Dustproof anti-deformation retainer of linear bearing

The utility model relates to the technical field of linear bearings, and discloses a linear bearing dustproof anti-deformation retainer which comprises a shell, a first fixing plate is fixedly installed at the upper end of the shell, a dustproof pad is fixedly installed on the inner side of the shell, and an installation block is fixedly installed on the inner side of the shell. During installation, the dustproof and deformation-resistant retainer for the linear bearing is adaptive to rotating shafts with different diameters, dustproof pads at the upper end and the lower end of a shell of the retainer are attached to the rotating shafts, dust is effectively prevented from entering the retainer, stress generated by bearing breakage can be eliminated when the rotating shafts rotate through cooperation of springs and damping columns, and the service life of the retainer is prolonged. The mounting plate blocks parts inside, damage to personnel and equipment caused by splashing of metal fragments when the rotating
