Really fast wear
I bought these as same size replacements for my bike front hub. I fitted with bearing pale colour bearing grease and preloaded and locked. After 100k they had worn from 4.5mm to 3.9mm and the grease had changed to a dark grey with tiny silver specs. I can only conclude these bearings are not hard enough and have simply worn down.
