I am rebuilding a Bridgeport J - head (machine serial # 101216 ; 1967 vintage / J - head serial # J - 99718 ; not sure if it is original to this machine).
The following Bridgeport part numbers are from April 1981 / M - 105H catalog.
So far I have removed the following pulley and bull gear bearings (not yet on the spindle bearings):
Norma thrust bearings (qty. 2) part # XH 125 / Bridgeport # 1190230
Norma thrust bearings (qty. 2) part # XH 124 PP / Bridgeport # 1190232
and Norma bearings (qty. 2) part # 203 - KK / Bridgeport # 1180235
Could you offer any interchange information (part numbers) / preload specs. as these are getting replaced. I have read previous posts, but no actual bearing house part numbers are interchanged to these relics.
Your assistance is GREATLY appreciated (special thanks to Den for sending me here).
Thanks in advance to all that respond,
Tom
