<VV> Axle Bearings

[Frank DuVal]

If you mean you can rotate the bearing housing axially only 1/8th of an 
inch, that is not enough. But if you mean you can push the bearing 
housing an 1/8th of an inch along the axis of the axle, that is too 
much. i.e. the bearing housing should not move any up and down the axle, 
but it should have lots of freedom to rotate in all the directions the 
barrel shaped roller allow.
