The importance of steel ball slides is second only to hinges. The best sliding function should be the natural combination of stability and load-bearing effect. Under rated load-bearing conditions, there is no obvious friction sound and jamming phenomenon, and the sliding is smooth. Both sides of the steel ball slide rail must be leveled. If there is a problem with the slide rail, in addition to the quality of the product, there is another reason for improper installation, which is likely to be caused by the lack of leveling on both sides. Like hinges, slide rails are frequently used hardware accessories and are very important in cabinet accessories.

It plays an important role in the use effect and life of the drawer. At present, the two most common types in the market are "iron plate sliding rails" and "damping sliding rails".

The general load-bearing capacity of the iron plate sliding rail is about 35 kg, and the damping sliding rail is between 45 kg and 70 kg. Not only is the pulling silent, but also the bearing capacity is greatly increased. Moreover, the damping slide rail can reduce the noise caused by severe mechanical collision and prevent premature aging of metal parts, and at the same time, it has the function of automatically removing dust. If the wall panel of the slide rail is thin and the workmanship is rough, there will be problems such as poor sliding, noise and damage after a period of use.
