KR/KRV系列螺栓滚轮滚针轴承
KR/KRV系列螺栓滚轮滚针轴承是要由一根螺栓轴和厚壁外圈及其它轴承元件组成的轴承单元
曲线滚轮(也叫螺栓轴承,凸轮轴承,曲线滚轮滚针轴承,滚轮轴承,滚轮滚针轴承, 螺栓滚轮滚针轴承)KR, KRV系列主要是要由一根螺栓轴和厚壁外圈及其它轴承元件组成的轴承单元。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。外圈有两个整体挡边,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。 螺栓轴上可以带上六角螺母以便快速,方便地将轴承安装到对应的机器部件上。曲线滚轮主要适用于轨道传输等机械设备上。
1.承受冲击负荷,减少变形和弯曲应力;
2.螺栓为轴,配合螺母方便安装;
3.结构多样,用途广泛。
