标准摘要
[中文适用范围]： 本部分规定了系列4和5线性运动滚动轴承（带轮廓导轨）的边界尺寸和公差。这些轴承由带滑动件的轮廓导轨组成，能够承受各个垂直方向的力量和所有轴线上的力矩，并包含循环滚珠。这些轮廓导轨的内部设计由制造商自行决定。根据制造商的规定，可以将一个或多个滑动件安装在一条直线上。因此，这些元件的互换或组合只能在制造商允许的范围内进行。 [外文原描述]： ISO 12090-2:2011 establishes the boundary dimensions and tolerances for series 4 and 5 of linear motion rolling bearings, profiled rail guides. These bearings consist of profiled rails with carriages, which can support forces from all perpendicular directions and moments around all axes and consist of recirculating rolling elements. The internal design of these profiled rail guides is at the discretion of the manufacturer. An assembly can comprise one or more carriages on a linear profiled rail.
