The invention discloses a high-pressure spray aqueous solution degreasing system applied to a bearing cleaning line. The high-pressure spray aqueous solution degreasing system applied to the bearing cleaning line comprises a cleaning tank, spraying pipes installed on two lateral faces of the cleaning tank, nozzles distributed on the spraying pipes and a rotary table arranged in the middle of the cleaning tank. A liquid storage tank is arranged below the cleaning tank and is internally provided with a heating pipe. The bottom of the liquid storage tank is provided with a liquid conveying pipeline communicated to the spraying pipes. A multi-stage centrifugal pump is arranged on the liquid conveying pipeline. The nozzles distributed on the spraying pipes are used for spraying and cleaning a bearing part, a good cleaning effect is achieved, and especially, as the rotary table is provided, when the bearing part is arranged on the rotary table, the bearing part can be comprehensively cleaned. The liquid storage tank can recycle aqueous solutions, recycled aqueous solutions are conveyed to the nozzles again for spraying use, the aqueous solutions are effectively recycled, and the cost is reduced.
