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.

What I'm saying is that the 6202 2Z/C3 is lubed with regular bearing grease, not graphite, and is not considered a high heat environment bearing. I have 4 of the 6202 2Z/C3 shielded bearings already. I was trying to locate the 'high heat, graphite filled bearing" that you mentioned, but the part number given isn't a "high heat graphite filled" unit. The ones in that same size that are graphite filled, high heat, are only rated for low speeds, not high speeds.

6202 2Z/C3 do not say anything about grease in it other than its probably normal stuff. 2Z is metal side covers and C3 is tolerance group. Special grease version needs more letters/numbers in type name. There are many variants available from different manufacturers. SKF high temp grease version is 6202 2Z/C3 GJN. Other possible option is SKF 6202 2RSH/C3 GJN which has rubber seals.
