Narrative SKF bearing manufacturer of non-standard bearing fault often happens

Bearing manufacturer SKF non-standard bearings commonly occurs fault source: bearing | last updated: - 2020 08 - 06 narrative SKF bearing manufacturer of non-standard bearings commonly occurs fault of non-standard bearings exhibit strong regularity in the process of its use, and the repeatability is very good. Normal when start to use high quality stainless steel bearing, vibration and noise are relatively small, but there are some scattered of spectrum amplitude is small, probably because some disadvantages in the process of production, such as appearance burr. Movement after a period of time, must be vibration and noise, the spectrum is very single, only one or two times the frequency. Rarely appear more than three times the power frequency spectrum, stainless steel bearing condition is very safe, into the safe operation period. Late after running into use, the bearing vibration and noise increases start, sometimes present different tone, but with increasing of oscillation for the early stage of the problem. Bearing spectral analysis found that abnormal non-ferrous metal element concentration, and many non-ferrous metal iron spectrum of sub-micron wear particles; Lubricating oil water overruns, acid value, overruns, indicate the bearing of the tile surface corrosion; Bearing abnormal spectrum analysis found that iron concentration, there are a lot of iron in iron spectrum wear submicron particles, abnormal oil moisture and acid value, indicate the bearing tile back due to micro wear; Stainless steel bearing iron spectrum contains iron series cutting grinding grain or black oxide particles, metal surface heat tint, appearance is clearly indicate the journal bearing a strain; Bearing iron spectrum found abrasive cutting and grinding grain composition for non-ferrous metals, indicates that there are strain bearing appearance; Bearing abnormal spectrum analysis found that iron concentration, there are a lot of iron in iron spectrum of submicron particles, oil water overruns or acid value overruns, indicate the needle roller bearing shaft neck appearance by corrosion.
