Default Race or Std Cosworth bearings

Guys

What are the differences betwen both bearings?

Race are the sb000 series and the std are the PRs series..

So they are different...

What are the pros and cons on using each one?

Thank for the advance

DJ

The biggest difference I know of is that the race bearings are set up for extra bearing clearance. This makes for extra wear if you're just puttering around, but on a track the extra clearance is critical when things get hot.

Gee, you'd think Cosworth would make this information readily available. Have you called them to ask?

I found a web page that said the difference was .001" clearance, but of course I can't seem to find it now that I'm looking for it...

Edit:

I'm pretty sure these are what Cosworth is using for their race bearings. I'll have to look at the part numbers on my bearings at home, as they should be the non race version.

save your money and just buy from the source. Cosworth uses ACL bearings.

But the Cosworth bearings are stamped with a Cosworth logo and that gives them magical properties...

I got the Cosworth bearings because they were readily available and in stock at the shop I was buying other parts from. Combined shipping and ease of ordering FTW.
