They are usually "standing" and crisscrossed to provide lateral stability while still rolling.

Leitz Laborlux s need help

I am fixing the leitz laboelux s focusing mechanism but the pellets are cylindrical and now I didn't check well if they go lying down or slanting.
What is the correct way to put them please ?
Thanks

I think you will likely want the compensating eyepieces 167 or 168 with that one, or perhaps the planoscopic.
