The invention discloses a pressurized deformation type bearing outer ring-lining adhesion method. The method comprises the following steps: performing surface treatment to the inner surface of a bearing outer ring and the adhesion surface of a lining, and coating an adhesive on the treated surfaces; arranging a pressurization mold according to the geometric shape of the inner surface of the bearing outer ring, and attaching a non-adhesion surface of the lining onto the pressurization mold; connecting a pressurization pipeline, filling the pressurization mold with hydraulic oil or an inert gas, to cause the deformation of the pressurization mold and further enable the adhesion surface of the lining to be entirely attached to the inner surface of the bearing outer ring and applying even pressure to the lining; placing an adhesion device and a bearing outer ring assembly into a heating furnace for performing curing adhesion; and performing pressure relief and disassembling on the pressurization mold after the curing adhesion is completed. The pressurization mold used in the pressurized deformation type bearing outer ring-lining adhesion method is simple in structure, and can be designed according to the type and dimension of a bearing; and constant and even pressure can be applied to the lining during curing adhesion, and the adhesion strength is high.
