(EN) Electrolytic corrosion preventive antifriction bearing
(ZH) 电蚀防止滚动轴承
要約
(EN)
The insulating layer 6 is provided on an inner ring 2 or an outer ring 3 in a range from the peripheral face fitted to a housing or a shaft over the end face. A bearing ring having the insulating layer 6 out of the inner ring 2 or the outer ring 3 is provided with a reference face 7 on the end face for the end face machining or the end face film thickness management. It is acceptable that the reference face 7 is the inner face of a step portion 8 formed on the end face or the material exposed face of the non-sprayed insulating layer 6 on the end face.

本发明的课题在于提供一种电蚀防止滚动轴承,其容易并且正确地进行电绝缘层的形成后的精加工和膜厚控制。在内圈(2)或外圈(3)上,从与外壳或轴嵌合的周面到宽度面,设置有电绝缘层(6)。在内圈(2)或外圈(3)中的,具有电绝缘层(6)的滚道圈上,在宽度面上设置宽度面加工用或宽度面膜厚控制用的宽度面基准面(7)。该宽度面基准面(7)既可为形成于宽度面上的台阶部(8)的内面,也可为宽度面中的未进行电绝缘层(6)的喷镀处理的材料露出面。
