7922/DB/DF/DT 滾動(dòng)軸承的特點(diǎn)滾動(dòng)軸承與滑動(dòng)軸承相比,具有下列優(yōu)點(diǎn):1．滾動(dòng)軸承的摩擦系數(shù)比滑動(dòng)軸承小,傳動(dòng)效率高。一般滑動(dòng)軸承的摩擦系數(shù)為0.08-0.12,而滾動(dòng)軸承的摩擦系數(shù)僅為0.001-0.005;2．滾動(dòng)軸承已實(shí)現(xiàn)標(biāo)準(zhǔn)化、系列化、通用化,適于大批量生產(chǎn)和供應(yīng)，使用和維修十分方便；3．滾動(dòng)軸承用軸承鋼制造,并經(jīng)過(guò)熱處理,因此,滾動(dòng)軸承不僅具有
