电绝缘轴承采用特种喷涂工艺,在轴承的外表面喷镀优质覆膜,覆膜与基体结合力强,绝缘性能好,可避免感应电流对轴承的电蚀作用,防止电流对润滑脂和滚动体、滚道造成的损坏,提高轴承的使用寿命。
该工艺不断被改进,绝缘轴承中,在外圈或内圈表面有一层100μm厚的涂层,可承受最高1000 V DC的电压。 特殊的喷涂工艺可形成一层厚度均匀、粘附力极强均匀的涂层,再经过进一步处理,使其能不受湿气和湿度的影响。

电绝缘深沟球轴承
电绝缘角接触球轴承
电绝缘圆柱滚子轴承
带有氧化物镀层的内圈或外圈绝缘轴承
带有电绝缘陶瓷滚动体的混合轴承
优点
电绝缘轴承可避免电腐蚀所造成的损害,因此与普通的轴承相比应用在电机中可保障运行更可靠。而比起其它绝缘方法,如轴或外壳绝缘等,更加符合成本效益和可靠。绝缘轴承的外形尺寸和基本技术特点与非绝缘轴承相同,因此可以百分之百互换。
用途
适用于电机、发电机,特别是变频电机应用更广泛。
