Common sliding NSK bearing failures

Sliding NSK bearings NSK bearings that work under sliding friction. The sliding NSK bearing works smoothly, reliably and without noise. Under liquid lubrication conditions, the sliding surface is separated by the lubricating oil without direct contact, and the friction loss and surface wear can be greatly reduced, and the oil film also has a certain vibration absorbing capability. The use of sliding NSK bearings is also very versatile. How can we solve the problem of the occurrence of sliding NSK bearings? What better way? Let me explain the relevant knowledge to you, I hope to help you.

Common faults in sliding NSK bearings are as follows:

1, tile surface corrosion: spectral analysis found that the concentration of non-ferrous metal elements is abnormal; there are many sub-micron wear particles of non-ferrous metal components in the iron spectrum; lubricating oil moisture exceeds the standard, acid value exceeds the standard.

2. NSK imported bearing journal surface strain: iron spectrum cutting abrasive grains or black oxide particles in the iron spectrum, tempering color on the metal surface.

3, NSK bearing journal surface corrosion: Spectral analysis found that the concentration of iron is abnormal, there are many sub-micron particles of iron in the iron spectrum, the lubricating oil exceeds the standard or the acid value exceeds the standard.

4, NSK bearing surface strain: found in the iron spectrum cutting abrasive particles, abrasive particles are non-ferrous metals.

5, fretting wear behind the tile: spectral analysis found that the iron concentration is abnormal, there are many iron components in the iron spectrum sub-micron wear particles, lubricating oil moisture and acid value is abnormal.

SKF bearing storage method

Learn from SKF authorized dealers how to store SKF bearings

1: The storage location must be protected from moisture because the bearing will rust once it has passed through the tide.

2: SKF carton packaging should be placed on a certain specification shelf to facilitate the search and restocking

3: When transporting large bearings, use tools and forklifts to handle the goods.

4: Try not to suppress some plastic-packed goods. Because after all, it is plastic

5: Do not mix the models because the grease inside the different models is different.

6: Regular maintenance, such as cleaning some anti-rust oil frequently

7: Put some of the outer packaging of the bearing as much as possible with a cloth to prevent the bearing from entering the dust.

8: Some precision spindle bearings must be handled with care.

9: SKF packaging should not be squeezed to prevent the box from being broken when the customer will be disgusted.

10: Follow the instructions during maintenance
