Need Help! Need two 12mm 4 Bolt flange bearings - CNCzone.com-The Largest Machinist Community on the net!

I have looked on various sellers on Ebay and Amazon and cannot find any 12mm 4 bolt flange bearings, tons of 1/2" though.

I need two of them.

Can anyone tell me where I can get a couple.

Thanks

Why not just go with 1/2" http://www.thebigbearingstore.com/se...-Flange/Detail

and make it work? 12mm is what, .47? 1/32 isn't a lot of play especially with 2 set screws.

Thanks for the suggestion but as you say 12mm = 0.474" that's 0.026" smaller than 0.500".
This would put added stress on the ball and the flex connection, I want to build as best I can.

If I can't find a 4 bolt 12mm flange then I have two options, (1) make a flange using HDPD (SP???) or (2) turn the 12mm portion down to say 0.250" and sweat a sleeve over it to bring it up to 0.500". The latter is what I'm leaning to.

See Drawing below.

When you are building out of found inexpensive parts there is always challenges.

Berry Bearing Co. Has what your looking for. We had alot of metric machines at the plant. We called them and could get the bearing by COB.

They don't have a web page that I could find. Also try other bearing suppliers in your area.
