Abstract
1. The service life of a lubricating material in rolling [friction] can be increased by replacing the air medium by an inert gas medium or by vacuum with a small closed gas-space volume. Oils that are prone to oxidation by atmospheric oxygen show greater effects when the air is thus replaced. 2. When an inert gas medium is replaced by vacuum with an unlimited gas-space volume, the serviceability of oils is decreased, the effect being greater for high-volatility oils. 3. When the air medium is replaced by vacuum with an unlimited gas-space volume, the change in service life depends on the susceptibility of the oil to oxidation by atmospheric oxygen and on the volatility of the oil. The oil consumption rate due to oxidative processes decreases, but the oil consumption rate due to evaporation increases. The over-all result depends on the relative importance of these two factors.
