Whether the drawer can be pushed and pulled freely and smoothly, and how it bears weight, all depends on the support of the drawer slide rail. From the current technology, the bottom slide rail is better than the side slide rail, and the overall connection with the drawer is better than the three-point connection. The materials, principles, structures, and processes of drawer slide rails vary greatly. High-quality slide rails have low resistance, long life, and smooth drawers.
1. Classification of drawer slide rail specifications
① Roller type: This type of slide rail has appeared for a long time and is the first generation of silent drawer slide rails. Since 2005, it has been slowly replaced by steel ball slide rails on the new generation of furniture. The roller slide rail has a relatively simple structure, consisting of a pulley and two tracks. It can cope with daily push and pull needs, but the load-bearing capacity is poor, and it does not have buffering and rebound functions. It is often used on computer keyboard drawers and light drawers.
② Steel ball type: Steel ball slide rails are basically two-section and three-section metal slide rails. The most common structure is installed on the side of the drawer. It is relatively simple to install and saves space. Good quality ball bearing slides can ensure smooth push and pull, and have a large load-bearing capacity. This type of slide can have a buffer closing or a press rebound opening function. In modern furniture, ball bearing slides are gradually replacing roller slides and becoming the main force of modern furniture slides.
③ Gear type: This type of slide has hidden slides, horse drawer slides and other slide types, which belong to mid-to-high-end slides. The use of gear structure makes the slide very smooth and synchronized. This type of slide also has a buffer closing or a press rebound opening function. It is mostly used in mid-to-high-end furniture. Because of its high price and rare in modern furniture, it is not as popular as ball bearing slides. This type of slide is the trend of the future.
2. Introduction of damping slide rails
This type of slide rail is different from the above three types of slide rails. It uses the buffering performance of liquid to achieve an ideal silencing effect. It slows down the speed of drawer closing, especially slowing down the speed at the last distance, reducing the impact force, so the drawer will be closed more gently, reducing the wear of furniture wood, and achieving the best silencing effect. Its principle is mainly that the movable rod drives the piston to move, and the liquid flows from one side to the other through the hole, thereby achieving the effects of damping, silencing, and buffering. Moreover, the production process of the slide rail is very good, so the quality is also very high. In addition, the effect of the damping pulley ensures that it can be used for a long time without maintenance, and it is favored by many manufacturers.
3. Drawer slide rail size
Drawer slide rails are fixed on a certain track for the movement of other active parts of the drawer, with grooves or curves. The sizes of drawer slide rails are generally available on the market: 10 inches, 12 inches, 14 inches, 16 inches, 18 inches, 20 inches, 22 inches, and 24 inches. You can install different sizes of slides according to the size of your drawer models.
According to the length of the drawer slide, it can be divided into 27cm, 36cm, 45cm and other lengths. According to the material of the drawer slide, the commonly used drawer slides are roller slides, steel ball slides and wear-resistant nylon slides.
