Since the beginning of the bearing and outer packaging.

Bearing in the manufacture of finished and after passing inspection, cleaning and rust treatment that is then placed inside the packaging in order to achieve waterproof, moisture-proof, dust-proof, anti-shock, maintaining the quality and accuracy of the bearing and the purpose of ease of use and sale .

Bearing inner packing by anti-rust period is divided into three categories:

① Short rust Packing: rust of 3 to 6 months, suitable for large volume shipments to the same subscriber, the short term will be put into use bearings. By mutual agreement, in order to facilitate the use of the principle, the use of simple packaging.

② general rust Packing: anti-rust period of one year, for general purpose bearings.

③ long rust Packing: anti-rust period of two years for special and precision bearings.

Bearing polyethylene plastic tube packaging materials (boxes), kraft paper, plain paper and wrinkles polyethylene, paper, polyethylene or polyethylene plastic film, plastic woven nylon fastening tape or grip tape, waterproof high-strength plastic tape , hessian bags and so on. These materials are required to ensure that the corrosion resistance of materials passing the test.

Bearing inner packaging method in principle requirements:

① miniature bearings: every 10 to 15 sets of bearings into a plastic tube, every 5 to 10 plastic tube into a box (or bag, wrapping).

② medium and small bearings:

Several sets of bearings with polyethylene film, topical kraft paper or polyethylene composite paper bag for;

Multiple sets of bearing into a plastic tube (box);

A single set of bearings with polyethylene film bag, folded, or seal the bag and then into a carton.

③ large bearings:

With polyethylene film or polyethylene single set of composite paper packaging, and then into a carton;

With polyethylene film bag, a single set of packaging folding bag, and then into a carton;

Single package into a special plastic boxes;

Single set of three wrapped Packing: inner layer of polyethylene film tape or composite tape, middle fastening belt, the outer belt with waterproof plastic penetration.

④ large bearings:

Single set of three-wrapped package (ibid.);

Take four single-wrapped package: In the three-wrapped packaging, the outermost layer and then wrapped with linen.

Outside diameter ≥ 150mm detachable type tapered roller bearings, before packing the inner and outer components should be preceded liner polyethylene film, or the inner and outer components packaged separately.

Outside diameter ≥ 150mm interchangeable cylindrical roller bearings, complete packing easy knock injury due to general internal and external components can be packaged separately.

General Bearing packaging materials and requirements are as follows:

① double corrugated boxes, each containing a total weight (gross weight) does not exceed 25kg, external plastic packing box strapping;

② nail crate (wooden box), each containing a total weight not exceeding 30kg, Box topical blue strip strapping;

③ Gaisu corrugated boxes, each containing a total weight not exceeding 25kg, love to use plastic packing box strapping.

The bearing products with inner packing into the box, should be in the box liner bags or plastic film; inside any gaps, needed corrugated blocks, paper and other dry material filled.

Bearing parts

(A) General bearing parts

1 bearing parts

One of the parts composed of rolled rings, but does not include all the accessories.

2 bearing rings

With one or several raceway bearing to the heart of the annular parts.

3. Bearing Washers

With one or several thrust bearing raceway ring parts.

4 flat ring

A detachable substantially flat washer, with its inner or outer part as radial cylindrical roller bearing outer or inner ring of a wall.

5. Thrust collar (detachable)

A separable with "L" shaped cross-section ring, with the outer part of a radial cylindrical roller bearing inner ring of a wall.

6 in the ring

Having two or more rows of rollers of a roller bearing detachable inner circle, used to isolate two rollers and guide rollers.

7 snap ring

Having a constant cross-section single-port ring, mounted in a ring ditch, a roller bearing in the housing or shaft axial position.

8 lock ring

Having a constant cross-section single-port ring, mounted in the annular ring ditch as rollers or cage will remain in the bearing.

9 spacer

Is annular parts, for two bearing rings or bearing washers or between two halves or between the bearing rings bearing washer between the two halves so that they are required to maintain between the axial distance.

10. Seal

Formed by one or several parts of the ring cap fixed to the bearing and a ferrule or the gasket ring or gasket in contact with another or to form a narrow gap labyrinth, prevent oil leakage and foreign matter.

11 Cover

Is a ring cover, usually a thin metal plate stamping, a ring fixed to the bearing or a washer and extending towards the other ring or gasket, cover the space inside the bearing, but not in contact with another ring or gasket .

12 retainer

Attached to the inner ring on the shaft or a part, using centrifugal force to enhance the bearing capacity to prevent intrusion of foreign objects.

13 rolling elements

In between the rolling ball raceway or rollers.

14 Cage

Partially wrapping the whole or some of the rolling elements and the bearing parts for movement therewith, to isolate the rolling elements and the rolling elements and also often lead to keep it within the bearing.
