随着工业自动化的发展,主机的结构向更小型、轻型、高精度、高速化发展,对于直线运动的导向、摩擦力提出了更新、更高的要求,要求有一种驱动力要小,承载力大,变形小的导向机构,所以一种新型的滑动导轨——直线滚动导轨开始在一些先进的 With the development of industrial automation, the structure of the host machine has been developed to be smaller, lighter, more precise and more rapid. Newer and higher requirements have been put forward on the guidance and frictional force of linear motion, and one requirement is that the driving force should be small and the bearing capacity Large, small deformation of the steering mechanism, so a new type of sliding guide - linear rolling guide began in some advanced
