Main functions of different components of linear guide

  The main function of linear guide is to support and guide, and its surface will also bear moving parts, which is what we often call load. The direction of the load is controllable, and the motion repeatability is very large, repeated movement, but in the whole movement process, the load will produce greater friction on the guide rail, but after the ball design, the friction between each other is greatly reduced. In addition, the linear guide rail is basically used with high-precision machinery.

1： Slider: the biggest feature of linear guide should be fast motion, mainly linear motion. The realization of this function is mainly attributed to the slider, which is one of the indispensable components on the linear guide. First of all, if there is no slider design, then its trajectory should be curved, which is very inconvenient for mechanical equipment, because mechanical equipment requires linear motion, and can ensure the main accuracy of motion.

2： Fixed element: its maximum function is directly provided by linear guide. The main material of fixing elements is also hard steel. When it is mounted on a flat surface, it needs repeated friction and friction. The accuracy requirement is relatively high. On the surface of the linear guide, there must be grooves, which are mainly used to provide the movement and sliding of components. Therefore, the cross-section structure and shape of linear guide are very complex; on the other hand, there is no strict regulation on the shape of groove, and the number is not completely uniform. The specific requirements of groove and shape are mainly determined according to the requirements of installation equipment.
