standard combined roller bearing

By considering the moment-balance of the sliding system, the Hertzian Pressure exerted on the steel profiles can be calculated. In most applications it is the Hertzian Pressure that is the limiting factor. This is the "pressure" at which the point load exerted by the bearings begins to deform the rails (steel profile).

1) Calculate the 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.

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