I'm replacing my old pilot bearing it was lubricated with grease (when it was new it did self destruct after the lubricant got old).
I now am going to replace it with a dri-lube bearing (graphite lubed) it's rated up to 600F as long as the seals won't get damaged the lube will never get out or go bad due to age or loose it's lube film due to high temperature.

Does anybody else remember when sintered oillite bronze pilot bushings were common? They seemed to last a long time, at least the twenty or maybe thirty thousand miles beteen clutch changes on my 356 and early 911.

Sweet.
How does the construction compare to the stock bearing otherwise?
I should add that these are the pilot bearings on 944s as well and are also used (1x) for the mechanical radiator fan on early cars. I've got five spinning on a good day.

If my memory is right, Honda used them in the last gen. CRX.

Isn't the same bearing used in the release bearing assembly?

As you can see this one developed a blue hot spot on the inner race perhaps after it ran out of lube and some roller ***** got spit out (I never saw them when I took the clutch pack apart)

This failure is very rare.
I'd think that one either one of the seals failed and the grease flew out, or it was a very low quality bearing to start with.

Herman, I was trying to locate a graphite filled SKF bearing (versus the standard grease) and in my research the SKF 6202 2Z/C3 is a standard grease filled. The high temperature unit they list in the correct size has a sub 1000 RPM max speed rating. Not sure if this info from SKF's site will come through correctly or not, but here goes:
Deep groove ball bearings for high temperature applications
Principal dimensions Basic load ratings Limiting
speed
Limiting temperature Running in
required
Mass Designations
15 35 11 8,06 3,75 180 250 480 • 0,048 6202-2Z/VA201
35 11 8,06 3,75 360 350 660 – 0,048 6202-2Z/VA228
Max Speeds in bold.
I'm not sure if they have a 6202 high temp in the high speed rating. BTW, I'm not criticizing, just trying to research them because I wanted the graphite lubed unit after reading this thread.

I researched this as well....and ended up getting 10 Chinese units off eBay for $14 delivered. They look good and turn smoothly. I needed it for the radiator fan so easy access if it goes south.
