Bearing packaging is divided into inner packaging and outer packaging.

After the bearing is manufactured and passed the inspection, it is cleaned and rust-proof, and then put into the inner package to achieve waterproof, moisture-proof, dust-proof, impact-proof, and maintain the quality and accuracy of the bearing. and the purpose of convenience of 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: The anti-rust period is 3 to 6 months, which is suitable for mass shipments to the same Subscribers, bearings that will be put into use in a short period of time. By agreement between the two parties, based on the principle of convenient use, simple packaging is adopted.

② General anti-rust period packaging: One-year anti-rust period, suitable for general-purpose bearings.

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

Bearing inner packing materials are polyethylene plastic tube (box), kraft paper, plain and corrugated polyethylene composite paper, carton, polyethylene or polyethylene plastic film, nylon fastening tape or plastic braided fastening Belts, waterproof high-strength plastic belts, burlap bags, etc. All the above materials need to ensure that the corrosion resistance test of the material is qualified.

Principles and requirements of the inner packing method of bearings:

①Miniature bearings: every 10 to 15 sets of bearings are put into a plastic tube, and every 5 to 10 plastic tubes are put into a carton (or in bags or rolls).

②Medium and small bearings: multiple sets of bearings are wrapped with polyethylene film, kraft paper or polyethylene composite paper inside; multiple sets of bearings are packed into a plastic cylinder (box); Packed in a vinyl bag, folded or sealed, and packed into a carton.

③Large bearing: packed in a single set of polyethylene film or polyethylene composite paper, and then put into a carton; packed in a polyethylene film bag, folded the mouth of the bag in a single set, and then put into a carton Carton; a single set into a special plastic box; a single set of three-layer wrapping packaging: polyethylene film tape or composite paper tape for the inner layer, fastening tape for the middle layer, and waterproof permeable plastic tape for the outer layer.

④Extra-large bearing:

Single set of three-layer wrapping packaging (same as above); After wrapping, wrap the outermost layer with another layer of burlap tape.

Separable tapered roller bearings with outer diameter ≥150mm should be lined with polyethylene film before the inner and outer components, or the inner and outer components should be packaged separately. Interchangeable cylindrical roller bearings with an outer diameter of ≥150mm can be packaged separately because the complete package is easy to be damaged.

The general materials and requirements for the outer packaging of the bearing are as follows:

①Double corrugated cardboard boxes, the total weight (gross weight) of each box should not exceed 25kg, and the outside of the box should be bundled with plastic packing tape;

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

③ Calcium plastic corrugated boxes, the total weight of each box does not exceed 25kg, The box loves to be bundled with plastic strapping.

When packing the bearing products with inner packaging into the box, the plastic bag or plastic film should be lined in the box first; fill up.
