Industrial Gear Oil

Even when torque is transferred, gears will have sliding and rolling contact, leading to frictional losses and heat generation. Therefore, the lubricants selected for these applications must be able to significantly reduce these frictional losses and cool the gears. Industrial gear oils can be formulated using mineral base oils or synthetic base oils.

 Various additives are incorporated into gear oils to enhance their performance characteristics and the viscosity of gear oil is a critical parameter that determines its flow characteristics and lubricating ability. The lubricant must also have a high viscosity at operating temperature such that the formed film can sufficiently support the load while cooling the gears. Another point to consider is the pour point of gear  oil ,that  refers to the temperature at which the oil begins to solidify and lose its flow properties. Available industrial gear oils can be classified into four main types are Synthetic Gear Oil, Rust and oxidation inhibited (R&O) gear oils, Extreme pressure (EP) gear oils , Compounded gear oils.
