What are the advantages of maintenance-free bearings?

Advantages of maintenance-free bearings

1. No need to refuel, long life, can significantly reduce the frequency of bearing replacement and reduce the generation of waste.

2. Using special maintenance-free technology, there is no need to refuel and maintain the bearings. The device will not cause pollution due to continuous refueling and can maintain a clean working environment.

3. Compared with standard bearings, maintenance-free and long life can reduce CO2 emissions by 79.1%. Reduce environmental load through longer service life.

4. Long-life use can reduce the operating costs of a large number of enterprises. Even if the initial purchase cost is higher than that of standard bearings, the total cost is reduced.

After cleaning the inner and outer ring sections and steel balls of the maintenance-free bearing, it can be found that fine radial imprints are found on the inner and outer raceway ribs, and some areas are "blue" due to oxidation. This further proves that maintenance-free bearings have experienced very high temperatures. After cleaning the surface of the maintenance-free bearing raceway with cold acid, we can clearly see that the inner and outer raceways have been seriously damaged and have radial patterns, concentrated on the sides of the section, while the center of the section is not obvious. , indicating that the axial force experienced by maintenance-free bearings is relatively large. For double groove ball maintenance-free bearings, the axial force they can bear is relatively small, which is much smaller than the axial force that double-row angular contact maintenance-free bearings can bear. It can be clearly seen that the surface of the maintenance-free bearing steel balls is seriously scratched. Among them, the surface of the maintenance-free bearing steel balls of three sets of maintenance-free bearings is red, indicating that these three sets of maintenance-free bearings have experienced very high temperature environments.
