滚针轴承

滚针轴承是一种带有圆柱滚子的滚子轴承。与它的直径相比，辊子又细又长。这种辊称为滚针。尽管截面较小，但轴承仍具有较高的承载能力。滚针轴承配有细而长的滚子 (滚子直径D ≤ 5毫米，L/D ≥ 2.5，L为滚子长度)，因此径向结构紧凑。当其内径尺寸和承载能力与其他类型的轴承相同时，外径最小，特别适用于径向安装尺寸有限的支撑结构。
可以根据不同的应用选择不带内圈的轴承或滚针和保持架组件。此时，与轴承配合的轴颈表面和壳体孔表面直接用作轴承的内外滚动表面。为了保证与带套圈轴承具有相同的承载能力和运行性能，轴或外壳孔的滚道表面的硬度、加工精度和表面质量应与轴承套圈的滚道相似。这种轴承只能承受径向载荷。
