INA stainless steel bearing common fault solution

Installed in institutions, INA bearing parts allowed to have a certain temperature, when the hand touch body shell, should not feel hot as normal, conversely indicates that bearing temperature is too high. The cause of the high bearing temperature are: lubricating oil quality does not conform to the requirements or metamorphism, lubricating oil viscosity is too high; The assemble tight ( Inadequate clearance) ; Stainless steel bearing assembly too tight; Bearing race in internal rotation shaft or housing; Too much load; Bearing cage or rolling body fracture, etc. The functioning of the rolling bearing in the work to allow a slight noise, if you have any abnormal noise or excessive noise or sound, suggests that the bearing failure. Cause noise of rolling bearings is more complex, one is the bearing inner and outer surface wear. Due to this kind of wear and tear, damage the bearings and shell, stainless steel bearings and the shaft cooperate relationship, lead to axis deviation from the correct position, when axis at high speed movement produces sound. When INA bearing fatigue, its surface metal flake, also can produce sound make bearing radial clearance increases. In addition, the bearing lubrication, forms the dry friction, and bearing broken etc all make abnormal noise. After bearing wear loose, loose cage damaged, also can produce sound bearing damage. 1, tile surface corrosion: spectrum analysis found that non-ferrous metal element concentration anomaly; Iron spectrum appeared a lot of non-ferrous metal components in sub-micron wear particles; Lubricating oil excess moisture, acid value exceeds bid. 2, a shaft neck surface strain: iron spectrum have iron series cutting grinding grain or black oxide particles, metal surface heat tint. 3, shaft neck surface corrosion: spectrum analysis found that iron concentration is unusual, there are a lot of iron in iron spectrum of submicron particles, water or high acid value oil paint. 4, surface strain: iron spectrum found cutting abrasive, abrasive ingredients for non-ferrous metal. 5, tile back micro wear: spectrum analysis found that iron concentration is unusual, there are a lot of iron in iron spectrum wear submicron particles, lubricating oil moisture and acid value anomalies. Impact of the rolling element and its control method for larger models of ball bearing or bearing under pure radial load speed, due to centrifugal force is lesser, roller in the rolling body will impact the load area or race and making noises. But with the increase of rotational speed, the noise will disappear. INA bearing raceway groove sound sound and its control method is when bearing is running, the roller rolling on the surface of the raceway and a line of continuous sound, is occur in all stainless steel bearing characteristic of the basic sound. General bearing ring raceway is combined with other sounds. Ball bearing raceway is irregular, frequency above 1000 hz, its main frequency does not change with speed, but the sound pressure level increases with speed to speed up.
