In the detection of main observation bearing the rivet when head have skewed, relaxation welding position is correct. Maintains a good or bad of welding. Welding point is too small, a welding not firm, or welding excessive cause card problems such as the ball. Is in the process of testing FAG bearing particular attention place. There is also some problems need to be aware of.

Here to share many years of work experience of the bearing local detection. First of all in the environment of the inspection should be bearing FAG in light of the environment, had better be astigmatism, in order to better to FAG bearing external observation, look at the surface and no crack and other different. Such as machinery in the process of cloud wear, Nick, pressure touch, will lead to FAG bearing device migration, lead to bad position device, cause flat load and stress concentration, the modelling of the bearing accuracy and use FAG service life of reduced.

1, FAG bearing maintenance, repair, and the processing of abnormal
For as long as possible with good performance of the original state maintain bearing, shall be the maintenance, the maintenance, in order to prevent accident cure, ensure reliability of operation, improve productive and economy. Maintenance of the conditions of the mechanical operation best corresponding operation standard, on a regular basis. Includes, surveillance operation state, add or replace lubricant, regular remove examination.

As to the working maintenance matters, have bearing rotation sound and vibration, temperature, lubricants state, and so on.

2, FAG damage and countermeasures of the bearing
Generally, if right use of bearing, can use to reach fatigue life so far. But there will be unexpected prematurely damage, is not able to bear or endure in use. This early damage, and fatigue life relatively, to be called a fault or accident quality use limit. Many due to the installation and use of lubrication, do not pay attention to and from external invading foreign body, for shaft, the effect of the shell hot enough, etc.

The damage status about FAG bearing, such as: roller bearing rings raised edge card injury, as a cause may be considered, lubricant lack, not suitable for, for the defects of soot structure, foreign body invasion, bearing installation error, shaft buckling is too big, also can have these reasons superposition.

Therefore, only survey FAG bearing damage, it was hard to know that the real cause of the damage. But, if know the use of machinery, bearing conditions of use, bearing the structure, around about accidents of the situation before and after, combining bearing damage status and several reasons investigation, it can avoid the same accident happen again.
Relevant FAG bearing use of the note as follows:

Keep the bearing and FAG turnover clean

Even the small dust eyes see, also can give a FAG has a bad influence on bearing. So, to keep clean around, make dust from invading FAG bearing.
Careful to use

In use give FAG bearing strong impact, will produce the scars and impress, become the cause of the accident. Severe cases, will crack, fracture, so must pay attention to.

Using the appropriate FAG operating tools

Avoid to existing workers bearing with instead of, must use appropriate tools. We often emphasize the importance of tools, because there are too many customers in the installation of use the wrong tool caused FAG bearing damage.

To pay attention to FAG bearing the corrosion
Operation FAG bearing, hands sweat will be the cause of rust. To pay attention to use clean hand operation, better try to take the gloves.
