Review on 🔒 Stainless Steel Locking Swivel Caster by Enjucom by Hesham Peltier

I bought the 2" set in October 2019. They were for a "fold out stand" that holds my planer on one side and my jet spindle on the other Grinder held - total weight about 140 pounds.. I have a small workshop and pretty much all my power tools are on moveable stands, but I usually like 4" or 5" casters because they roll over cracks and debris. I had to use these smaller casters for this stand so the height of the sanding table isn't too high (I'm only 5'7"). At first these videos were perfect. But this stand only pops out when I need the planer, so it stays in one place on the concrete floor for a long time. And that's the problem - they get very distinct flat spots that make rolling the stand very difficult, and then they hit, shake, shake as they hit the flats. I'm looking for a replacement that doesn't develop those heavy flat spots. Therefore only 3 stars.
