Anti-Wear (AW) hydraulic oils are designed to drastically reduce abrasion, metal-to-metal contact, rust, and corrosion - considering the environments within which hydraulic components operate, these oils are formulated with specific additive systems to compensate for the increased pressures and temperatures. These oils are refined from high quality base fluids and are designed to maintain the integrity of hydraulic pumps.
ISO VG 150 oil has a midpoint kinematic viscosity of 150 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 150 oil, those numbers are 135 cSt and 165 cSt, respectively. These numbers refer to the standard testing mechanisms used to determine how much resistance to flow (i.e. viscosity) these oils demonstrate.
