Maintenance And Damage Countermeasures Of Nsk Bearing

Damage Countermeasures 

During the inspection, mainly Countermeasures observe whether the rivet head of the bearing is skewed, loose and whether the welding position is correct. The welding of cage is good or bad.

Whether the welding point is too small, the welding is not firm, or the ball clamping caused by Countermeasures excessive welding. These are the places that need special attention in the process of testing NSK Bearings. There are also some problems that need attention.

Now let’s share with you the local inspection of bearing in many years of work experience. First of all, in the environment, the inspection of NSK bearing should be carried out in the environment with light, which is astigmatism, so as to better observe the outside of NSK bearing and see that there are no cracks and other abnormalities on its surface.

For example, the wear, scratch and collision in the process of Countermeasures mechanical cloud will lead to the deviation of NSK bearing device, resulting in poor position of the device, flat load and stress concentration, and reduce the accuracy and service life of modeling NSK bearing.

1. NSK bearing maintenance, overhaul and abnormal handling

In order to maintain the original performance of the bearing in good condition for as long as possible, it is necessary to Countermeasures maintain and repair in order to prevent accidents, ensure the reliability of operation and improve productivity and economy.

Maintain the operation standard of corresponding mechanical Countermeasures operation conditions and carry out it regularly. The contents include monitoring the operation status, replenishing or changing the lubricant, and regular disassembly inspection.

As maintenance items in operation, there are bearing rotation sound, vibration, temperature, lubricant state, etc.

Maintenance And Damage Countermeasures Of Nsk Bearing

2. Damage and Countermeasures of NSK bearing

Generally, if the bearing is used correctly, it can be used until the fatigue life is reached. However, there will be accidental and Countermeasures premature damage, which is not resistant to use. This early damage, as opposed to fatigue life,

limits the use of quality known as failure or accident. Most of them are caused by careless Countermeasures installation, use and lubrication, foreign matters invading from the outside, and insufficient research on the thermal effects of shafts and shells.

As for the damage state of NSK bearing, for example, the clamping damage of the ring retaining edge of roller bearing can be considered as the reason.

These reasons can also coincide with insufficient lubricant, unsuitable, defects of oil supply and drainage structure, intrusion of foreign matters, bearing installation error and excessive deflection of shaft.

Therefore, it is difficult to know the real cause of the damage only by Countermeasures investigating the damage of NSK bearing.

However, if we know the use machinery, service conditions, the structure around the bearing, understand the situation before and after the accident, and investigate the damage state of Countermeasures the bearing and several causes, we can prevent the recurrence of similar accidents.

Precautions for the use of NSK Bearings are as follows:

Keep NSK bearing and its turnover clean

Even small dust that cannot be seen by the eyes will have a bad impact on NSK Bearings. Therefore, keep the surroundings clean so that dust will not invade NSK Bearings.

Use with care

Strong impact on NSK bearing in use will produce scars and indentation, which will become the cause of the accident. In case of serious crack, attention must be paid to it.

Use appropriate NSK operating tools

Avoid replacing with existing tools and bearing tools, and appropriate tools must be used. We often emphasize the importance of tools because too many customers use the wrong tools in installation, resulting in the damage of NSK Bearings.

Pay attention to the corrosion of NSK bearing

When operating NSK Bearings, sweat on your hands can be the cause of rust. Pay attention to operate with clean hands and wear gloves as much as possible.
