    Loose Needle Rollers松针滚筒

    Needle Rollers for bearings is a roller with a cylindrical roller bearings, relative to its diameter, both the thin and long rollers.用于轴承的滚针是一种带有圆柱滚子轴承的滚子,相对于它的直径来说,薄滚子和长滚子都是如此。 this is called needle roller.despite its smaller cross-section, still has a higher load bearing capacity, therefore, especially suitable for the radial space-constrained occasions.needle pins contour surface in the proximal surface of the slight contraction.这就是所谓的滚针。尽管其横截面较小,仍然具有较高的承载能力,因此,特别适合于径向空间受限的场合。针脚轮廓面在近端表面轻微收缩。 needle and raceway contact line results can be amended to avoid damaging the edge of the stress.针和滚道接触线的结果可以修改以避免损坏边缘的压力。

    Super Precision Needle Rollers are designed specifically to handle large radial loads in high-speed spindle applications that demand high running accuracy (runout) of bearing-spindle arrangements.超精密针滚筒专门设计用于处理高速主轴应用中的大径向负载,这些应用要求轴承主轴布置具有较高的运行精度(径向跳动)。

    Needle rollers main use is as rolling elements in bearings where they are particularly useful when space is limited and a high radial load is required.滚针主要用作轴承中的滚动元件,当空间有限且需要高径向载荷时,它们特别有用。 They are also useful as locating pins and mini shafts.它们也可用作定位销和迷你轴。

    Some specialist bearings have convex barrel shapes or concave profiles depending on the application type and conditions.一些专业轴承根据应用类型和条件具有凸起的桶形或凹形轮廓。 pure cylindrical roller bearings cannot support any load in an axial direction.纯圆柱滚子轴承不能承受任何轴向负荷。 if axial support is required a separate bearing arrangement will be required.如果需要轴向支撑,则需要单独的轴承布置。
