I'm trying to identify (what I am assuming was) a internal grinding spindle, has anyone come across one of these or happen to know what type of machine it may have came from?
The arbor has a 20 degree included angle, the draw blot is a left hand thread, it appears to have been driven by a flat pulley held on by a right hand thread retaining nut, the OD of the main body is 2.750 inches, the only markings I can find are " AP465 BI "
The front bearing has hand engraved markings that look like they where done with a engraving pen, outer race "od/7.0000" inner race "20,000"
The back end bearing is installed in a keyed collar with 8 spring for preloading, the preloading is fixed by the strength of the spring (not adjustable).
Though it has suffered some external rust damage internally it's in excellent/perfect shape, it's a really well made piece of gear, I'd like to use it for a project but it would be nice to know where/what it came from.
Any help would be appreciated
