Bearing performance analysis

Bearing process performance analysis source: bearing | last updated: - 2020 10 - 20 bearing performance analysis according to the bearing inner and outer circle cross section and the steel ball after cleaning, can be found: the inner and outer raceway guard position find exquisite radial pressure seal, as part of the region are air oxidation 'blue'. And then again bearing experienced a very high temperature environment. According to the cold acid bearing raceway surface after cleaning, we clearly see the inner and outer raceway already serious damage, and show a radial pattern shape, concentrated in the side of the cross section, and the section management center is not significant, showed that axial force of the bearing under relatively large. For double concave groove ball bearing, it can bear the axial force of relativity, smaller than a double row angular contact bearing is able to bear axial force is much smaller. Can clearly see the bearing steel ball surface scratch is more serious, in which there are 3 sets of bearing of the bearing steel ball surface is red, suggests that this three sets of bearing experienced a very high temperature environment. Who read this article also browse: bearing sealing lip inspection sealing lip for bearing grease maintenance efficacy is critical, once the lack of sealing lip seal features for bearing grease maintenance effect is greatly reduced, so is very fatal for bearing. In detection using invalid before and after the invalid bearing sealing lip mutatis mutandis found invalid bearing sealing lip because of damage to natural environment and the high temperature to soften, loss of the existing sealing characteristics, especially in office in the high temperature environment as the foundation of sealing properties. Invalid bearing ring is completely destroyed, completely lose sealing characteristics, it will speed up the bearings is invalid.
