ISUTAMI linear bearing is a kind of linear motion system, which is used to coordinate linear stroke and cylindrical shaft. As the bearing ball and bearing jacket point contact, the steel ball with the minimum friction resistance rolling, so the linear bearing has small friction, and relatively stable, does not change with the speed of the bearing, can obtain a high sensitivity, high precision of smooth linear motion. The European system of linear bearing consumption also has its limitations, the most important is that the impact load capacity of linear bearing is poor, and the bearing capacity is poor, and then the linear bearing vibration and noise in high speed movement is large. Linear bearing is widely used in precision machine tools, textile machinery, food packaging machinery, printing machinery and other industrial machinery sliding parts.
