Pilot bearing for track abuse
Anyone had any luck with a ceramic pilot bearing being claimed as a long lasting for high speed and high temps.

What brand is recommended. There are multiple choices - rubber gasket sealed or metal cover sealed. All fall under 6202 style. What's been a go to pilot and throw out bearing?
6202zz is double shield (metal)
6202rs is the plastic sealed.
9.95 for Nachi 6202-2N (rs)
koyo 6202RS 11.45
NSK 6202zz $6.80
NTN 6202ZZ $14.61

The Properties of Silicon Nitride (Si3N4)
Very low density (3.21 g/cm3)
Very high fracture toughness (7 MPam1/2)
Good flexural strength (850 MPa)
Very good thermal shock resistance: High thermal stress parameters (569 K)
Maximum operating temperature in an oxidizing atmosphere: 1,300°C
Maximum operating temperature in a neutral atmosphere: 1,600°C

The cage is made of PEEK. If you melt that, it'll be the least of your concerns at that point.
OP you are trying to solve a problem that doesn't exist? Most of us just install a quality bearing from timken, SKF, koyo, etc. which usually comes in the clutch kit, and dont think twice about it. Pilot bearing failure isn't common on our cars.
I wouldn't use a metal shield, as those are just a shield, not a seal.
