Tips of changing the washing machine bearing

After the washing machine bearing is removed, first observe whether there are cracks, rust, scars on the rolling element, the inner ring and outer ring of the bearing. Then hold the inner ring of the bearing by hand and level the bearing, and rotate the outer ring of the bearing with the other hand. If the bearing is good, the outer ring should rotate smoothly and gradually decelerate to stop. There is no vibration or obvious stagnation during the rotation. After the rotation, the outer ring does not reverse. If the bearing is defective, noise and vibration will appear when it rotates. It will be abrupt like a brake when it stops, and it will reverse backwards seriously. Such bearings should be replaced.　　
The radial clearance of the washing machine bearing is 0.01 mm-0.02 mm. Push the inner ring in all directions. If the gap is felt when pushing, then the bearing wear is severe.
Before installing the washing machine bearing, it should be cleaned and checked for flexibility and smoothness, and greased. Then, ZYS washing machine bearing is placed on the journal, and a sleeve is used to hold the inner ring of the bearing. The upper end of the sleeve is iron-plated and hammered until the bearing is in place. When knocking, pay attention to the fact that the bearing can not be skewed, and the tap should be facing the axial direction.
