The rapid development of China's economy has provided a larger development space for ball screws and linear guides. Linear guides have become more and more common in the industry due to their unique characteristics. Linear guides are mainly used in automated machinery and equipment, and are widely used. In particular, square guides can also be used in the case of preload. So far, bearings with spherical ball elements have been used. The effect is quite significant. It is worth mentioning that if the envelope size is not increased, it needs a higher load capacity than the square ball guide. Therefore, the square and the circular need to be used together, and the effect is self-explanatory. Metaphorical
The function of the ball screw guide rail can also be used to support and guide the moving components to make a reciprocating linear motion in a given direction. This has an indirect relationship with the coefficient of friction. There is no need for an intermediate medium between the moving element and the fixed element of the linear guide rail, but a rolling steel ball is used. Because the rolling steel ball is suitable for high-speed motion, has a small friction coefficient and high sensitivity, it meets the working requirements of moving components and greatly promotes the rapid development of automated machinery.
Secondly, in order to improve the sensitivity of the system, reduce the movement resistance, and correspondingly reduce the preload, and in order to improve the retention of the movement accuracy, this undoubtedly has higher requirements for the automation performance of the linear guide. The automatic performance of linear guides spreads the force widely and expands the area of bearing force. In order to achieve this, the groove shape of the guide rail system has a variety of shapes. These are what we often call round and square. The combination of the two types has excellent development requirements for the performance of automated machinery.
