本公司生產(chǎn)的高精密軸承主要指7000CTA、7000ACTA系列及760000系列,主要指P4、P5級精度等級,其中7000CTA、7000ACTA系列軸承主要應用在電主軸上,其旋轉(zhuǎn)精度及尺寸精度較高,適于高速運行;760000系列軸承主要應用于精密和高速的機床及精密的測量裝置中。
精密軸承的內(nèi)外套圈采用精煉軸承鋼GCr15,可以根據(jù)用戶要求采用其它軸承材料。
精密軸承的滾動體采用精煉軸承鋼GCr15軸承鋼球、陶瓷球,陶瓷球的材料主要為Si3N4、Zr〇2、AI2O3,陶瓷球具有低密度、耐磨、自潤滑性好等特點,特別適合高速、高精度、長壽命軸承使用。
精密軸承的保持架主要為酚醛層壓布管及增強尼龍保持架。
精密軸承的使用為多個組配使用,具體配合型式參照本公司樣本-組配角接觸球軸承。
精密軸承中760000系列代號的表示:
