Maintenance of double row self-aligning roller bearing after use

Double row self-aligning roller bearing is a precision component, and its use must be carried out with corresponding caution. No matter how high-performance bearings are used, if they are not used properly, the expected high performance will not be obtained. Precautions for the use of bearings are as follows.
Once the double row self-aligning roller bearing moves, the inner ring takes the raceway surface of the outer ring. Because the rolling element is in rolling contact, the running track is a dark surface, and the running track attached to the raceway surface is not very important. Therefore, the load premise can be known. Therefore, under the environment of removing the bearing, what types of bearing seals are there. Please pay close attention to and observe the running track of the raceway surface. If you carefully observe the running track, you will be able to bear radial load, large axial load, torque load, or there is no extreme rigidity inequality on the bearing housing.
When removing the double row self-aligning roller bearing for inspection, first make appearance records by photography and other methods. In addition, confirm the amount of remaining lubricant and sample the lubricant before cleaning the bearing.
a. The cleaning of double row self-aligning roller bearings is divided into rough cleaning and fine cleaning, and a metal grid can be placed at the bottom of the container.
b. During rough cleaning, remove grease or adhesion with a brush in the oil. At this time, if the bearing is rotated in oil, pay attention to the damage to the rolling surface due to foreign matters.
c. During fine cleaning, slowly rotate the double row self-aligning roller bearing in oil, which must be carried out carefully.
The cleaning agent usually used is neutral water-free diesel oil or kerosene, and warm alkali liquor is sometimes used as required. No matter what kind of cleaning agent you use, always filter it and keep it clean. After cleaning, apply antirust oil or antirust grease on the double row self-aligning roller bearing immediately.
