Choosing Bearings and Mating Steel Profiles

Selection of Bearings

There are two seperate considerations when deciding which bearings to use. These are:

a) Moments - the force on the bearing depends on the distance between i) the load and the point of suspension and ii) the bearings and the point of suspension.

b) Hertzian Pressure - the pressure on the profile should not exceed the tensile strength of the profile in order to prevent depressions in the rails.
