Homework Help: Thrust ball bearings

  1. Dec 29, 2009 #1
    This isn't a homework question, but something I'm interested to know that my engineering corespondance doesn't mention.

    I'm aware there is both single direction and double direction thrust ball bearings but can any one tell me why can a single direction thrust ball bearing only be used in one direction?

    Some bearings can take thrust in one direction only, such as http://commons.wikimedia.org/wiki/File:Tapered-roller-bearing_din720_120-ex.png" [Broken]. Click on the links above to see pictures.
