The bearing package is divided into inner and outer packaging.
After the bearing is manufactured and tested, it is cleaned and rust-proofed, and then placed in the inner packaging to achieve waterproof, moisture-proof, dust-proof, shock-proof, maintenance bearing quality and precision, and convenient use and sales. .
The inner packaging of the bearing is divided into three categories according to the anti-rust period:
1 Short rust-proof period Packing: The rust-proof period is 3 to 6 months. It is suitable for bearings that are shipped to the same subscriber in large quantities and put into use in a short period of time. According to the agreement between the two parties, the principle of convenient use is adopted, and simple packaging is adopted.
2 general anti-rust period packaging: anti-rust period of one year, suitable for general purpose bearings.
3 long anti-rust period packaging: anti-rust period of two years, suitable for special and precision bearings.
The inner packaging material of the bearing is polyethylene plastic tube (box), kraft paper, plain and wrinkle polyethylene composite paper, carton, polyethylene or polyethylene plastic film, nylon fastening tape or plastic fastening tape, waterproof high-strength plastic tape , linen bags, etc. All of the above materials are required to ensure that the corrosion resistance of the material is tested.
The principle requirements for the inner packaging method:
1 Miniature bearing: Every 10~15 sets of bearings are loaded into a plastic cylinder, and every 5~10 plastic cylinders are loaded into a paper box (or bag, roll).
2 medium and small bearings:
——Multi-bearing bearing is wrapped with polyethylene film, external kraft paper or polyethylene composite paper;
- multiple sets of bearings are loaded into a plastic cylinder (box);
——The single set of bearings is packed in polyethylene film bags, folded or sealed and then loaded into a carton.
3 large bearings:
——Packed in a single film of polyethylene film or polyethylene composite paper, and then loaded into a carton;
——With a polyethylene film bag, the single bag is folded into the bag and then loaded into a carton;
——Single into a special plastic box;
——Single set of three-layer wrap packaging: polyethylene film tape or composite paper tape for the inner layer, fastening tape for the middle layer, and waterproof and permeable plastic tape for the outer layer.
