Lathe spindle bearings CYCLONE

Post by Maszynotwór » Tue 24 Sep , 2024 20:30 pm

Hi.
I got a CYCLONE lathe for a general overhaul. I just disassembled the spindle and I have a problem with the bearings. The diagram on the forum shows 1 deep groove ball bearing at the back and 2 SKF 7211BEP angular contact bearings, with rings between them (probably regulating the preload). In my lathe, there were 2 ball bearings at the back, with C3 clearance, and probably paired English IBC 7211 ETPAP2HUL ​​bearings at the front. There are signs that the spindle was disassembled and someone was messing around quite brutally. I have no idea how it is actually supposed to be bearing. Can anyone suggest something?
