[Boatanchors] Bearing identification

[WA5CAB at cs.com]

Brian,

I would generally agree with Price.  Although if they are sealed, you won't 
be able to replace the grease.  But if they are any good to begin with, you 
aren't going to hurt them by opening them.  If they turn out to be inch size 
precision ball bearings, you won't have any trouble ID'ing them.  Those have been 
made in many standard sizes since before WW-II and although different 
manufacturers used slightly different prefix and suffix letters to ID seal or shield 
details, the basic bearing number is standard.
