Ceramic crank bearings

[Testname111]

What do you guys think? Before I drop 100$ on bearings?
Long service life, but are high pressure bearings a thing? Like so I don't need oil seals

If only the zz bearings had option to have them welded on

Are you having problems with crank bearings going bad?

I'm not allowed to delete so I'll leave this here, Oops LOL

No but I would like to try them out as they are rust proof being not made of steel

 

[Larry Trotter]

Well if you have rust in your crankcase you have bigger problems than ceramic bearings will solve.

As long as you use a good quality bearing it will out last the top end, I bought a dozen that were made in Germany several years ago that are real smooth. I left the outside dust cover on both crank bearings to help keep crankcase pressure from blowing out a seal.

6202( c3 ) with the rubber seals skf because the rubber seals are better on the clutch side and remove the inner seals on the engine side c3 are loose fit to expand when hot and the metal seals don't really seal and can collect dirt 27x15 x5 and 27x15x7 Vinton seals double lip with the spring found @123 bearings
also put a skim coat of ultra grey around the seal... If you're crank is out of Tru and wobbly is why the seals on most engines fail or work there way out...
