Bearing packaging is divided into inner packaging and outer packaging.

After the bearing is manufactured and passed the inspection, it will be cleaned and anti-rust treated, and then put into the inner packaging to achieve the purpose of waterproof, moisture-proof, dust-proof, shock-proof, maintain the quality and accuracy of the bearing, and facilitate the use and sale. .

The inner packaging of the bearing is divided into three categories according to the anti-rust period:

①Short anti-rust period packaging: 3-6 months anti-rust period, suitable for bearings that are shipped to the same subscriber in large quantities and put into use in a short period of time. The two parties have agreed to use simple packaging based on the principle of ease of use.

②Packaging for general anti-rust period: one year of anti-rust period, suitable for general-purpose bearings.

③Long anti-rust period packaging: two years anti-rust period, suitable for special and precision bearings.

The inner packaging materials of the bearing include polyethylene plastic tube (box), kraft paper, plain and wrinkled polyethylene composite paper, paper box, polyethylene or polyethylene plastic film, nylon fastening tape or plastic woven fastening tape, waterproof high-strength plastic tape , Burlap bags, etc. All of the above materials need to ensure that the corrosion resistance test of the material is qualified.

The general materials and requirements for the outer packaging of cylindrical roller bearings are as follows:

①Double corrugated boxes, the total weight (gross weight) of each box does not exceed 25kg, and the outside of the box is bound with plastic packing tape;

②Nail board box (wooden box), the total weight of each box does not exceed 30kg, and the outside of the box is bound with blue steel tape;

③Calcium-plastic corrugated boxes, the total weight of each box does not exceed 25kg, the boxes are bound with plastic straps.

When packing bearing products with inner packaging into the box, plastic bags or plastic films should be lined in the box first; if there are gaps in the box, it should be filled with dry materials such as corrugated paper blocks and paper scraps.
