These wheels are big, strong and extremely well made. Brakes hold securely in place. Worked great for a mobile work cart. Harbor freight cart.

They roll smooth, lock down tight and don't budge. They swivel and roll with absolute ease. I have to unlock them by hand, which isn't a big deal, but it would be nice to be able to do it with my foot.

The bolts, lock washers and nuts are sturdy. Definitely heavy duty and came with screws and screwdriver. They are so strong and sturdy.

Whatever bearing they used for the plate feels crunchy. Didn't hold up.

The wheels turn so easily that the workbench will start rolling on its own on my relatively flat garage floor. The table rolls smoothly and the tires are big and soft. It weighs about 500 lbs and theses work great for moving it around.

Caster locks work perfectly, easy to engage and disengage with my foot. Wheels lock individually and i only need to lock 2 to stabilize the table. The one thing i will say is they lock easy but to unlock is harder.

Worked perfectly in my new welding table. The work bench is 4x8 with drawers, power tools, vise. Using on a wood shop cart with a planer on top.

I believe they would pretty quickly deteriorate.
