   You're not kidding that bearing suffixes are confusing as all hell!   
      
   I suspect for my $150, the Chinese bearings my motor rebuilder put   
   in are likely the cheapest he could get away with. So it behooves   
   us to rebuild our own motors, where we can put in the best bearings.   
      
   The trick is to figure out *what* is the best bearing to use!   
      
   To get a handle on what the bearing needs to be, I called the   
   AO Smith technical support hotline at 800-262-6484. The lady from   
   Tennessee knew absolutely nothing about bearings, but she kindly   
   read off the specs for me off the motor datasheets.   
      
   The bearings are made by NSK and they list the part numbers as:   
    QC1102 1.65HP motor: 6203 double sealed NSK 6203WC3E CLKEEMSM   
    SQ1152 2.20HP motor: 6203 double sealed NSK 62032RSGC3ETDEEMS9   
      
   Googling for those NSK numbers, I don't find anything useful.   
   But, when I google the part number (604005-001), I can find it as:   
    $19, 62032RS http://www.inyopools.com/Products/07501352012909.htm   
      
   So, now that gives me 6203D, 6203V, and 6203RS as the bearings,   
   all of which are different - which is driving me crazy.   
      
   What I'm doing now is reading the NSK booklet titled:   
    "The ABCs of Bearings", located here:
