低溫軸承的材料常使用不銹鋼軸承鋼9Cr18、9Cr18Mo制造;軸承套圈材料采用G95Cr18和G102 Cr Mo不銹鋼,或采用進(jìn)口高氮不銹鋼Cronidur30(X30 CrMoN15-2)及X.D15N.W(X40 CrMoVN16-2);滾動(dòng)體材料采用G95Cr18和G102 CrMo不銹鋼或氮化硅(Si3N4)或氧化鋯(ZrO2);保持架采用具有自潤(rùn)滑、耐磨損和耐低溫的非金屬材料陶瓷材料制成的混合陶瓷球軸承,這些材料應(yīng)滿足工作溫度在-253℃依舊可以正常工作,當(dāng)然,如果低于-253℃時(shí),可選用6Cr14Mo材料但必須在真空環(huán)境中使用。
