Proprietary Bearings may be a reason for the scrap pile

[Janderso]

I posted this project in , What did you do in your shop today.
This subject in my opinion, deserves all big guns online.
I have never seen bearings like this. I assume the spindle cartridge contains standard bearings.
The product,
Caned-Otto #16 precision drill press. It’s a high quality, high speed product made by the Cincinnati Lathe & Tool co.
It’s old.
Check out the bearings, the bushing is the inner race for the 5 sheave pulley.
That’s the other deal breaker, where am I going to find a mate for the drive end? It came without a motor.

Any chance you could press fit a sleeve inside a common bearing to replicate these?

Make a sleeve to fit the inner race of new bearings as suggested by rabler, and use Green Locktite to bond together.

I was going to suggest the same.
The one on the left looks like a sleeve that is pressed into the bearing
the one on the right, you might have to go by the outer race and find a bearing that leaves enough room on it press in a new sleave to mimick that bearing. I think it's worth a shot. ALSO
try these guys, they find hard to find bearings... http://www.asapbearings.com/index.html appears to be having an issue now, but try again Monday or Tuesday.

Did you read this post a couple of days ago? 1st post is about hard to find bearings

I have a shout out

I want to tell of a good experience. I don't normally do this, I dont even right reviews online. The way I see it; I see an item on line, I pay for it, they send it, and the transaction is over, usually anyway. I dont feel it necessary to tell everyone how I feel, or what I was eating, or...

they appear to be standard 202 bearings with sleeves pressed into the ID,
the idea could certainly be replicated

Don't give up on the project just yet. I'm out of town right now and won't be returning until the end of next week. When I do get home I can look up the bearings in a set of catalogs I used for machine design. There are 7 volumes each about 2" thick. They spec out and cross reference supposedly all bearings made from about 1930 to 2000. I've used them in the past to locate hard to find precision bearings in the past. If I remember correctly they were published by the now defunct International Bearing Institute. The standards have been incorporated into the ISO system, but it's usually a nightmare to find them under the new system

In many cases the original part number has been superseded several times between the original introduction and the latest version. They could also be made by different manufacturers with different part numbers due to slight differences in materials.

It would help if you could post a picture of each with the part numbers as legible as possible. A clear picture of each side of each bearing with as much grease and crud removed as possible would be great.

Often times I have contacted a business called "Locate Ball Bearings" with a list of cross referenced part numbers to find obsolete and hard to find bearings. They've been able to come across several times and with prices far more reasonable than anyone else in the business. This company buys out overstock and obsolete stock as well as buying out failed or closed businesses. They literally have hundreds of thousands of bearings in stock.
