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.
