[0017] Compared with the prior art, the drawer slide rail assembly has the following advantages:

[0018] 1. The drawer slide rail assembly has a linear guide column and a sliding ring, which effectively solves the problems of large operation noise and obvious vibration noise of the traditional rolling slide rail. The linear guide column provides a stable sliding track, and the sliding ring realizes low noise and high stability by using its excellent damping performance.

[0019] 2、The lower surface of the mounting plate and the outer surface of the guide column have a clearance, so that the mounting plate can be ensured to move along the guide column without being stuck due to manufacturing tolerances, thermal expansion and contraction, or slight deformation, etc. The clearance allows the mounting plate to slide smoothly along the guide column, and the appropriate clearance reduces the contact area between the mounting plate and the guide column, thereby reducing the friction, making the equipment run more smoothly, and possibly reducing wear and tear, prolonging the service life. During assembly, there may be some positional deviation. The clearance provides a certain amount of space to compensate for these errors, ensuring that the installation can be completed smoothly even in non-ideal conditions. If the mounting plate is loaded with a heavy component, the appropriate clearance also acts as a buffer, to some extent absorbing shocks and impacts, protecting the guide column from damage.

[0020] 3、The sliding ring and the mounting plate are made of plastic with self-lubricating properties, which has a low coefficient of friction and good wear resistance without the addition of external lubricants. The guide column is made of metal material, ensuring the stability and durability of the sliding rail system.
