Make contact with a local bearing supplier - I know its a bit last century, but they often have vast knowledge of who does what or who could take a standard bearing and make iit what you need. I wandered into mine with a Japanese bearing from a German gearbox bolted to an Australian engine in an Italian car - and she recognised the number, told me she's sold the last one on the shelf yesterday and she was sorry, it would be the afternoon before she could get another . . . the afternoon of the same day

The bearings on my Dyno are like that, they are in the pillow blocks, pin is to stop rotating in the mount but allow flexibility. Mine also have a slot and pin holes to allow grease nipples to function.
Unfortunately I couldn't find exact replacements so had to go with no pin and no groove.

I tried drilling some as a boy making my first go-cart.
Remembered that lesson!
The pins in these are about 2mm dia and protruding by 2mm.
2mm roall pins would do the job and 2mm copper wire would presumably make it easy to edm a hole in?
Another wicked thought I had was to put a tack of weld on the bearing and file it down...
I can see that ending badly but I could submerge most of the bearing in oil and tack it really quickly

Easy to drill with a Stellite drill. 3000rpm and no coolant. Job done....

The bearings on the tool holders for the Chiron had a pin in them to locate into a brass disc which was used for braking the tool when it was changed. They were also a special in that the width of the bearing was non standard but me not wanting to pay well north of £100 for a bearing, especially when I needed 20 or so, I worked out I could get away with using a standard width bearing (3 or 4mm less) and just make up a shim to make the brass disc a tight fit. Seems to do the same job and the bearings were under £10 each which suited my pocket a lot better 
Obviously of absolutely no use for you or your situation but I felt like typing it out anyway as I still smile at saving myself at least £2000

Those are the ones!
At £32 for the pair it's a bit better than the £55+ I have been getting quoted from the dealers!
Although I could buy 2 roll pins for a pound each and have £30 left over to go towards a edm... this is why I need 3 phase...

Just read this back to myself. What an idiot I am, look at the photos, the bearing number is shown and the sizes I can get from there.

Sorry, I thought I had answered that!Just read this back to myself. What an idiot I am, look at the photos, the bearing number is shown and the sizes I can get from there.
It's a little mercuary outboard engine.
I have got the part numbers and think I have found at least one suffix that adds the pin.
Let me know if you need any of them!
