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.

The following pesticides cannot be mixed:
Bordeaux mixture and stone sulphur mixture cannot be mixed. Because the two pesticides will chemically change after mixing, the formation of copper polysulfide will not only reduce the efficacy, but also cause phytotoxicity. When using these two pesticides in succession, it is also necessary to wait for a certain period of time. First use stone sulphur mixture, it is necessary to spray Bordeaux mixture after 20 to 25 days; first spray with erg multi-liquid, it takes 25 to 30 days to use stone sulphur mixture.
Bordeaux mixture and stone sulphur mixture and most insecticides, such as phoxim, trithiaphos, phosphonium, dichlorvos, dicofol, ketone, carbaryl, etc. are not mixed, after mixing, the agent will decompose and fail. Microbial insecticides, such as Beauveria bassiana and Penicillium, cannot be mixed with microbial fungicides such as Jinggangmycin and Chunremycin, otherwise the microorganisms will be killed and the efficacy will be reduced.
Oil emulsions and soaps can not be mixed with most insecticides and fungicides. When mixed, it will cause decomposition or precipitation of the drug to reduce the efficacy. The combination of organophosphorus pesticides and deltamethrin can increase the insecticidal effect, but it can also increase the toxicity to humans.
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 main pesticides for controlling fruit tree seedling diseases are: Bordeaux mixture, daisen zinc, thiophanate, carbendazim, bacteriostatic, ethylphosphorus, chlorhexidine, chlorpyrifos, etc. These pesticides are called fungicides and their main role is to inhibit Or kill all kinds of pathogens; the main pesticides for controlling fruit tree seedling pests are: killing pine, phoxim, omethoate, dicofol, ketone, acesulfame, deltamethrin, chlorpyrifos and so on. This kind of pesticide is called insecticide, and its main function is to kill pests through different poisoning methods such as stomach poisoning, contact killing, systemic absorption and fumigation. Another pesticide, such as stone sulfur mixture, is both disease prevention and pest control.
