Industrial gear-driven machines are often operating in high-pressure and high-heat environments and are frequently exposed to contaminants including dirt and water. Gear Oils are needed to keep these machines running smoothly in spite of the abrasive atmosphere and exposure to impurities. With the right selection of oil additives - these fluids can greatly extend systems life and increase performance.
AGMA 2 oils are also classified as ISO VG 68 oils. These oils have a midpoint kinematic viscosity of 68 mm2/s, also referred to as centistokes (cSt). The midpoint is derived by taking the average of both the minimum and maximum kinematic viscosities. In the case of ISO VG 68 oil (also AGMA 2 oil), those numbers are 61.2 cSt and 74.8 cSt, respectively. These numbers refer to the standard testing mechanisms used to determine how much resistance to flow (i.e. viscosity) these oils demonstrate.
