Problems related to original NSK imported bearings?
After NSK imported bearings have been running for a period of time, it is inevitable that there will be a demand for maintenance or damage replacement. In the early stage of the development of the machinery industry, the popularity of professional knowledge is not enough and the awareness of safe operation procedures is not enough. Today, Xiaobian will talk to you about the knowledge of bearings.
The bearing models we recommend for you are 6901zz, 16001, 6001, 6001ddu, 6201, 6201zz, 6201vv, 6802vv, 6902 and 6902zz.
NSK Bearings are widely used in mining geophysical instruments, aeration equipment, booster pump, welding table, low-noise cooling tower, oil cooler, linear guide rail, copper smelting equipment, plate shears, hand wheels, etc.
What are the advantages of bearing grease lubrication

1. The lubrication device is simple. If sealed bearings or unsealed bearings that do not require grease replenishment are used, no additional lubrication devices are required (in contrast, the oil lubrication system requires oil pumps, oil pipes, oil tanks, etc.).

2. The lubricating grease is not easy to leak, and the sealing structure of the bearing is relatively simple,

3. The bearing is easy to maintain.

4 the grease has a sealing effect, which can prevent external dust, moisture and other impurities from invading the bearing.

5. It is easy to improve the cleanliness of mechanical devices.

Imported bearings have high hardness and elastic modulus. The high hardness of silicon nitride rolling element can improve the wear resistance, stiffness and service life of bearing in polluted environment. When the steel rolling element over compacts solid pollutants, due to plastic deformation, indentation with raised edges will be formed in the raceway and on the rolling element. As the rolling element continues to over roll the raised edge, higher local stress will lead to spalling and premature bearing failure. However, mixed ceramic bearings react differently to over rolling damaged areas. Due to the high hardness of silicon nitride, the rolling mill will grind the convex edge of the indentation until the raceway returns to smoothness, which will reduce the local stress and the chance of spalling, thus significantly prolonging the service life of the bearing.
