Linear motion bearings is a bearing designed to provide a one-dimensional freedom of movement. Linear motion bearing structure is fitted with a cage in the outer ring. Cage equipped with many balls, sport can be an infinite loop. Further, both ends of the sleeve holder fixing spring. There is a side window on a straight track. This allows the ball portion and a shaft load rolling contact. These products can be relatively moved at a very low coefficient of friction. Therefore, linear motion bearings for many mechanical equipment, automation equipment and energy-saving equipment.
There are a variety of linear motion bearings. In general, it can be divided into rolling and plain bearing.

The former has a smooth movement, low friction, high rigidity, long life characteristics. Maintenance and replacement of these products are very easy. The latter design is very similar to the rolling bearing. They may be run on the raceway hardened steel or stainless steel.

Like many other bearings, linear motion bearings have a fairly wide range of applications. Currently, they are more widely used in electronics, machinery, equipment, robotics, tools, food machinery, packaging machinery, medical machinery, printing machinery, textile machinery, machine tools, automobiles and many other machinery industries.
There is no doubt that the use of linear ball bearings have many advantages. First, the mobile channel can be the starting friction and dynamic friction becomes very small. Therefore, it can help save energy and easier access to higher speeds. Secondly, as the load increases almost unchanged. In addition, it changes its coefficient of friction insensitive. Therefore, under heavy loads very small coefficient of friction. In addition, it can maintain long-term accuracy, which can extend the life of the machine. Third, linear motion bearings has a good interchangeability. Easy to install. In addition, it makes the mechanical structure is compact and lightweight. Fourth, you can simplify lubrication and maintenance.
