Don’t be shy, sign up and come, or plan your own meetup!

Jacobs Super Chuck or clone?

Pretty simple formula for keyless vs keyed chucks. Keyless is for 3/8s and below IN THE MILL only . Lathe , always a SSB .

I don't hesitate to use 5/8 keyless in my mill and do it often with no issues.

What does SSB stand for?
 
Oh . SBB Jacobs . One too many beers on the beach . :rolleyes:

I'm still not finding anything. The closest I can get with Google with any repeatability is JBB for Jacobs Ball Bearing. If I stretch it a bit, I can also get Super (Jacobs chuck) Ball Bearing.

I'm still somewhat amazed that the cheapo I bought (see earlier post) has bearings and even more impressed at how smooth they are.
