Four-row cylindrical roller bearings are usually mounted on the neck in an interference fit and are especially suitable for rolling mill applications with high steel rolling speeds. The low cross section of these bearings allows the use of a relatively large roll neck diameter compared to the roll diameter. Due to the large number of rollers that can be loaded, its radial load capacity is very high. Four-row cylindrical roller bearings can only bear radial loads. These bearings are therefore mounted together with deep groove ball bearings or angular contact ball bearings or tapered roller bearings of radial construction or thrust construction, which bear the axial load. The four-row cylindrical roller bearings are of separate construction, that is, the bearing ring with integral flange and the roller and cage assembly can be installed separately from the separate bearing ring, or all bearing components can be installed separately. This simplifies bearing installation, maintenance and inspection to a considerable extent. The bearing can withstand a certain limit of axial displacement of the shaft relative to the bearing seat.
