What determines how smoothly a filing cabinet drawer opens and closes?

Drawer slide smoothness depends primarily on the quality of the drawer bearing system. Commercial cabinets use full-extension ball-bearing slides that support the full drawer weight and provide smooth, consistent operation throughout the product's life. Budget cabinets use friction slides that wear over time. Steel gauge, frame squareness, and drawer interlock mechanisms also affect smoothness.
