In comparison to mineral oils, these products are particularly suitable for high temperature lubrication of gears and bearings, for example, in calenders. In worm gears that are operated with mineral oil at a low speed and high torque in the boundary lubrication region, it often comes to pitting and consequently to rapid wear of the worm gears. Two-component machine paints that are compatible with PAG are available to the market. (Avoid phenolic coatings). Sealing of natural rubber, cork and leather are not compatible. Good rinse when changing products with low mineral oils ensures safety. Water entry in water-soluble PAG reduces the viscosity. Water content has no significant impact on bearing corrosion. Depending on the application, the total cost can be low. Not for aluminum / steel tribological contact surfaces recommended (chemical wear).
