Installation And Maintenance Procedures For Thin Wall Deep Groove Ball Bearings

Thin Wall Deep Groove Ball Bearings

1、 The bearing must be installed and removed carefully

Different kinds and sizes of thin-walled deep groove ball bearings have different installation methods and tools, including mechanical or hydraulic ones. Deep Groove Ball Bearings Here are some general basic installation methods and precautions.

Do not install the ball with force, which will lead to local overload of the ball and Deep Groove Ball Bearings contact surface and premature failure of the bearing.

Second, do not hit the surface of the bearing with hard tools, such as hammer and screwdriver, Deep Groove Ball Bearings which will break or embrittle the outer ring of the bearing.

2、Thin Wall Deep Groove Ball Bearings cleaning

A clean service environment is very important for bearings.

The surface roughness accuracy of the rotating surface of the thin-walled deep groove ball bearing ring and the rolling element is about 1 / 10 μ m.

If such a smooth ball surface is polluted, its influence is Deep

Thin Wall Deep Groove Ball Bearings very serious. The lubricating layer between rolling surfaces is usually 0.2 ~ 1 μ m.

Granular impurities larger than the lubricant particle size will be over rolled by the rolling elements and produce local pressure in the self-aligning roller bearing steel, Deep Groove Ball Bearings which will eventually lead to permanent material fatigue.

In addition to this, the size of dust particles in the external environment can reach 10 μ m. It will also damage the self-aligning roller bearing.

Because of this, how important a clean and tidy working environment is for bearings.

3、 Process inspection of bearing

During use, the working temperature of the bearing is sensed by heat drying. If the temperature exceeds the specified limit, it will automatically alarm to prevent the occurrence of combustion shaft. High temperature often indicates that the bearing is in an abnormal condition. High temperatures are also harmful to bearing lubricants. Sometimes the overheating of thin-walled deep groove ball bearings can be attributed to the lubricant of the bearings.

If the temperature of the bearing exceeds 125 ℃ for a long time, the service life of the bearing can be reduced.

Deep Groove Ball Bearings The causes of high-temperature bearing

Thin Wall Deep Groove Ball Bearings include:

the bearing may have insufficient lubrication, unqualified lubricant, impurities in it, insufficient clearance in the bearing when the load is too large, friction caused by oil seal, etc.

Centripetal thrust ball bearing is a precision part,so it is required to be quite cautious in use, that is, it uses high-performance bearing.

If it is not used properly, it can not achieve the expected performance effect, Deep Groove Ball Bearings and it is easy to damage the bearing.

Therefore, pay attention to the following matters when using bearings:

However, under some special operating conditions, the centripetal thrust ball bearing can obtain a longer life than the traditional calculation, especially under light load.

Deep Groove Ball Bearings These special operating conditions are the surface damage that may be caused when the rolling surface (track and rolling parts) is effectively separated and limited by a lubricating oil film.

In fact, under ideal conditions, the so-called permanent bearing life is possible.

Deep Groove Ball Bearings
Grease lubrication includes the sealing method of filling grease in the sealed bearing in advance,

and the filling grease supply method of filling an appropriate amount of grease in the shell and replenishing or replacing it at regular intervals. In addition, the centralized grease supply mode with pipes connected to each lubrication point is also adopted for the machinery with multiple centripetal thrust ball bearings that need lubrication.

Grease lubrication can be filled with grease for a long time without supplement, and the structure of its sealing device is simple, so it is widely used. Oil lubrication is relatively simple. The installation and disassembly method of centripetal thrust ball bearing shall be determined according to the structure, size and matching nature with bearing components. The pressure of installation and disassembly shall be directly added to the end face of the tight fitting retaining ring,

and the pressure cannot be transmitted through the rolling element, because it will cause indentation on the working surface of the bearing, affect the normal operation of the bearing, and even damage the bearing. The cage, sealing ring, dust cover and other parts of the bearing are easy to deform, and the pressure for installing or removing the bearing cannot be added to these parts.
