The..312 is the weight. It is a R8 bearing
Is that a flippy cap on your 445
That is mighty cool looking, good luck with the project. If you need any machineing I would be glad to help.

I've ordered a few seals from these guys, they were the only ones I could find with reasonable shipping to Canada, they beat the price of every bearing/seal supplier I called here.just some more GARBAGE, Boca bearings is a good source. but some may find it garbage, your to you odd bearing is very common garbage.

My quick look shows the R8 bearing to be 5/16" wide. I need no more then 1/4" wide.
Then I see a R8 listed that is 1/4" wide. Go figure. https://www.vxb.com/R8-Open-Bearing-1-2-x1-1-8x1-4-inch-p/r8-open-bearing.htm
Then a S5K bearing https://www.vxb.com/S5K-Open-Bearing-1-2-x1-1-8x1-4-inch-p/s5k-open-bearing.htm
[emoji22][emoji24], what's the replacement idea?Just got off the phone with partstree and the rings for the 5200 5400 85cc are no longer available
I had a look at the NSK catalog and the R8 bearing they list is .5 X 1.125 X .25 Another R8 is 5/16" so I'm assuming they come in both sizes.
If you have the inclination, you will find the R8 on page B7 of this NSK catalog. The bearing weighs .040 lbs or 18.1 grams

Maybe see if the ring groove could be opened up for a regular cast ring? Of course that ring stud will be a problem.Don't have any idea what to do.
