Linear bearings are a linear motion system used in conjunction with cylindrical shafts for linear travel. Due to the contact between the load-bearing ball and the outer sleeve of the bearing, the steel ball rolls with minimal frictional resistance. Therefore, linear bearings have low friction, are relatively stable, do not change with the bearing speed, and can achieve stable linear motion with high sensitivity and accuracy. The consumption of linear bearings also has its limitations, mainly due to their poor impact load capacity and load-bearing capacity. Secondly, linear bearings exhibit significant vibration and noise during high-speed motion. The selection of linear bearing automation is included. Linear bearings are widely used as sliding components in industrial machinery such as precision machine tools, textile machinery, food packaging machinery, printing machinery, etc.
