 ... bearings, kerosene oil is the only lubricant which can be used. I think it extremely probable, that at these low temperatures, the viscosity of kerosene oil is equal to that of lubricating oils at the average temperature of bearings in general use....

...kerosene oil is equal to that of lubricating oils at the average temperature of bearings in general use. According to the results which I have obtained, the co-efficient of friction at 50° is about seventy-five per cent in excess of that at 75°, and it seems to me that the manager of every mill... | |
