(1) Bearing color changes

Under the condition of high load labor, the bearing will be in the state of high temperature operation, and its own color may appear black and blue changes.

The reason for this situation is that the lubrication added to the bearing is not satisfied. When the bearing is installed, the inner or outer ring of the bearing appears sliding friction, and the bearing seat hole is not concentric with the journal, which will lead to wear and tear of the bearing in the process of work.

(2) Cracks occur in the inner and outer rings of bearings

If the bearing quality is poor or the steel chosen by the bearing itself has a big problem, the bearing may have cracks in the process of high strength operation.

In addition, if suffered from a huge impact from the outside world, or in the process of installation and removal of bearings, hit by a hard object, etc., will lead to cracks in bearings.

(3) Bearing corrosion

If in the process of operation, the sealing device fails and loses its protective effect on the bearing, leading to some external liquid entering the bearing, it will lead to bearing corrosion.

(4) Broken ball bearings and pits in the raceway

Because the ball bearings installed in the process of reserved middle distance is not up to par, in the process of running, it is easy to by the huge impact, if mixed with some iron filings of lubricants and other hard objects, can lead to bearing the ball broken, in addition, if the bearing lubrication processing not in place, race to bear the friction is bigger, also can appear the situation of the raceway potholes.

(5) The working efficiency of bearings decreases

The flexibility of bearing operation is reduced, and the bearing cannot be easily rotated by hand. Most of this is because the cleaning work of the bearing is not done well, leading to insufficient pores of the journal and inner and outer rings, resulting in bearing deformation and reduced operating efficiency.
