I bought these to replace plastic casters as my new floors are hardwood and not old carpet. The holes almost match up so only minimal drilling is required. You will need your own fasteners as these are not included. They carry 30lb Formica cubes that are used as coffee tables. Not much movement is expected, but they spin easily and quietly on ball bearings and the wheels spin on rivets. Eventually I may cover the moving parts with silicone, but not now.
