As the title suggests, I am woefully uninformed about tapered spindle bearings. I need to replace the bearing in my mill a 1956 south bend ram head, 1 hp, 1800lbs sorta a Bridgeport model 1 copy... her highest speed is 3750rpms, I never checked, it does seem to move though...
After I have studied the parts breakdown, and attempted a couple trial breakdowns, I will finally pull the machine apart...
As for spindle bearings, I am pretty sure I will not find any information other than what I have now. I am hoping to find the original numbers still stampede on the bearings... what about ratings for the bearings, my lathe came with class 5 nsk tapered bearings, will the numbers on the bearings indicate that kind of information or is that something I need to let the bearing dist know.
I am watching you tube videos on guys doing spindle bearing on Bridgeport machines, any chance that will relate to what I need to do?. I am curious on preloading and install of the direction of the bearings, is it common for these to need to be installed very specifically?
Will a heavy hydraulic be required or suggested?
Lots of questions, and I have more. I want this to go as smoothly as possible
Thanks for all help and suggestions.
