    Roger, thank you for cutting to the chase. You  are entirely correct but 
hardly anyone is aware of this and only the Orion  even mentions it in their 
owner's manual. While I haven't seen any  catastrophic failure trends with 
"floating" rotators, they are all designed to  have some preload to seat the 
bearings in their races.
