To determine whether the load-bearing capacity of furniture slides is up to standard, you can quickly verify it by using the following simple methods, combined with product information and practical testing:

Look at the product identification: the regular slide rail will be marked with the rated load (such as "load bearing 50kg"), and the actual weight of the furniture (such as the total weight of the internal items in the drawer) should be matched when choosing, and the margin of more than 20% should be reserved.
Test load-bearing stability:
When there is no load, the push and pull are smooth and there is no jamming, and there is no obvious abnormal noise or shaking;
Load items close to the rated weight (such as putting heavy objects of corresponding weight in a drawer), push and pull 10-20 times repeatedly to observe whether there is deformation, jamming, and whether the connection between the track and the furniture is loose.
Check the material and structure:
Most of the high-quality slide rails are thickened cold-rolled steel (thickness of more than 1.2mm), the surface is treated with anti-rust treatment (galvanized and chrome-plated), and the load-bearing parts (such as balls and track walls) are free of deformation and burrs;
The ball slide is more load-bearing than the roller slide, and the fully pull-out slide rail needs to focus on checking the firmness of the rail connection.
Reference use cases:
Light load (such as wardrobe drawers, 20-30kg): ordinary slide rails are sufficient;
Medium and heavy loads (such as kitchen drawers, cabinets, 30-80kg): thickened and heavy-duty slides are required;
Over-heavy load (e.g. tool cabinet, more than 80kg): special industrial-grade slide rails are required, and there is a reinforced fixing design.

If there is bending of the track, pushing and pulling jamming, loose joints, or no clear load-bearing identification after loading, it can be basically judged that the load-bearing is not up to standard.
