The load-bearing capacity of the drawer depends mainly on the quality of the rail steel. Drawers of different specifications have different thicknesses and load-bearing properties. When purchasing, you can pull out the drawer and press it hard with your hands to see if it will loosen, rattle or turn over. The material of the sliding rail pulley determines the comfort of the drawer when sliding. Slide rail plastic pulleys, steel balls, and wear-resistant nylon are the three most common pulley materials. Among them, wear -resistant nylon is the top grade, which is quiet and silent when sliding.
Depending on the quality of the pulley, you can push and pull the drawer with one finger. There should be no astringency and no noise. Choose the key points to see whether the pressure device works well, just try it out! See whether it is labor-saving and whether braking is convenient. But it should be noted that although the pressure device is very good, the price is more expensive.
