體的混合軸承
優(yōu)點
電絕緣軸承可避免電腐蝕所造成的損害，因此與普通的軸承相比應用在電機中可保障運行更可靠。而比起其它絕緣方法，如軸或外殼絕緣等，更加符合成本效益和可靠。絕緣軸承的外形尺寸和基本技術特點與非絕緣軸承相同，因此可以百分之百互換。
用途
適用于電機、發(fā)電機，特別是變頻電機應用更廣泛。
