Good slides allow a very wide drawer to work well.

How’s THIS for wide drawers?

Another example would be high quality tool cabinets (Snap-On, Mac, etc…) used by pro auto mechanics. They’re wide, carry LOTS of weight, and work wonderfully for years.

You could cheaply and easily shop-build a wide and heavy drawer, without expensive slides, by using a center guide, and rollerblade wheels on the drawer sides running on rails. The wheels carry the weight, the guide keeps it straight.
