Bearing in manufacturing finished and after passing inspection, namely cleaning and anti-rust treatment, then placed the package in order to waterproof, moisture, dust, shock, maintain quality and precision bearings as well as ease of use and sale purposes . Packaging bearing inner and outer packaging can be divided into two kinds.
Bearing packing press rust into three categories:
① short rust Packaging: Rust of 3 to 6 months, for high-volume shipments to the same subscriber, will be put into use in the short term bearing. By mutual agreement, in order to facilitate the use of the principle, the use of simple packaging.
② general rust Packaging: Rust period of one year, for bearing general purpose.
③ long rust-proof packaging: rust period of two years, applies to private and precision bearings.
Packaging material bearing polyethylene plastic tube (box), kraft paper, polyethylene composite plain and wrinkled paper, cartons, polyethylene or polyethylene plastic film, plastic woven nylon fastening tape or fastening tape, waterproof high-strength plastic tape , sacks and the like. These materials are required to ensure corrosion-resistant material capable of passing the test.
Principles of bearing packaging method requires:
① miniature bearings: every 10 to 15 sets of bearings packed into a plastic tube, every 5 to 10 plastic tube put into a box (or bag, wrapping).
② medium and small bearings:
Volume package were several sets of bearings with polyethylene film, polyethylene composite paper kraft paper or external;
Sets bearing into a plastic tube (box);
Single sets of bearings with polyethylene film bag, seal the bag and then into the fold or a tray.
③ large bearing:
With polyethylene film or polyethylene composite paper packaging single set, and then loaded into a carton;
With polyethylene film bags, packaging folding pocket after a single set, and then into a carton;
Single suit into a special plastic box;
A single set of three wrapped package: inner layer polyethylene film with or composite tape, middle fastening band, the outer layer of waterproof plastic tape penetration.
④ large bearings:
A single set of three wrapped packages (ibid.);
Take four single wrapping Packing: wrapped package in the above three, the outermost layer and then wrapped with linen.
≥150mm separable outer diameter tapered roller bearings in the front of packaging, should liner polyethylene film before outside the component, or the inner and outer components separately packaged.
≥150mm interchangeable outer diameter cylindrical roller bearings, because packaging kit easily knock injury, general internal and external components can be packaged separately.
Bearing packaging materials and general requirements are as follows:
① double corrugated boxes, each box Total weight (gross weight) does not exceed 25kg, box strapping external plastic packaging;
② nail crate (wooden), each containing a total weight does not exceed 30kg, external box blue steel strapping;
③ Gaisu corrugated boxes, each containing a total weight does not exceed 25kg, love to use plastic packing box strapping.
