Chicago Rawhide (CR) are owned by SKF, and the SKF seals website says:

In response to the demands of an increasingly competitive global marketplace, and to customer requests for integrated solutions, the Chicago Rawhide brand, predominantly known as CR, has transitioned to SKF.The transition is part of the company’s goal to create one global, universally recognized SKF brand. The products, employees and facility locations remain unchanged, assuring customers the same high level of quality and service they have enjoyed previously.

So the CR seals may now be ceased production.

SKF = same number, different Co.

Tony,

SKF acquired Chicago Rawhide many years ago. CR seals are not ceased production, it is merely a rebranding of well-known line of products. If I am correct, the numbers are still the same, except for the "CR" bit. Any authorised SKF distributor should be able to help you out.

Yeah, thats what I meant.

Look for SKF with same no. as the CR.

This is embarassing. I have a pair of NTN 33275 bearings that I bought when I was working on the rear end, what seems like decades ago now. I think I bought them especially for when I would be doing the front, I.E: now. Heres the annoying bit. I cant recall WHERE they are meant to go. I looked at the spreadsheet with the modern part numbers, but that says they are Bearing, Front Wheel, Inner 6". Could someone tell me if that is actually these bearings. For some reason I thought these may have been for the ends of the differential set.

Hi Tony,

Looking at the Timken bearing cross reference catalog online SKF33273 is the same number Timken equivalent, ie.Timken 33275.

Since the CMP Maintenance manuals almost always specify Timken bearings it appears Timken No. 22275 is used as the front wheel inner cone on 6" steering ends according to my manual.

Hope this is of some help.

Cheers,

Hi Tony,

Sorry, did not want to give you a bum steer. That was a SKF number cross-referenced, not a NTN number. And it was 33275 not 33273. Mondayitis on a Tuesday for this guy!

Could not find any SKF to NTN cross reference on the net but checked the dimensions of both NTN and Timken No. 33275 and they both seem to be the same size bearing.

Cheers,

Thanks mate! I have also been enlightened by a fellow MLU'er that it is used on the carrier part of diff assembly. It would make sense to have one bearing fit more than one purpose. I am slowly amassing quite a list of bearings & seals that I want to replace.

I discovered yesterday that the welded on brake backing plate (driver side) is also marked RF. So is the left hand side! That means I already have my replacement for the one I will be cutting off, but will need to find a LF one.

I'll post a few photos of the last couple of days work, later tonight, including the damage I found around several teeth of the crown wheel. Something catastrophic has occured some point in the past, but seems to have been rectified. No obvious issues found by me and my father-in-law yesterday. We suspect a big failure of one or both bearings, causing the crown wheel to smack into the casing in two places. Yikes! Must have made quite some noise when it happened. Lots of metal filings in bottom of the casing.
