圆柱滚子轴承(GB/T 283—2007)

                                                                                N型                                  NH型（NJ+HJ）                                          NF型

符号含义与应用

N—外圈无挡边　　　　　　NF—外圈有单挡边　　　　　　NH—内圈有单挡边(NJ)并带斜挡圈(HJ)

应用基本同前。N型不能承受轴向载荷，不能限制轴或外壳的轴向位移，常用作游动支承。NF型在有挡边一侧能承受较小轴向载荷，并能限制单向轴向位移，常成对使用。NH型能承受较小的双向轴向载荷，并能限制双向轴向位移。
