It is an oil formulated with selected additives that provide a great ability to resist oxidation and thermal decomposition. In order to support the correct operation of the modern machinery and to extend its useful life, these lubricants also incorporate antiwear additives that are capable of increasing load carrying capacity of the oil film under boundary lubrication and falling friction between moving surfaces and thereby lowering the temperature and wear. These fluids are specially recommended for universal hydraulic systems and are formulated to meet the requirements of hydraulic equipment with high precision and speed.
