Double-row cylindrical roller bearing

机床用双列短圆柱滚子轴承

圆柱滚子轴承主要分为N10系列和NN30系列两种结构系列。N10系列单列圆柱滚子轴承通常作为要求承载能力大的机床主轴游动端的支承轴承

NN30系列双列圆柱滚子轴承是机床主轴最常用的轴承,该类轴承能承受较大的径向负荷,由于内、外圈可分离而不能承受轴向载荷允许轴承游动,因而在机床上常与双向推力角接触轴承、角接触球轴承、圆锥滚子轴承、推力球轴承组合使用,构成机床主轴的支承。圆柱滚子轴承主要分为N10系列和NN30系列两种结构系列。N10系列单列圆柱滚子轴承通常作为要求承载能力大的机床主轴游动端的支承轴承
