Sliding bearing is used in end supported applications, where spanning or bridging a gap is required.They have the greatest range of industrial application. However, care must be taken to select a shaft diameter to minimizes deflection. Precisely ground bearing track and plastic retainers provide smooth and quiet performance. Seals at both ends keep out contaminants and retain lubrication giving maximum travel life. The outer circumference of linear bearing is a cylindrical shape with highest accuracy, and to use is possible over a wide range of applications.

A linear-motion bearing is a kind of bearing that aims at offering free motion in one dimension.The structure of the liner motion bearing is that a retainer is built in the outer ring. And the retainer is equipped with many steel balls doing infinite circulatory movement. Besides, the two ends of the retainer are fixed with the spring collar. There is a side window in the straight track.This section is allowing the loaded balls and the axis to do the rolling contact. These products canmove relatively under a very low coefficient of friction. Therefore, the linear motion bearings are appropriate for many mechanical equipments, automation equipments, and energy-saving equipments,etc.

Like many other kinds of bearing products, linear motion bearings have a quite wide range of application.At present, they are more widely used in the electronics, machinery, equipment, robots, tools, food machinery, packaging machinery, medical machinery, printing machinery, textile machinery, machine tools, automobiles and many other mechanical industries.

There are various kinds of linear motion bearing. Generally, it can be divided into rolling-element bearings and plane bearings. The former has the characteristics of smooth motion, low friction,high rigidity and long life. It is quite easy to maintain and replace these products. The latter category is very similar in design with the rolling-element bearings. They can perform on hardened steel or stainless steel raceways.
