Installation or replacement of SKF bearings need to be aware of several methods

Generally, SKF bearing temperature above 150 ° is called high temperature bearings, since chromium bearing steel in use when temperature exceeds 150 °, sharp decline in its hardness, dimensional instability, SKF bearings do not work properly. So for operating temperature from 150 ° to 350 ° conditions of bearings, rings and rolling elements still use ordinary high-carbon chromium bearing steel, bearing components must be special tempering process shall normally be carried out under the above operating temperature 50 ° tempering. After tempered bearing steel according to the above requirement, can work in temperatures under normal use. But due to the decrease in hardness after tempering, decreased bearing life. When the bearing operating temperature higher than 350 °, must be manufactured using high temperature bearing steels.
General bearing steel with high temperature bearings in addition to performance, but should also have some hot hardness and high temperature wear resistance, high temperature fatigue strength of lifting, high temperature oxidation resistance, high temperature resistance, impact resistance and dimensional stability.
When SKF bearing rotation time, SKF bearing inner ring and outer ring raceways due to contact with the rolling elements are rolling, and running track to the dark side of, the track attached to the Raceway surface is not in the exception, which may be able to tell the load conditions, so when when disassembling bearing, strict attention and observation of Raceway surface running track.
Before installation, opening the SKF bearing package. Lubricating grease for general lubrication, no cleaning, fill the grease directly. Are lubricated by lubricating oil, nor does ordinary cleaning, however, equipment or bearings for high speed,
To use clean oil wash, remove rust inhibitor applied to the SKF bearing. Get rid of rust the bearing, easy to rust, so cannot be placed in the air. Into the bearings with grease, you can not clean direct uses.
