Imported bearing running track method

When the inlet bearing rotates, the raceway surface of the inner ring and the outer ring of the imported bearing is in rolling contact with the rolling element, so the running track is a dark surface, and the running track attached to the raceway surface is not an abnormality, and thus can be changed. Know the load conditions, so when disassembling the imported bearings, please pay close attention to and observe the running track of the raceway surface.

If you carefully observe the trajectory, you will know that you only bear radial loads, withstand large axial loads, withstand moment loads, or have extreme rigidity in the bearing housing. It is possible to check whether the bearing has an unexpected load and the installation error is a national or not, and it is a clue to investigate the bearing damage.

How to clean the imported bearings?

     Bearings hardened by soft dry oil or rust-proof paste should be immersed in hot oil of 100-200 ° C. Clamp the bearing with pliers and brush the oil on the bearing with a brush. The soft dry oil or rust-proof paste is melted when heated to 100-200 ° C, and is easily washed out from the bearing hole. Occasionally, the bearing should be shaken several times in the oil. Oil stains will also flow away from the loopholes (the rollers, the bead frame, the inner ring and the outer ring should also be disengaged when washing). Soak the bearing in the oil for 5-10 minutes, hold the inner ring with one hand, and the other. When the hand rotates the outer ring, the dry oil or rust-proof paste on the bearing will be lost. Then put the bearing into the cleaner oil, brush it with a gold brush, wash the oil in the ball and the hole, then put it in the gasoline for 1 time, take it out and put it on clean paper.
     When cleaning spherical ball bearings and short cylindrical roller bearings, the balls, bead frames, inner rings and outer rings should be removed.
