RV6 Bearing Numbers

Does anyone have the Timken bearing and race part numbers for the standard Cleveland main wheels?

The numbers for the slightly 'looser tolerance' versions are
08125 bearing
08231 race

You get to decide whether its worth paying roughly 5 times as much for the space grade version (numbers escape me....)

Thank you ! - There is nothing to decide. The fit is set by the pre-load not the manufacturing tolerance. The fit is very course considering you have to back off the nut until you align the cotter pin. A tighter tolerance won't do anything but add cost

To be clear, this isn't about preload. The 'loose' tolerances is a reference to how tight the machining is on the rollers and raceways. If someone posts the p/n's for the actual spec'd bearings, you can look up both & see the numbers.

Think machined to 4 digits past the decimal instead of 6 digits past the decimal; that sort of thing.

Not implying that the numbers I gave you are trashy bearings; they're not. But the original numbers are tighter tolerance.

I am not at the port but do have the part #s there. If you don't come up with what you need email me and I will get the info to you. If you look at the side of the bearing or the race the # will be stamped there and Napa or other part stores should have the none certified version of them. IIRC the aviation # has an A added on to it? Larry

Here's a writeup from a vendor hyping the advantages of 'aviation grade' vs 'automotive'.

The vendor's statement is pretty much what I've always heard about the difference (from vendors ).

According to the link above, you add the suffix -20629 to the numbers I gave you to get the 'aviation grade' bearings.
