I needed new 2 inch rollers for a project. The standard units have a weight capacity of 65 pounds, which isn't enough to support my closet. I found these. Wider wheels and bearings in the wheel. They roll well, much better than the cheap bearingless wheels I use on other projects. Must withstand a nominal 100 lbs. My bikes came individually wrapped in plastic bags. No signs of paint chipping. I love how they roll. so many that I ordered another bag of rolls. I suspect I'll be replacing some of the cheap casters on older projects before I'm done.
