The contact type of the cylindrical roller bearing roller and the raceway is line contact. The bearing capacity and rigidity of cylindrical roller thrust bearing are higher than that of the angular contact ball bearing (including the multi-coupling bearings), which belongs to the point contact, but the allowable rotation speed of the cylindrical roller bearing is lower. Most designs are separable and can be easily assembled and disassembled. Therefore, cylindrical roller bearings are often used in medium and large machine tools and machining centers where the load is large and the rigidity is high, while the rotational speed is relatively low.

ZYS can design and offer full range of single row cylindrical roller bearings and double row cylindrical roller bearings. In order to meet the requirements of high speed, high rigidity and long life, ZYS has developed high-speed hybrid ceramic cylindrical roller bearing, that is, the inner and outer ring of the bearing is made of high-quality bearing steel material, and the cylindrical roller is made of silicon nitride ceramic. Compared with standard steel cylindrical roller bearings of the same structure and size, it has the advantages of high speed performance, high rigidity, low friction, long life and high reliability, which can significantly improve the production efficiency and extend the life of machine.
