Four row cylindrical roller bearings + Thrust Bearings

Cylindrical roller bearings inner diameter works together with roll neck to endure radial force. It has the advantages of heavy load, high rotation speed limit, high precision,inner and outer rings seperability and replacability, easy procession, lower production cost and convenient mounting and dismounting. The thrust bearings endure axial force. The detailed structure type can be chosen based on rolling mill feature.

When the heavy load speed is slow, the cylindrical roller bearings work with thrust bearings to endure thrust load with smaller axial clearance. When the rolling speed is higher, it works with angular contact ball bearings with higher rotation speed limit and with strick control of axial clearance to make the roller work with close axial guide and endure general axial load force.

This bearing specification type has the advantage of longer bearing life, reliability, high presion of the rolling products and easy control. So they are applicant widely in wire steel rolling mill, plate steel rolling mill,frame rolling mill, double-support roll of cold rolling mill and hot rolling mill.
