圓柱滾子軸承

圓柱滾子與滾道為線接觸軸承。負(fù)荷能力大，主要承受徑向負(fù)荷。滾動體與套圈擋邊摩擦小，適于高速旋轉(zhuǎn)。根據(jù)套圈有無擋邊，可以分有NU、NJ、NUP、N、NF等單列圓柱滾子軸承，及NNU、NN等雙列圓柱滾子軸承。該軸承是內(nèi)圈、外圈可分離的結(jié)構(gòu)。

內(nèi)圈或外圈無擋邊的圓柱滾子軸承，其內(nèi)圈和外圈可以向軸向作相對移動，所以可以作為自由端軸承使用。在內(nèi)圈和外圈的某一側(cè)有雙擋邊，另一側(cè)的套圈有單個擋邊的圓柱滾子軸承，可以承受一定程度的一個方向軸向負(fù)荷。一般使用鋼板沖壓保持架，或銅合金車制實體保持架。但也有一部
