I have a general idea of what they do from the site below
http://en.wikipedia.org/wiki/Rolling-element_bearing
However, I would like to know what are some examples of this, as well as some info on what the ‘cage’ is, etc. If anyone can provide a diagram, 10 points will be awarded without hesitation.
Thanks in advance

2 the “cage” keeps the rolling elements from grinding into each other
for information, check out SKF, Link-Belt, Torrington, Dodge, any bearing catalogue
