The Gear Oils are the industrial lubricants made exclusively for transmittal, transfer cases and operations in trucks, automobiles and other kindred machinery. These are the high viscosity oils that are included with organosulfur compounds. They remain thermally stable and donât get oxidized at high temperatures. In this way, they can also avoid the creation of varnish or precipitate. The Gear Oils are fluid lubricating substances utilized in gearboxes so as to lessen the wear & friction of the gear tooth surfaces. Also, they ensure rust protection of the gear parts as well as removal of the heat made by the operational gear.
