  • Experimental measuring procedure for the friction

    The bearing must have a minimum axial load in order to work with low friction. In case of a low axial load, care should be taken to ensure the preloading of the bearing. For cases where the four point bearing is used only as a thrust bearing, a large radial clearance must be provided in the housing for the outer race.
