The structure of the linear motion ball bearing is that a cage is installed inside the outer ring, and the cage is equipped with a plurality of steel balls, which perform infinite circular motion. The two ends of the retainer are fixed by internal spring retaining rings, and there is a gap window on the side of the linear track where each steel ball works under force. This part is to make rolling contact between the loaded steel ball and the shaft. Relatively move with a very low coefficient of friction, so linear motion ball bearings are the most suitable bearings for mechanical equipment, automation equipment, and energy-saving equipment. Linear motion bearings are currently being more and more widely used in general or special machinery industries such as electronics, machinery, instruments, robots, tool machinery, food machinery, packaging machinery, medical machinery, printing machinery, textile machinery, CNC machine tools, automobiles, etc. middle.

Advantages of using linear motion ball bearings:

  1. Since the flow contact can minimize the starting friction resistance and dynamic friction resistance, it can save energy and easily obtain a higher movement speed.

  2. As the load increases, the friction coefficient has no sensitive change. Therefore, under heavy load, the friction coefficient is extremely small, and the accuracy remains unchanged for a long time, which can maintain the mechanical service life for a long time.

3. Linear motion bearings have good interchangeability, convenient installation and time-saving, and make the mechanical structure novel, small and light.

4. It saves oiling procedures and achieves the purpose of simplifying lubrication and maintenance.

5. Bearings with additional oil seals on both sides are also suitable for places with a lot of dust or where foreign matter is easy to invade.
