Radial and thrust loads are defined by the angle or the direction that the load is applied in relation to the bearing; In the case of cam followers: a radial load is perpendicular to the axial center line of a bearing, a thrust load is parallel with the axial center line of a bearing; Any variation from the angles between the two types of loads is considered a combination load and must be properly calculated to select a bearing type or determine theoretical life; Contact Application Engineering at (800) 626-2093 or via email at for more information.
