Beschreibung
Zusammenfassung:	The utility model discloses a rolling mill. A thrust bearing is additionally arranged outside a rotating arm of a sleeve removing device for the rolling mill, and is pressed by a pressing device. Axial force is applied to the rotating arm through the thrust bearing and simultaneously radial friction force is provided, so that uneven stress of the rotating arm is eliminated and the abrasion of a sliding bearing caused by unilateral friction generated in a rotating process can be avoided.
