axial bearings

Can I work out how much axial clearance I have in my bearing? Most bearing manufacturers never give this information in their catalogues. It is suprisingly inexact and does not fall into any international standards. As a very rough rule of thumb it is eight to ten times that of the radial clearance. We would strongly recommend that the advice of the bearing manufacturer be taken on this as other factors such as heat expansion either locally or ambient, load conditions, rolling elelment type etc will all play a part in the axial movement
