Has anyone checked the WW Grainger catalog??  If they don't carry it, you 
probably don't need it.  US Tower gets them from somewhere and I'll bet they 
are an off the shelf item.  They can't sell enough towers to have them 
manufactured special.

Rich,
 I should have read your message before posting.  I was going to call US 
Tower about the bearings too.  I have a HDX589, the K10 bearings must be 
what I need.
Now to find some !!!

 I found that the bearing inside the sheave is a K10 bearing.  Looks like a 
KP10 bearing might work but these seem to be REAL hard to locate.
 Thanks for all the ideas from the list.  With the amount of towers out 
there, I was hoping for a stock replacement solution, but looks like this 
is a bit more complicated...or expensive.

Subject: [TowerTalk] US Tower HDX-689 Sheave replacement
 Im looking for the 5 inch OD Pulley Sheave for the HDX-689. This is for 
the ¼ in cable.   I need to order a few of these as I'm replacing all the 
cables on the tower right now.  I know US Towers had them, but wanted to 
see if anyone else has replaced them from another vendor for a better 
price.
Thanks...
