COMPARISON OF OPERATING CHARACTERISTICS OF THE MULTIFUNCTIONAL STOU-type UNIVERSAL OIL AND CONVENTIONAL SPECIALIZED LUBRICANTS
Journal Title: Tribologia - Year 2014, Vol 257, Issue 5
Abstract
The aim of the study was to compare the operating characteristics of the multifunctional STOU-type oil (Super Tractor Oil Universal) and classic specialized lubricants produced by the same manufacturer. The study compared the tribological, rheological, and antioxidant properties using a four-ball machine, a rotational rheometer, and the Petrooxy test device. It has been found that universal oil is a Newtonian fluid and its dynamic viscosity is two times lower than the other two lubricants at positive and negative temperatures. In addition, universal oil has better antioxidant and antiwear properties than hydraulic and gear oil, but it has worse antiseizure properties than gear oil. Thus STOU-type oils can only be operated under moderate load of tribological and hydraulic systems.
