What's this called

[PacWest]

I'm doing bearings on a custom axle.
I believe was on a motor home.
These were stuck on the spindle.
No part number.
The bearing was riding on it.
No parts or bearing pictures show them.
Appreciate any help.

Thats the inner race from a taper bearing that looks like this. You dont see pics because it failed and comes assembled as shown below

Thank-you, very much

There is a slight chance of a bearing number being etched on the inner race flange where your fingers are making contact. Otherwise take it into a bearing supplier and they can get dimensions with a micrometer and fix you up. They see stuff like this all the time. Chances are the counter person will "eyeball" it and have a new bearing in a box on the counter in 3 minutes.

I see you are from Seattle. Try Bearings Inc in the industrial district.
