The invention provides a moving block sealing end cover for a finishing mill, and relates to the technical field of steel sheet finishing milling equipment. The moving block sealing end cover for thefinishing mill comprises a through cover, an anti-collision ring, a first guide belt and an oil seal, wherein a discharging port is formed in the outer end surface of the anti-collision ring and is radially connected along the anti-collision ring; and the oil seal is positioned between the guide belt and the anti-collision ring. According to the moving block sealing end cover for the finishing mill, the first guide belt arranged on the through cover is capable of effectively preventing abrasion of a cylinder barrel and a piston rod of a bending roller hydraulic cylinder; a self-positioning head at the end part of the piston rod of the bending roller hydraulic cylinder can be protected through the anti-collision ring, and thus the service life of the piston rod can be prolonged; the discharging port in the anti-col
