I've always thought the roller bearings must be cheaper to make. 1948 3/4-Ton 5-Window Flatbed Chevrolet 34 Years.

New Departure # 9726 (inner) and 9725 (outer) were original equipment. These were known by their GM part numbers 909726 and 909725. New Departure (among others) also made a direct replacement roller version of these bearings numbered 909726R and 909725R.
Note that the adjustment procedure for roller bearings is very much different from ball bearings.

I would not have done that but will leave them in there. We have 4 Chevys with the ball bearings and never had a problem, it might that I do maintenance occasionally. | | | | | Joined: Sep 2009 Posts: 5,962 Gearhead, Stovebolt Tech and Parts Tracker, Mod for Swap Meet and GTT | | Gearhead, Stovebolt Tech and Parts Tracker, Mod for Swap Meet and GTT Joined: Sep 2009 Posts: 5,962 | .

Thanks Bill. You are right that the ball bearing numbered units mentioned are listed for both Chevy and GMC 3/4 tons. I did a pretty thorough web search and found none of the "roller style" replacement bearings (inner or outer) to fit 3/4 ton Chevy's or GMC's currently available. In fact I couldn't find a single cross reference to any roller style bearings for these applications. Just lots of the original style "ball bearing" units which seem to be pretty widely available. Hope Bristol's Tree S is okay with using original style bearings as there doesn't seem to be an alternative out there.

Even with the sorry grease we had in those days, ball bearings ran almost forever. If I needed wheel bearings, I would find some used ones. With today's grease they will run forever. | | | | | Joined: Jan 2022 Posts: 197 'Bolter | | 'Bolter Joined: Jan 2022 Posts: 197 | Is there a way to convert factory front wheel bearing to roller bearings While keeping the 8 lug wheels?

Having "deep pockets" is an understatement at those prices IMHO though. I'd have to stick with tried and proven original ball bearing sets. A person could buy a whole bunch of those for what would be handed over for these.

You can' t use dimension bearings because the inner one needs something for the seal to run on. The ball bearings are spendy enough already, $60+ last I looked. IIRC they also fit Buicks from the 50s. 1951 3800 1-ton"Earning its keep from the get-go"In the DITY Gallery1962 261 (w/cam, Fenton headers, 2 carbs, MSD ign.), SM420 & Brown-Lipe 6231A 3spd aux. trans, stock axles & brakes.
