Bearing packing and outer packing.
After the bearing is manufactured and tested, it iscleaned and treated with rust, and then put into the inner package to achievethe purpose of waterproof, moisture-proof, dustproof, shock-proof, maintainingthe quality and precision of the bearing as well as making it convenient to useand sell.
The inner packing of the bearing is divided into threecategories according to the rust prevention period:
Packaging with short rust-proof period: 3 ~ 6 months ofrust-proof period, suitable for mass delivery to the same subscriber and putinto use in a short time. According to the agreement of both parties, simplepacking is adopted for the principle of convenient use.
General rust-proof package: one year rust-proof, suitablefor general purpose bearings.
Bright long rust - proof packaging: two years rust -proof, suitable for special and precision bearings.
The inner packing material of the bearing is polyethyleneplastic tube (box), kraft paper, plain paper and wrinkle polyethylene compoundpaper, paper box, polyethylene or polyethylene plastic film, nylon fasteningbelt or plastic woven fastening belt, waterproof high strength plastic belt,jute bag, etc. All the above materials shall be qualified for the corrosionresistance test.
Principle requirements of bearing inner packing method:
Miniature bearings: each 10 ~ 15 sets of bearings arepacked into a plastic tube, each 5 ~ 10 plastic tubes are packed into a paperbox (or bag, roll).
Medium and small bearings: multiple sets of bearings arewrapped with polythene film, kraft paper or polythene composite paper. Multiplesets of bearings are loaded into a plastic barrel (box); The single bearing ispacked in polythene film bag, folded or sealed before being put into a carton.
Big bearings: wrapped in a single sheet of polythene filmor polythene composite paper, then packed in a carton; Use a polythene filmbag, a single package after folding bag mouth, and then into a carton; Singlepackage into special plastic box; Single three - layer wrapping: inner withpolyethylene film tape or composite paper tape, middle with fastening tape,outer with waterproof permeable plastic tape.
High-speed ultra-large bearing:
Single three-layer wrapping package (same as above);
Single by four wrapping: after the three wrapping layers,the outermost layer is then wrapped in a linen band.
For separable tapered roller bearings with an outerdiameter of 150mm, polyethylene film shall be padded before the inner and outercomponents, or the inner and outer components shall be separately packed. Forinterchangeable cylindrical roller bearings with an outer diameter of 150mm ormore, generally the inner and outer components can be separately packedseparately due to the vulnerability of complete package.
General materials and requirements for bearing outerpacking are as follows:
The total weight (gross weight) of each carton is no morethan 25kg, and the carton is packed with plastic straps.
The total weight of each box shall not exceed 30kg, andthe box shall be bound with blue steel straps for external use.
Golden calcium plastic corrugated box, the total weightof each box is not more than 25kg, box like to use plastic packing tape tied.
The bearing products with inner packing should be packedin plastic bags or plastic films. If there is any gap in the box, it shall befilled with dry materials such as corrugated paper pieces and paper scraps.
