SKF bearing supplies and replacement of lubricant - bearing limited knowledge

Lubricant over time lubrication performance will weaken, new lubricant must be added after a certain interval. Additional lubrication interval, according to the bearing form, size, rotation speed, SKF bearing temperature and different kinds of lubricant need to choose a different species. Table 1 properties of lubricating oil and the exchange limit sample performance exchange limit the oil other oil was compared with the new oil viscosity change/s within 10% 25%, 10-15% is most appropriate acidification degradation, heterogeneous oil mixed with water volume % 0. 2 below 0. 2 the following dehydration after the possibility of using again the weight of the insoluble part pentane molecular % % 1.
