Default Re: My small end bearing failed

Japanese IKO KT101415
which are 10x14x15 mm $6.42 ea

These bearings are great. They're exactly the same size as my stock bearings, but it's easy to tell by looking these are superior, and the stock ones are toys.

The outer dimensions of the race is the same, but I can see several important differences. For one thing, the rollers are longer. Also the inside of the cages are a lot more robust looking, and offer more support to the rollers, but at the same time the IKO are about 1.5g lighter. They both have the same number of rollers. Looking closely at the IKO, they look Japanese precise, where the Chinese ones look, kinda close.
