螺栓型滚轮轴承_类型,系列,型号技术资料
螺栓型滚轮轴承有英制螺栓滚轮轴承和公制螺栓滚轮轴承，有如下几个系列：
- >> 公制螺栓型滚轮滚针轴承CF、KR系列
- >>公制螺栓型滚轮滚针轴承NUKR、PWKR等
- >> 英制螺栓型滚轮滚针轴承承CR、CF系列
螺栓型滚轮轴承也叫做螺栓型曲线滚轮一般为满装滚子结构，螺栓轴滚道部位经过淬火，为避免应力集中，滚轮的厚壁外圈外表面为弧形。螺栓型滚轮轴承外圈有两个整体挡边，螺栓型滚轮轴承轴向由滚子引导。螺栓轴头部和压装的侧挡圈通过滚子为外圈提供轴向支承。
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。
螺栓型滚轮轴承特点
◆是由一个机加工的螺栓，推力垫圈，一个外圈与一个滚针和保持架组成或满装滚动体组组成的完整单元
◆具有带凸度外表面的厚壁外圈
◆能承受高径向力
◆采用DIN 51825-KP2N-25规定的锂基复合皂脂润滑
◆可通过轴进行再润滑
◆可用下列密封防止污染和水侵入
- --唇密封
- --间隙密封货
- --迷宫密封
◆由于下列原因容易安装
- --螺栓端部有螺纹以及
- --螺栓带肋端有曹或六角孔
- 带偏心套的螺栓型滚轮
采用偏心调整外圈位置可与运转轨道相配。
这样
- --当采用一个以上的螺栓型滚轮时可改善载荷分布
- --准许预加载的线性系统。
从NUKR,NUKRF,PWKR...2RS系列开始，有一种新的优化的外圈表面轮廓形状。
带这种新轮廓形状的螺栓型滚轮具有：
◆较低的赫兹压力
◆如果出现倾斜边缘载荷较低
◆相配的轨道的磨损较小并
◆延长轨道的工作寿命。
用后缀“A”来表示具有这种新轮廓形状的滚轮。

说明：
1、表中所列基本额定载荷、极限转速和重量，仅供选择参考用。
2、轴承外圆为圆柱面时，在现轴承型号后缀后X，例如：NUKR35X .
3、油润滑时，极限转速为表列数值增加30%，带密封的情况除外。Note:
1. These load, speed and mass is reference of choice only.
2. For cylindrical outer race, add the suffix X, e.g. NUKR35X.
3. With an effective oil supply, the limiting speed can be increased by about 30%, except for sealed roller followers.

注： 1.表中所列基本额定载荷重量，仅供选择参考用。
2.轴承采用圆筒外轮或球面外轮，需在轴承型号后缀加R或X
例如：
3．其它特殊附件需订货时说明，如润滑油嘴，螺母，堵头。
4．以上曲线滚轮都为六角孔，如要采用一字型，需订货时特别说明！
5．以上曲线滚轮都为不带偏心，如需偏心型，如：KRE 16 或CFE 16 BUU，需订货时特别说明！
CZYF-曲线滚轮的螺栓作滚道的部位是经过淬火的。为避免应力集中，滚轮的厚壁外圈外表面为弧面形。曲线滚轮有带单、双密封圈、不带密封圈、带密封环的各种规格的型号。带密封圈存储润滑脂空间大、提供长久性润滑，并延长润滑间隔。密封圈材质为N220或聚四氟乙烯，其运转温度范围分别为 -30°C 至 + 100°C 或 -30°C 至 + 180°C 。密装式的曲线滚轮它可承受较重的载荷但转速较低，且必须经常再润滑
