Title
(JA) 絶縁転がり軸受
Abstract
(JA) 【課題】電食を防止するとともに、軸などへの抱き着きや、内輪などからの脱落を防止できる絶縁転がり軸受を提供する。
【解決手段】絶縁転がり軸受は、鋼材からなる内輪2および外輪と、この内・外輪間に介在する複数の転動体と、内輪2の内周面2aに嵌合された略円筒状の絶縁ブッシュ10とを備え、絶縁ブッシュ10は、外径側に樹脂組成物からなる絶縁部8と、内径側に金属部9とを有し、絶縁部8と金属部9が別体で構成されており、金属部9は、周方向の一部に合い口9aが形成された割ブッシュであり、絶縁部8は、割ブッシュの合い口9aを外径側から覆う円筒部材である。
