Query: Bearings? More like gravel!

I bought these casters to use on a lunmber cart in my garage/workshop. I bought them because I thought that the high profile wheel would deal with grit on the floor pretty well. I can't believe how bad they are. The "bearings" are so worthless that the casters physically grind as you spin them- even without any weight on them. Rortaion of the wheel is OK, but spinning the caster on it's axis is terrible. This is a case of you get what you pay for. I'll be buying replacements somewhere else.
