Atlas 618 Spindle Bearing replacement! 

Replacing the spindle bearings in the headstock of my Atlas 618 lathe. These are Timken bearings and the information on which are needed is sketchy. Here is what I found for my 618, with Tapered Roller Bearings:
Nomenclature: CONE = BEARING and CUP = RACE
Chuck side:
CONE: 07100
CUP: 07196
GEAR OR REAR SIDE:
CONE: 07079
CUP: 07196
The two bearings use the same race (CUP) so order two of those and the other two bearings (cones) and all are TIMKEN numbers.
Enjoy!
