(3) Four row cylindrical roller bearing
Four row cylindrical roller bearings are mainly used on metallurgical equipment as main roll bearings. Because of its compact structure, good rigidity and high bearing capacity, it is the most widely used rolling mill bearings. This type of bearing is unable to bear axial load. Therefore, it is necessary to use together with thrust bearing to withstand axial load.
Four row cylindrical roller bearings are separable bearings. Because its inner ring has no flange, the inner ring and outer ring components can be installed and disassembled separately, which is beneficial to the installation and maintenance of bearings.
It is mainly applicable to rolling mill with high rotational speed and precision. For example, wire mill, section mill, cold or hot plate mill, breakdown mill, etc. Brass solid cage or pillar welding cage is generally used.
