Description

Technical Field

[0002] Metal linear bearings are a kind of linear motion system produced at low cost. They are used in conjunction with cylindrical shafts for infinite strokes and are widely used in sliding parts of industrial machinery such as precision machine tools, textile machinery, food packaging machinery, and printing machinery. Linear bearings are a kind of linear motion system. They are used in conjunction with cylindrical shafts for linear strokes. Since the load-bearing ball and the bearing outer sleeve are in point contact, the steel ball rolls with the minimum friction resistance. Therefore, the linear bearing has low friction and is relatively stable. It does not change with the bearing speed. It can obtain stable linear motion with high sensitivity and high precision. The consumption of linear bearings also has its limitations. The most important thing is that the impact load capacity of the bearing is poor, and the load-bearing capacity is also poor. Secondly, the linear bearing has large vibration and noise when it moves at high speed. The automatic selection of linear bearings is included. Linear bearings are widely used in sliding parts of industrial machinery such as precision machine tools, textile machinery, food packaging machinery, and printing machinery. Linear bearings are used in conjunction with hardened linear transmission shafts. For a system with infinite linear motion, the load ball and the hardened transmission shaft are in point contact, and the allowable load is small, but during linear motion, the friction resistance is minimal, the precision is high, and the movement is fast.
