The cylindrical roller is in linear contact with the raceway and has a high radial load capacity. Suitable for withstanding heavy loads and impact loads, as well as high-speed rotation.

The raceway and rolling elements of cylindrical roller high-temperature bearings have geometric shapes. After improved design, the new structural design of the retaining edge and roller end face not only enhances the axial load-bearing capacity of the bearing, but also improves the lubrication conditions in the contact area between the roller end face and the retaining edge, thereby improving the performance of the bearing.
