  曲线滚轮(又名螺栓轴承) KR系列,KRV系列,NUKR系列等螺栓型滚轮滚针轴承是由G20CrMo螺栓轴经过HVI≥664,有效硬化层1.3mm精制而成,再由作为滚子组内滚道的螺栓及一个厚壁外圈组合。螺栓轴的台肩及压在螺栓上的端面挡圈组成了外圈沿两个侧面方向的引导面。当曲线滚轮在平滚道或凸轮盘上运动时,由于外圈的弹性变形,滚轮的内应力加大。因此应用于此种工作情况下的额定负荷请选择曲线滚轮一栏:(以下为详细说明)除此之外我司还可定制大外径CF,CRY,CYR,NCF等系列滚轮轴承。 KR  | 由挡边及挡圈轴向引导的曲线滚轮  |  KR...PP  | 带密封圈的曲线滚轮  |  KRE  | 带偏心套的曲线滚轮  |  KRE...PP  | 带偏心套及密封的曲线滚轮  |  KRV  | 由挡边及挡圈轴向引导的曲线滚轮,满针型  |  KRV...PP  | 带密封圈的曲线滚轮  |  KRVE  | 带偏心套的曲线滚轮  |  KRVE...PP  | 带偏心套及密封的曲线滚轮  |  NUKR  | 滚动体轴向引导的曲线滚轮,满滚子型  |  NUKRE  | 带偏心套的曲线滚轮  |  CR  | 英制系列曲线滚轮  |
