Mill bearing configurations

  (1) Spherical Roller Bearings 

Rolling mill bearing configuration is different, which was mainly used two self-aligning roller bearings mounted side by side on the same roll neck. This configuration type basically meet the prevailing production conditions, rolling speeds of up to 600rpm. However, as the speed increased, more prominent disadvantages: short bearing life, consumed in large quantities, low precision finished, roll neck wear serious, and large axial movement of the roll. 

(2) four cylindrical roller bearing + thrust bearing 

Cylindrical roller bearings and roll neck diameter of a tight fit, radial force, with a load capacity, high limiting speed, high precision, detachable and interchangeable inner and outer rings, easy processing, low production cost and easy installation and removal ; thrust bearing axial force, the specific structure type can be selected according to the characteristics of the rolling mill. 

Heavy at low speeds, with thrust roller bearings, with a smaller axial clearance to bear the thrust load.When the rolling speed is high, with angular contact ball bearings, not only the high speed limit, but when working axial clearance can be strictly controlled. The roll to get close axial guidance, axial load can withstand normal force. This not only has a bearing type bearing arrangement long life, high reliability, and has rolled products of high precision, easy to control, and many other advantages, the most widely used, and more for wire rod mill, lumber mill, foil mill, two support rollers cold rolling mill and hot rolling mill machines and other supporting roller. 

(3) four-row tapered roller bearings 

Tapered roller bearings can support radial forces, but also to withstand the axial force, no need to configure the thrust bearing, so the host is even more compact. Tapered roller bearings and roll neck diameter using a loose fit, installation and removal is very convenient, but sometimes due to sliding creep caused by a loose fit, so often processed with a spiral groove diameter.  This configuration type is still relatively wide applications, such as four-roll rolling mill and cold rolling mill work rolls, blooming machines, structural steel mill rolls and other occasions.
