Thin-wall waterproof bearing

The utility model provides a thin-wall waterproof bearing and relates to the technical field of waterproof bearings. The problems that an existing thin-wall waterproof bearing is poor in reinforcing effect, meanwhile, continuous attaching sealing cannot be achieved, the oil sealing effect is poor, and local corrosion of the bearing is caused by extremely easy leakage are solved. Comprising a bearing body. The bearing main body piece is fixedly connected with a reinforcing sealing piece; two fitting holding parts are sleeved in the bearing main body piece, and the two fitting holding parts are connected in a magnetic attraction manner; the two attaching maintaining parts are fixedly connected with dustproof protection pieces correspondingly. By adopting the bearing main body piece matched with the reinforcing sealing piece, the bearing can be reinforced in an auxiliary manner, the overall structural strength of the thin-wall bearing can be improved, meanwhile, the sealing effect can be reinforced in an auxilia
