Large bearing: Pack it in a single set of polyethylene film or polyethylene composite paper, and then put it into a carton; use a polyethylene film bag, pack the single set of folding bag openings, and then put it into a carton; put the single set into a special plastic box; Three-layer wrap-around 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.
Extra large bearings: Single set of three-layer wrapping packaging (same as above); single-time four-layer wrapping packaging: After the above three-layer wrapping, the outermost layer is wrapped with a layer of linen tape.
For separable tapered roller bearings with outer diameter ≥ 150mm, the inner and outer components should be lined with polyethylene film before packaging, or the inner and outer components should be packaged separately. For interchangeable cylindrical roller bearings with an outer diameter of ≥150mm, because the complete package is easy to be damaged, the inner and outer components can be packaged separately.
The general materials and requirements of bearing outer packaging are as follows: Double corrugated paper box, the total weight (gross weight) of each box does not exceed 25kg, and the outside of the box is tied with plastic strapping; Nail board box (wooden box), the total weight of each box does not exceed 30kg, and the outside of the box is tied with blue steel tape; Calcium Plastic corrugated boxes, the total weight of each box does not exceed 25kg, the boxes are bound with plastic straps.
When packing the bearing products with inner packaging into the box, the box should be lined with plastic bags or plastic film; if there is any space in the box, it should be filled with dry materials such as corrugated paper blocks and paper scraps.
