Four Row Tapered Roller Bearings

Four row tapered roller bearings can endure both radial force and axial force without thrust bearings to make the main machine more compact. The inner diameter and the roll neck of four row tapered roller bearings work together with loose fit-up for convenient installation and dismounting. However sometimes the loose fit-up will slip. So the inner diameter will be made with screw oil tank.

At present, this specification model is still widerly applied in the working rolls of the four row hot rolling mill and cold rolling mill, bloomer and beam rolling mill.    

Generally speaking, the rolling mill stands will have 2 rolls, 3 rolls, 4 rolls, or a set of multiple rolls mounted onto the stands.  The loads on the rolls will transfer to the roll neck bearings and their housings during the rolling of steels. The roll neck bearings are to meet the basic need of the smooth rolling of steel products. They will differ from sizes, carrying capacities and other aspects, due to different requirements and working conditions. Therefore, they will have different configurations and speeds of rolling.

The bearings are designed to withstand high loads, impacts, varying speeds and high temperature. They also need to work with metal particles, dirt, and water. Therefore, the bearings should be made with good material and technique to endure the toughest working conditions. Roll neck bearings with high quality will help steel mills reduce a lot for reducing power consumption, downtime, and improving rolling conditions.

With best bearing material choosing, and strict control on processing, ESG Bearing is able to meet most modern steel mills’ high requirements. ESG Bearing is also the only 1 factory bearing manufacturers having 100% flaw detection on the bearings. Thus the bearing quality will be assured.
