They hardly move with a 200 pound table on them.
The cabinet is about 6 feet tall so wanted smaller wheels for it. Have purchased several sets and have had no issues with any of them. Having large fastening screws and washers were a plus.
They work great on smooth surfaces and not so much on gravel. They have smooth operation with good bearings and good mounting plates. Great rollers, easy to install, comes with everything you need.
