Intelligent Logistics Warehousing Application

The automatic function of straight-line guides in China is to spread the working force widely and expand the bearing area.To achieve this, the groove shapes of the guide rail system are various.

Linear guides are now mainly used in automated machinery and are widely used, especially square guides, which can also be used for bearings with preload. To date, bearings with ball elements have been used.It is also obvious that if a higher load capacity is required than a square ball guide without increasing the envelope size, the effect is self-evident when square and round are used together.

In addition, in order to improve the sensitivity of the system and reduce the motion resistance, the preload should be reduced accordingly. In order to improve the accuracy and accuracy of motion, the automatic function of the straight-line guide rail has higher requirements.

The ball screw guide can also be used to support and guide moving parts in reciprocating straight lines in a given direction.This is directly related to the size of friction. The moving and fixing elements of the linear guide rail use rolling balls instead of intermediate media.Because rolling steel balls are suitable for high-speed movement, have small friction coefficient and high sensitivity, and meet the working requirements of moving parts, which also greatly promotes the rapid development of automatic machinery.
