Axial oil 3 (GOST 610-72) - is made of low-sulfur naphthenic and naphthene-paraffin oils. It is a combination of distillate petroleum fractions. It is used mainly in winter for lubricating the wheel pair pins necks on railway rolling stocks, as well as friction units and some low-loaded gearboxes of industrial equipment.
