The inner packaging of bearings is divided into three categories according to the anti-rust period: ① Short anti-rust period packaging: The anti-rust period is 3 to 6 months, suitable for bearings shipped in large quantities to the same subscriber and put into use in a short period of time. After the agreement of both parties, simple packaging is adopted based on the principle of convenience. ② General anti-rust period packaging: The anti-rust period is one year, suitable for general-purpose bearings. ③ Long anti-rust period packaging: The anti-rust period is two years, suitable for special and precision bearings. The outer packaging materials of bearings include polyethylene plastic tubes (boxes), kraft paper, plain and wrinkled polyethylene composite paper, paper boxes, polyethylene or polyethylene plastic films, nylon fastening belts or plastic woven fastening belts, waterproof high-strength plastic belts, burlap bags, etc. The principle requirement of the inner packaging method of bearings is to wrap the bearings with polyethylene film.
