500mm Lock Heavy Duty Drawer Runner

Material and load-bearing capacity
Heavy-duty rails are made of high-strength cold-rolled steel (thickness 1.5-2.5mm), with galvanized or blue-galvanized surface treatment to improve rust resistance and wear resistance. Load-bearing capacity can be divided according to the model:

51mm wide rail: load-bearing 150 pounds (about 68kg), suitable for ordinary machinery or light furniture.
53mm wide rail: load-bearing 300 pounds (about 136kg), with locking and damping functions, suitable for RVs or medical equipment.
76mm wide rail: load-bearing 460 pounds (about 220kg), industrial-grade applications such as welding workshops or heavy-duty shelves.
Key parameters also include single-sided installation clearance (such as 19±0.3mm) to ensure stable operation under load.
