Hi All,

The non-chuck end, outside, whatever is a 30211J, I scored an ABEC 7 version for $150 - perhaps 'scored' is a bit to cheary, maybe 'got soaked for' is better to state that, any way, will try and do the same with what ever the other end is perhaps 30212 but I won't know untill I take it apart, and I am not even sure where to start...

Good info Ray. What's the difference between the one you got and these?

A bit more information" not sure about the chuck end...

"30211" bearing, which is listed online as 55m I.D. and 100mm O.D.
"D7211" (outboard) "55mmx100mmx23mm" and "D7212" (inboard) "60mmx110mmx24mm" a.k.a: "30212"

May help

Pretty sure those are Class 0/ Normal. ABEC 9 is 'wicked good' vs ABEC 1 is down right crappy, and the cost doubles or so between each class. The $150 I paid would have been closer to $1000 had I not done my midnight run at Fleabay (for 1 bearing), and paid going rate.



The above is from Wikipedia

ANSI Standard*	DIN 620*	ISO 492*
ABEC 1	P0	Class Normal
ABEC 3	P6	Class 6
ABEC 5	P5	Class 5
ABEC 7	P4	Class 4
ABEC 9	P2	Class 2

Got it. Thanks for the info!

Ok, I will make some copies of the manual for everybody. There are three books, the parts manual, the operating manual, and a factory checklist with actual measurements for my lathe. What they spec and test for may be amusing, so I will copy anything I have that seems remotely interesting and not readily downloaded.

PM me your mailing addresses.

I'd like to get in on that as well, will PM you my mailing address. Seems only fair though to pay you postage at least.

Hi All,

Been looking at this lathe a bit and am trying to decide if the bearing need to be replaced - probably not. Also trying to figure out how to do the actual measurements - positing the DTI, etc...

The alignment information is very timely - Thanks Curt!
