Correct use of lubricants, quite important for SKF bearings. How do we identify its advantages and disadvantages? I experience accumulated over the years for your reference:
1, and water of check; (1), and to lubricants injected bearing tube in the, observation transparency, if does not clear transparent and cloudy, can preliminary found lubricants in the contains water; (2), and in tube within injected about more than half of lubricants, heating to 100~120℃ around, as has sound, and and has bubble appears or tube wall condensation has drops, description has water; (3), and to no crystal water of white powder shaped of copper sulfate into with lubricants of tube in the, if copper sulfate becomes blue and precipitation Yu bottom, The lubricants contain water.
2, the granularity check (1), on the level of placing a piece of clean glass, respectively, dropping previous drops of lubricating oil and standard quality to be checked, and then tilt the glass, compare the speed and distance of two types of lubricating oil shed, large velocity, distance, note lower viscosity, whereas high viscosity. (2), and will pending check of lubricants and standard quality of lubricants respectively loaded in two support tube in the, oil surface in tube mouth 5 mm following, to tube mouth seal live, will two tube while upside down, observation bubble rose of speed, if was checked lubricants than standard lubricants bubble rose of speed fast, description the oil of viscosity than standard oil of viscosity low, instead is high.
3, lubrication performance of differential; to be friction between the thumb and index finger stained with lubricating oil, such as sticky feeling, description have good lubrication properties of the oil, if you feel Fase, explaining that the lubrication performance has degraded.
4, mechanical impurities inspection; would lubricants for gasoline dilution and filtering, observation to filter out impurities.
Correctly choose lubricating oils can not only improve the performance of SKF bearings, can extend their life.
