厂家销向心滚针和保持架组件滚针轴承K505825 K525712 K556020 K556027滚动轴承
龙威轴承要求当滚针直接在轴或外壳中运转时，为使滚针保持架组件达到全部负荷容，内外滚道面硬度必须为58-62HRC，粗糙度≤0.32μm，表面必须与滚动轴承滚道相同。
LWB standard- When the needles are running directly in the shaft or in outer case, to make the needle retainer assembly reach its fully load capacity, the hardness of the inner and outer tray surface must reach 58-62HRC and roughness must not greater the 0.32μm, the surface quality must be the same of rolling bearing tray.
装配及相关尺寸 Assembling and relative dimensions
图2、图3为滚针保持架组件装配的相关尺寸，轴承装配时轴向固定方式使用图4至6所示。当使用于高速状况时，保持架与轴向限位间应加一个经热处理的垫圈，以避免保持架与限位直接接触。
Figure 2, Figure3 show the relative dimensions of the needle retainer assembly. The axial fixed way used in bearing assembling is show in Fig 4 and 6. When used for high speed, a heat treated washer should be added between the retainer and the axial limit so that direct contact of retainer limit can be avoided.
