Timken rear axle bearings and seals.

here is a past post

that post has a link to a good PCNC article with the ball bearing numbers

I also would like the bearing numbers for the tappered rollers as shown in this article

Thanks. I saw those articles but I can't get the 5208 2RSC3 part number to cross reference with Timken. I'm going to talk to a few race car builders and engineers next weeks and hopefully they can get some hard numbers. I'll let you know what I find out.

The nomenclature used is;

5200 = Double row medium duty metric and the 5208 denotes a 40mm bore (multiply the last 2 digits by 5). The 2RS denotes seals both sides.

For Timken this is a 5208W bearing, however in doing a bit of research Timkens catalog states that their double row bearings are NOT pre-lubricated and as such they seem to offer only a single sided shield.

I have them, I wish I didn't

MX144,
when you are asking about "Timken",

are you asking about the specific brand name of the rear axle ball bearing replacement

OR
are are you asking about converting to taper roller bearings

I was thinking of converting to the tapered roller bearings

I'm looking for a Timken brand inner double roller part number and a Timken part number for the outer bearing that doesn't require machining the axle hub to make it fit. I know from experience that Timken have the best manufacture quality and reliability. It doesn't make sense to be to put in parts of unknown origin in a car that I've spent lots of money and time on, especially such a crucial and relatively inexpensive part.
