圆锥滚子轴承
该类轴承装有圆台形滚子,滚子由内圈大挡边引导
设计上使得内圈滚道面、外圈滚道面以及滚子滚动面的各圆锥面的顶点相交于轴承中心线上的一点
单列轴承可承受径向负荷与单向轴向负荷,双列轴承可承受径向负荷与双向轴向负荷
适用于承受重负荷与冲击负荷
按接触胸(α)的不同,分为小锥角、中锥角和大锥角三种型式,接触角越大轴向负荷能力也越大
外圈与内组件(内圈与滚子和保持架组件)可分离,便于装拆
后置辅助代号"J"或"JR"的轴承具有国际互换性
该类轴承还多使用英制系列产品
主要适用的保持架:钢板冲压保持架、合成树脂成形保持架、销式保持架
主要用途:汽车:前轮、后轮、变速器、差速器小齿轮轴。机床主轴、建筑机械、大型农业机械、铁路车辆齿轮减速装置、轧钢机辊颈及减速装置
