What type of roller or ball bearing system do quality flat file cabinets use?

Quality commercial flat file cabinets use full-extension roller or ball-bearing drawer suspension systems that allow the drawer to open completely — providing full access to the entire drawer interior without having to reach in past partially extended hardware. Ball-bearing suspension is smoother and more durable than roller-only systems, especially under the substantial weight of fully loaded flat file drawers. Check that the suspension system is rated for the total weight of the drawer plus maximum load. Some economy flat file cabinets use simpler bottom-roller systems that work adequately for light use but wear faster under heavy professional use.
