Cylindrical roller bearings have bigger load-carry capacity after amending the raceway and the geometry of rolling elements, and the new design of ribs and roller end surfaces improves lubricating conditions of contact area between roller end surface and ribs, increases bearings service life. These bearings are mainly used in medium and large size motors, electricity generators, internal combustion engines, gas turbines, machine tool spindles, deceleration devices, unloading and lifting machines and other industrial machinery.
