The inner part of the slide rail that is invisible to the naked eye is its bearing structure, which is directly related to its load-bearing capacity. At present, there are steel ball slides, roller slides and silicon wheel slides on the market. The former automatically removes the dust and dirt on the slide rail through the rolling of the steel ball, so as to ensure the cleanliness of the slide rail, and the sliding function will not be affected by the dirt entering the interior.
At the same time, the steel ball can spread the force around, ensuring the horizontal and vertical stability of the drawer. The debris produced during long-term use and friction of the silicon wheel slide rail is in the shape of snow flakes, and it can be brought up by rolling, and it will not affect the smooth sliding of the drawer.
