Rubber protects vinyl or laminate flooring from scratches. The wheel tire is softer, non-marring silicone appropriate for rolling on a hardwood floor. Shelf top roller on track design maintains maximum vertical and horizontal shelf stability.
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.
