Having obtained some from aircaft control cable pulleys marked "Boeing"
the ORIGINAL use was just that. One crank up tower maker actually had
pulleys marked Boeing with these bearings rusted solid that I replaced.
With the wider inner race the pulley flanges and cables don't rub on
the mounts.
Note the 1998 date on the ebay box. Fafnir doesn't make these any more
AFAIK. In 1989, I asked them to make an out of production bearing about
this size they said, "We can do it since we have the prints. $50,000 for
set up and 1000 bearings". I found away to substitute.
Best to soak these in oil for a while, since the grease is now 34 years old.

Guess I don't know what I am doing.
Go to eBay and do a search on " Torrington Fafnir Aircraft Bearings KP8
FS428 New - FREE shipping" This worked for me.

Here is a link to eBay for some K8 bearings. Price is $17.95, shipping
included. The seller says "bearings" so there may be more than one
available.

You can't beat the price anywhere.
