SKF non-standard bearing surface quality analysis

Source: SKF non-standard bearing surface quality analysis bearing | last updated: - 2020 08 - Several methods of 25 professional tutor you bearing rust 1) Surface cleaning: cleaning must be rust in accordance with the nature of the surface and the conditions, select the appropriate method. There are usually used solvent cleaning, chemical cleaning and mechanical cleaning. 2) Surface available filter after dry clean dry compressed air blow dry, or in 120 ~ 170 ℃ dryer for drying, also can use clean cloth to wipe dry. Bearing surface quality analysis based on the bearing inner and outer circle of the channel and the ball after cleaning, can be found: inner and outer ring raceway guard parts found fine axial indentation, parts with oxidation 'blue' phenomenon. Thus again bearing has experienced a very high temperature environment. Through the cold acid on bearing raceway surface after cleaning, we clearly see the inner and outer ring raceway has been severely damaged, and the axial stripes, concentrated in the side of the channel, and channel center is not obvious, that axial force of the bearing is relatively large. For double deep groove ball bearings, which can withstand the axial force is relatively small, more than double row angular contact bearings can withstand axial force is much smaller. Can clearly see the steel ball surface scratches, there are 3 sets of bearing steel ball surface, to illustrate the three sets of bearing experienced a very high temperature environment.
