Metal linear bearings are linear motion systems that are produced at low cost for use with infinite strokes in conjunction with cylindrical shafts. Widely used in sliding parts of industrial machinery such as precision machine tools, textile machinery, food packaging machinery, printing machinery. Since the bearing ball is in contact with the bearing shell, the steel ball rolls with the minimum frictional resistance. Therefore, the linear bearing has small friction and is relatively stable, and does not change with the bearing speed, and can obtain a smooth linear motion with high sensitivity and high precision. Linear bearings also have their limitations. The most important thing is that the bearing impact load capacity is poor, and the bearing capacity is also poor. Secondly, the linear bearing has large vibration and noise during high-speed motion.
