Cylindrical roller bearings have high bearing capacity. The new structure design of the flange and the end face of the roller not only improves the axial bearing capacity, but also improves the lubrication condition of the contact area between the roller end face and the flange, and improves the service performance of the bearing. It can withstand large radial loads and is suitable for high-speed operation, such as large and medium-sized motors, locomotive and rolling stock, machine tool spindles, internal combustion engines, generators, reducers, rolling mills, and lifting and conveying machinery.
