6204 bearing technical parameters, 6203 bearing size parameters

6204 bearings belong to the deep groove ball bearing series.

From the perspective of use, the following points should be paid attention to to ensure that the bearing can work reliably

1. Improve lubrication quality, control the pressure, temperature and flow of oil, and strengthen oil filtration.

2. Use fuel and lubricating oil that meet the regulations.

3. Control the temperature state of the diesel generator set, and it is unfavorable to work in the case of overcooling and overheating. In cold weather, the diesel engine should be preheated before starting, and the crankshaft should be rotated by hand to make the oil enter the friction surface.

4. The surface quality and geometry of bearings and journals should be strictly guaranteed.

5. The bearing clearance should be appropriate, the generator set is too large to produce impact, too small will have poor lubrication, and the tile may be burned.

Extended information: Bearing is an important component in contemporary machinery and equipment. Its main function is to support the rotating body of the machine and reduce the coefficient of friction during its movement

coefficient) and ensure its rotation accuracy.

Bearing role. In terms of its function, it should be a support, that is, it is literally used to support the shaft, but this is only part of its role, and the essence of the support is to be able to bear radial loads. It can also be understood that it is used to fix the shaft.

Bearing fast and easy to optimize the automatic selection is included. It is to fix the shaft so that it can only rotate, and control its axial and radial movement.

If the motor does not have bearings, it will not work at all. Because the shaft can move in any direction, and the motor requires the shaft to only rotate when working. Theoretically, it is not possible to achieve the effect of transmission, and not only that, but the bearing also affects the transmission, and in order to reduce this effect, it is necessary to achieve good lubrication on the bearing of the high-speed shaft.

Some bearings themselves have been lubricated, called pre-lubricated bearings, and most of the bearings must have lubricating oil, responsible for high-speed operation, due to friction will not only increase energy consumption, more terrible is that it is easy to damage the bearing. The argument that sliding friction is converted into rolling friction is one-sided, because there is something called plain bearing.

The role of the bearing

Bearing is an important component in contemporary mechanical equipment, its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement.

And ensure its rotation accuracy. Under a certain load, the number of revolutions or hours experienced by the bearing before pitting corrosion occurs is called the bearing life, which is the standard for determining the bearing life, and the bearing life is linked to reliability.

In order to compare the bearing capacity of the bearing against pitting corrosion, it is specified that when the rated life of the bearing is one million rpm, the maximum load that can be borne is the basic rated dynamic load, which is expressed as C. That is, under the action of the rated dynamic load c, the reliability of the bearing working for one million revolutions without pitting corrosion failure is 90%, and the larger the c, the higher the bearing capacity.
