What bearing is this? (belt grinder)

[kruegdr]

Awhile back I proclaimed an uncalculated "I ****" moment, and was promptly cursed. I broke a bearing housing during disassembly of a belt grinder that was getting tossed at work.

In the process, I pulled the bearings to replace them and they're quite strange. What type of bearings are these?

A Google search pulls up a Chinese Timken site, and another gives a Polish site that calls them external self aligning bearings. Their 1010 series seems close. (I do have mating collars)

Where could I get these in the US?

The grinders only identification is "AB 541"

Thanks!

Try applied industrial technologies. Did you see this Timken page? I googled spherical cam lock bearing. These are often used in pillow block bearing setups.

This maybe?

Thanks ORJ. Those links didn't come up when I searched. I had no clue what to really search for.

Those pages you sent seem to have bearings that have a broad crown on the outside. The ones I pulled out have parallel sides. (Picture 2)

Here was the Polish site I found. (Came back inside to the desktop compy)

Looks like an eccentric pillow block insert. Call Accurate Bearing at 800-323-6548 with the number. Found it in a Timken catalog. SM Industrial unit.

Type A bearings are cylindrical on the OD (what you have in your hand).

Type B bearings are spherical on the OD ( what the other guy posted).

That looks like a self aligning Bering to me
Not that hard to find. You need to be talking to a bearing supplier, give them the number on it and ask price and availability

Price is what it is
Availability will be do they have it stock or do you have to wait

Thanks Affende, I didn't even notice the crown on the drawings last night.

Well, after many months of semi-passive searching, Pueblo Bearing was able to find the parts for me. A Bearings Unlimited CSA202-10 was the ticket I needed to get the belt grinder back and spinning. The only thing I need now is a shaft coupling, which is on order from McMaster.

Thanks to all who helped, and I hope that Pueblo Bearing can get some love. Their staff was very knowledgeable, patient, and got it done.
