Oil GT-50 for hydrodynamic transfers of diesel locomotives is the low-viscosity mineral oil of deep selective clearing containing a composition of additives, improving antioxidizing, antiwear, anticorrosive and antifoamy properties.
Possesses good lubricant ability, high thermooxidizing stability and stability of viscosity. Used to greasing turbo-reducer hydrotransfers of diesel engines-trains.

Data on operational temperatures represent values which are guided by a structure of lubricants, and also on a scope and technology of use. Depending on a kind of mehaniko-dynamic loading lubricants change the consistence, conditional viscosity or viscosity at various temperatures, pressure and duration of operation. These changes of indicators can affect work of components.
