Rear Upright/hub Bearings

[drivetrainUW-Platt]

Just out of principal I am thinking tapered rollers would be far superior over straight rollers. Can someone second this? I think I will be looking to use one 30 ID x 20 wide and a 35 id and 20 wide tapered roller.

Last year we didnt run tapers and didnt have any problems, but it just makes more sense with the cornering forces we see in these cars.

TRBs still slip because the contact angle is too low, use ACBBs.

Sorry, I am familiar with both designs, but what do you mean one will slip? ???

Best,

Whats this about slipping and what is an ACBB?

Angular contact ball bearing. I'm curious about the slipping too.

We're using an ATV diff and CVs similiar to what I think you're running Mike. We also ordered the hubs and hub bearings from the ATV. We'll be modifying the hubs and using the stock bearings. The stock bearings are DOUBLE ROW angular contact bearings that are capable of handling thrust and axial loads.

the contact angle is too shallow. draw a FBD and you'll see

Conor, please post pictures of the stock hub, cv joint, bearing, and upright please.

I am having a hard time sifting through the different part numbers for the SKF angular contact bearings.

I am looking for a 40ID 80OD bearing, I think they were 18mm thick. There must be a lot of different configurations of sealing and what not. Anyone familiar with their numbering?

[Mark TMV]

Look for wheel bearings. It is a pain to track the part numbers sometimes, because most of the time they're direct OEM replacement.

Try this for reference: http://www.sonexauto.ru/cat/stup/sheet003.htm

Or a more expensive alternative: http://www.pegasusautoracing.com/productdetails.asp?RecId=294

Mike - 40 ID, 80 OD, 18 thick is part number 7208 for single row angular contact. From there you can get different options ie matched, grease type, cage type.

I used to work for SKF so I have one of there cataloges. I can't translate their numbering because I could never remember it. You multiply the first numer by 5 to get the OD class, the second number to get the IS, etc. or something like that.

If you're running the Honda setup, trying checking at hyperparts.com. You can use the OEM bearing part number and order the exact same bearing in a sealed version.
