Drawers slide on rails that carry their weight while keeping the front panel aligned.

The longer version

A drawer carries its load on two rails fixed to the cabinet, one on each side. Those rails take the weight and keep the box from tipping as it extends, while the front panel hides the gap and keeps the opening looking regular. Rollers or sliding strips cut friction so a loaded drawer still moves with one hand.

Better slides also add a stop so the drawer cannot be pulled out onto the floor, and some allow full extension so the back of the box is reachable. Cheap runners fail by binding, because the load concentrates at a single point; spreading contact along a longer track is what keeps the motion smooth under weight.
