Review on Groove Bearing Bearings MR83ZZ L 830ZZ by Dwayne Pore

I bought these to replace some fan bearings that had been running for too many years and now they work great. I later got a noisy CPU fan in an old Dell unit and these bearings were the right size to fix that fan as well. Intuition! I have 4 left so it may be a while before I need to buy more but I definitely will.
