Ceramic bearings. was created by Lambert
Hi. While looking at another project I happened upon silicon nitride bearing rolling elements. They allegedly have massive amounts of resistance to adverse operating conditions, especially wetting. Obviously the first thought was Jimny king pin bearings. Has anyone else found these and or a supplier and tried them?

I can imagine that ceramics would be a class above on static applications but I can't see ceramics working with something that takes shock loads in the way that a hub will.

Ceramics, fantastic wear but brittle, is my first thought,

Just a thought mind.... never used them and don't fully understand the applications for them.

My thoughts on shock loading were that if the bearings are acting in a pair and have the correct pre load they should not experience any acceleration between the component parts and so shouldn't be badly damaged. Plus the tyre is taking the majority of the shock anyway, it's not like a steel on steel impact? More research needed.
