2. Soak the bearing with diesel oil or kerosene for cleaning. If there are technical conditions, it is better to open the sealing cover for cleaning;
3. Air dry cleaning oil after cleaning, and check whether there is any damage in appearance;

Soak the tested bearing in the bucket until no bubbles overflow.Remove the bearing before cooling grease, and the amount of residual grease is small.After the grease is cooled, take out the Angle and contact the ball bearing.Determine the amount of grease residue as needed.
9. Wipe the grease on the outside of the bearing with a soft cloth or toilet paper and install the miniature angular contact bearing on the pulley in its original state. The maintenance work will end immediately.
