# How to choose between two possible arrangements of tapered roller bearings?

I don't know how to decide between the $$X$$ and $$O$$ arrangement, i don't have any specific example at this moment, but i want to know.

Catalogues offer only some basic calculations. I'm not quite sure if there any guidelines or instruction exist, i have already consulted many books, but so far my researches failed to help me justify the choice between the two arrangements.

The arrangement on the left is often used for fully floating hubs on vehicle axles, as the end float is easily set and controlled.

• Thank you, this is very specific example, however i'm searching for a more general guidelines. Apr 28 '19 at 11:05
