The Stovebolt Site Forums The Shop Area General Truck Talk Roller Bearings

There was a discussion here recently about converting to roller bearings, part numbers and all...

Using numbers found here I had ordered some from my local parts guy for my 56 but they didn't fit. Decided to order them from Chevy Duty (still had a store credit)... put them in last evening and they fit great.

For reference:

Part # off of the bearings themselves so you can try your local supplier:
Inner w/race: 909052R
Outer w/race: 909001R
Mfg is MBS (Japan I believe)

Yup, numbers are close to what was provided in my order from CPP:

Seal: National 6064
Inner: MBS 909052R
Outer: MBS 909067R

All fit fine including the seal.

Cross references to Timken
Seal 6064
Inner B52
Outer B01

I have wondered. Was it really worth the switch?

Don't know yet train.. but I'd been having some problems with the ball bearings so did the switch on the advice of my mechanic who has never let me down in over 50 years...

Other posts have argued for and against so search could probably bring up that discussion.

Thanks for the cross reference. Good info for the future.

train, Larry - those are the ball bearings
other brands:
inner - SKF B52
outer - Chicago Rawhide B67
seal - CR 18772 [NAPA 49412]

Well, I DO know that the numbers I gave at the top of this post are definately rollers because I took them directly off of the bearings.

Good to have the cross reference Red!

OK.

I'll have to recheck my cross-ref abilities.

The local bearing company said those were ball bearing numbers when I checked with them. Surprise, surprise--they were wrong! Just like you found out. Guess the cross refs aren't always on the money.
