For parts polishing

From Japan

On 2016-07-13 22:55:27

Besides buying bearings, I decided that something lightweight is better to use for polishing parts, and I am going well so far. Hardness is also sufficient. I do not know the durability if I try to use it a bit more.

Folding knife bush

From Japan

On 2014-06-24 13:23:09

It is different from usual way of using the bearings, but I used it for a folding knife bush (liner lock). It was a bad environment where friction was concentrated on one point and abrasion and rust easily occurred in steel balls. I am not worried anymore.
