Thin wall ball bearings are simple in structure and easy to use. Mainly used to bear radial load, but when the radial clearance of the bearing is increased, it has a certain performance of Angular Contact Ball Bearing and can bear combined radial and axial load.
Thin wall ball bearings have a bearing inner diameter and outer diameter ratio less than a specified value. The ratio of bearing outer diameter to bearing inner diameter is 1.25 or less. It is called thin wall ball bearings, which means that the outer diameter-inner diameter value of the bearing is very small and the bearing wall is very thin.

(8) Add "sale packaging" /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
In recent years; many bearing factories are competitive in the market for progressive products; in addition to shipping packaging; also selling packaging. The packaging container is beautiful in appearance; ingeniously made; easy to carry, with better decorative depiction; to promote and add Product added value. Some of the specific requirements are in accordance with the rules of GB/T 12123 "selling package depiction procedures".
(9) Adding the demand for “other new materials†Although the outer packaging materials of China's bearing occupations are still mainly wooden boxes and cartons; however, these years; calcium plastic corrugated boxes, metal containers and plastic packaging (heat shrinkable packaging film) are also used. However, the new information must be verified by experiments; the strength of the package should be ensured and meet the storage and handling requirements.
2 JB/T 4036-2004
This specification is a revision of JB/T 4036 1993 "Trays for Rolling Bearings and Large Wooden Boxes". Since the implementation of the 1993 version of the specification, it has promoted the completion of containerized transportation of bearing products; this specification has also become the bearing of each bearing production company (factory). Guiding specifications for storage and transportation packaging.
In addition to the specification and corrections in accordance with the requirements of GB/T 1.1-2000, the specification also made the following amendments:
(1) Amend some terms according to the new terminology specification GB/T 3716-2000 "Tray Terminology"; change "double import flat tray" and "four import flat tray" to "two-way flat fork" and "four-way" Fork flat tray".
(2) Removal of the external dimensions of the tray and the cover plate. Now there is a specification for the external scale of the special regulation tray GB/T 2934 1996 "The first scale and common service of the intermodal universal flat pallet"; the external scale of the pallet can be directly selected from the specification The external scale; other non-standard scales can also be selected, the scale of the cover disc can be based on the bearing area of ​​the pallet package; it is determined by the application unit of the pallet.
(3) Improving the layout of the four-way fork flat tray The four-way fork flat tray in the original specification can be used for four-way forks; however, the vertical and horizontal decking of the non-loading surface is connected by the wrong seam; The weight of the original is thicker; the waste of the original data also increases the difficulty of processing. Many foreign customers; especially in Europe and the United States; they all need storage and transportation bearings to choose the tray layout of Figure 3.
(4) The pallet data has been abolished by magnesite; the production process of plastic magnesite crucible is complicated; the price is high; the cabinet is self-contained; the movement is inconvenient; the kind of packaging does not meet the requirements of green environmental protection; It is disposed of; it is a packaging material for dry screening.
Plastic is a new type of packaging material; the application of vision is very broad; it can replace wood; to deal with China's limited timber resource problems.
(5) Adding a polyethylene shrink film or a stretch film to wrap the package. Previously, the package and the cover plate are placed on the tray; after the steel strip is strapped; to ensure that the package is rainproof and dustproof; The cover covers the tray package. This traditional packaging method is simpler and easier to implement; but the package is not beautiful; the plastic cover can only play the role of rain and dust. Since 1998, the major bearing factories are now A continuous packaging method has been adopted: using a wraparound machine; wrapping the polyethylene stretch film on the tray package. The layout of the wraparound machine is simple; it can be purchased cheaply; the polyethylene stretch film can be selected according to requirements. The same thickness; the number of layers around can also be selected by yourself. This wrapping method not only protects the plastic cover from rain and dust, but also makes the tray package a whole; the package is fixed on the tray; Fixed effect.
(6) Remove the triangular raft from the four corners of the large wooden box in the large wooden box to strengthen the wooden box; it makes the wooden box stronger. But this not only adds the amount of wood for the wooden box; The cost of the triangle raft in the wooden box has a certain weight and space; in particular, the impact on the number of cartons; the storage and transportation costs to add. Remove the triangular raft; other aspects of normal processing according to demand; Ensure the strength of the wooden box.

The next part: The reason for the oscillation of the bearing and its damping method
When the speed is high and thrust ball bearings are not suitable, thin wall ball bearings can also be used to bear pure axial loads. Compared with other types of bearings of the same size, this type of bearing has a small friction coefficient and a high limit speed. But it is not impact resistant and not suitable for heavy loads.
The precision required by thin wall ball bearings is very high, because the wall is very thin, so the weight it can carry is also very low, and the impact resistance is very poor, so this must be selected according to the use environment!
Characteristics
The specific use of thin wall ball bearings:
Model airplanes, remote control cars, machine tools, motors, water pumps, agricultural machinery, textile machinery, laser printers, instruments, measuring instruments, electronic accessories, motors, motors, etc.
