INA bearing need to be aware of several installation and replacement method

Usually, INA 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, displacing the bearing does not work properly. So for operating temperature from 150 ° to 350 ° work under the condition of bearings, rings and rolling selection of ordinary high-carbon chromium bearing steel, the special tempering process of bearing components must be, should normally be carried out under the above operating temperature 50 ° tempers. 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 INA bearing rotation when the bearing inner ring and outer ring raceways due to contact with the rolling elements are rolling, and running track for the dark side, track attached to the Raceway surface, not fall within 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 installing, open the INA 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 INA 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.
