This type of slide has been around for a long time. It is the first generation of silent drawer slides. Since 2005, it has been slowly replaced by steel ball slides in the new generation of furniture. The roller slide has a relatively simple structure, consisting of one pulley and two rails, which can cope with the daily push and pull needs, but it has poor bearing capacity and does not have buffer and rebound functions. It is commonly used in computer keyboard drawers and light drawers.
The steel ball slide is basically a two-section or three-section metal slide. The more common one is the structure installed on the side of the drawer, which is relatively simple to install and saves space. The high-quality steel ball slide rail can ensure smooth sliding and large bearing capacity. This type of slide rail can have the function of buffer closing or pressing rebound opening. In modern furniture, steel ball slides are gradually replacing roller slides and become the main force of modern furniture slides.
