The four cylindrical roller bearings and six cylindrical roller bearings almost entirely for the roll neck rolling rack, roller and rolling press. Compared with other roller bearings, the friction of these bearings. These bearings are usually installed on the roll neck, interference fit, particularly suitable for rolling high-speed rolling mill applications. The low cross-section of these bearings allows the use of relatively large compared with the diameter of the roll roll neck diameter. Can be put into a very large roller, radial load capacity is very high.
A considerable extent simplifies the bearing installation, maintenance and inspection. Bearing can withstand a certain limit shaft relative to the bearing axial displacement. The four cylindrical roller bearings with a cylindrical hole, some size bearings can also supply with a conical bore. Bearings with tapered bore can be adjusted during the installation process to get a certain amount of radial internal clearance or determine the pre-load.
