New Rotors Come with Bearing Races Installed?

Dibbons · Mar 5, 2020

Working on a '72 SSP. It's been ages since I purchased a rotor (if I even have). Mine have some deep scoring so I don't believe they can be cleaned up.

I can't find rotors locally so will have to have a pair shipped from the USA. I just can't picture if the rotors always come with the wheel bearing races already installed? Where do you guys purchase rotors? I know Summit has a listing. Thank you.

Any Chrysler rotors i have bought recently have the races in them. You guys have rock auto?
I have even found drilled and slotted rotors on ebay.

New races, yes. New bearings, no. With new races, if your bearings are good, I see no reason not to repack and use them. Do look at the races in your old rotors closely. If they have any unusual wear, replace your bearings too.

IMO...
Rotors USUALLY DO NOT typically have bearing races (in Timken bearing nomenclature) the race is called the cup and the other half of the bearing is called the cone. In inside bearing assembly is almost always larger in both the inside diameter and outside diameter than the smaller outboard bearing assrmbly. The cups sre pressed into the rotor assembly and the cones are packed with grease snd assembled to the spindel. Summit is a good source for both bearing assemblies and the seal and grease....Timken markets a bearing grease and Summit sells it. I think that Dr. Diff also is a possible source. Be specific about your requirement. Just my opinion of course.

The last few sets I bought do have races,although I always knock them out because they have been cheap Chinese crap. Cheap insurance to just replace the bearing/race assemblies with quality pieces.

^^^This is the correct reply.^^^

I like to use sets, (cup and bearing) when it comes to roller bearings. I won't even mix them up when I unbox them. Tolerances can change during manufacturing and one batch could be different from the next. Just my OCD

The Chineseum world clearly leaves A LOT to be desired !!!! (And that is an understatement !!!)
I have N.O.S. U.S.A. made Hub & Rotor Assemblies and U.S.A. made Bearings & Seals....
You can respond to me here .....
