After the INA bearing is installed, if the alignment is not carefully carried out, the alignment may cause the INA combined bearing to suffer additional load, friction and vibration. These may accelerate fatigue and reduce the service life of bearings, and may damage the service life of other machine parts. In addition, increased vibration and friction can greatly increase energy consumption and the risk of premature failure.
When the INA bearing is removed for inspection, the appearance is recorded by photography and other methods. In addition, confirm the amount of remaining lubricant and sample the lubricant, and then clean the bearing.
A. The cleaning of bearings is divided into rough washing and fine washing, and a metal mesh frame can be placed at the bottom of the container in use.
B, rough washing, in the oil with a brush to remove grease or adhesive. At this time, if the INA bearing is rotated in the oil, it will be noted that the rolling surface will be damaged due to foreign bodies.
C. When cleaning, slowly turn the bearing in oil, and it must be carried out carefully.
The cleaning agent usually used is neutral water-free diesel oil or kerosene, and sometimes warm lye is used according to the need. No matter which cleaning agent is used, always filter to keep clean.
