More and more steel ball slides are used on furniture, and when the steel ball slides are in use, they may encounter difficulties in pushing and pulling, so how should the drawer steel ball slides be maintained?

1. The steel balls of the slide rail are inferior steel balls, there are pits and bumps, not full and round enough, or there is a problem with the material design of the slide rail itself

2. Too many items are stacked too heavy, which squeezes the drawer space, resulting in too high load on the slide rail and cannot run smoothly.

3. The use time is too long. Usually, the service life of the slide rail is 50,000 times of opening and closing. The service life is too long, and the steel balls inside are more or less worn, which makes it impossible to push and pull smoothly.

4. The slide rail is rusted, and the inner bead groove and steel ball are easily corroded and rusted in a high humidity environment.

5. The mounting rails are not aligned horizontally, the installation gap between the rails is too small or the screws are too long to block the drawer.
