Linear bearing its structure is equipped with a cage within the outer ring, the cage is equipped with a number of retainer, and for endless reincarnation. Both ends of the retainer are fixed with an inner spring retainer ring, and a notch window is provided on the linear track where the steel balls are forced to work. This area is the point where the loaded ball contacts the shaft. With copper alloy bearing very low coefficient of friction relative movement, so linear bearings are mechanical equipment, automation equipment, energy-saving reciprocating motion bearing equipment, such as the most suitable selection of bearings. Linear bearings are currently being used more and more widely in general or special machinery industries such as electronics, machinery, instruments, robots, tool machinery, food machinery, packaging machinery, medical machinery, printing machinery, textile machinery, .

Advantages of using linear bearings:

1. Additional oil seals on both sides of the bearings are also used with more dust or foreign body easily invaded place.

2. The load increases, but the friction coefficient is not sensitive to changes, so under heavy load, the friction coefficient is extremely small, and long-term self-lubricating flanged sleeve to maintain the same accuracy, long-term mechanical life can be maintained.

3. Linear motion bearings interchangeability, installation and use of convenience saving time and make the mechanical structure of novelty, small, light weight characteristics.

4. Save oil to the formalities, to simplify the purpose of lubrication and maintenance.

5. Because the contact can make the start of the friction and dynamic friction friction resistance is extremely small, so you can easily get a higher speed.
