Power loss and load carrying capacity of loaded ribs of radial cylindrical roller bearings

The assignment of cylindrical roller bearings is widely spread in mechanical and automotive engineering. Radial cylindrical roller bearings have been proven as variously applicable and economic bearing arrangements. With ribbed inner and outer rings these bearings permit the transmission of axial load in addition to radial loads. The axial load is induced on the rib of the inner or outer ring and transferred by the roller end faces to the opposing rib. In comparison to an only radial loaded bearing there are additional friction losses in the contact between the rib and roller end face as a result of sliding. `The limiting factors for the permissible axial load are high temperatures which can cause smearing and seizing, rib breakage, fatigue and wear.
