Ballnut question????

Hi.... recently been doing some building and using ballscrews, and i was wondering if the orientation of the ballnut was important.... let me explain, should the return tubes be in the upright position (to help retain lubercation) or ?

Also I still not sure what the "proper" lube is for the Ballnuts, keeping in mind, that for all practically purposes, the ballscrew would be in a controlled enviroment, with wipes. Do the manufactures of these ballscrews system have there own special lubes?

Thanks in advance,
Russ
