Cylindrical roller and raceway are in line contact, radial load capacity, both suitable for bearing heavy load and impact load, but also suitable for high-speed rotation. Cylindrical roller bearing raceway and rolling body geometry after the improved design has a high bearing capacity, retaining the new structure design of the edge and roller end face not only improves the axial bearing capacity but also improves the lubrication condition of the roller end face and edge contact area, which improves the bearing performance. These bearings are mainly used in medium and large electricmachines, generators, internal combustion engines, gas turbines, machine tool spindles, reduction devices, loading and unloading machinery, and various industrial machinery.
