LWB-滚针直径公差Table 1 needle diameter tolerance 单位 unit：um

LWB-配合 Combination

LWB精密滚针保持架的径向间隙，取决于内外滚道及滚针的加工精度。表2为依据不同的使用条件推荐的配合。

LWB :The radical gap of needle retainer assembly depends on the machined precision of the inner and outer trays and the needles. The table 2 shows the combination recommend as per the different operational conditions.

LWB-根据G6加工外壳时推荐轴公差

Table2 the recommended shaft tolerance of the casing when machined as per G6

龙威LWB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.
