Review on PGN 6001 ZZ Shielded Ball Bearing Power Transmission Products by Trey Michaels

I love these bearings. I have a Walker bariatric rollator. I am 70 pounds under the weight limit but the bearings in the wheel forks keep failing and the entire rollator needs to be replaced. The last one I got broke the bearings the first time I sat on it. So I ordered these bearings and replaced them myself. It's been a few months since I installed these bearings and they're still intact and working great and cost less than a dollar each.
