Hydraulic Systems operate at high temperatures, pressures, and speeds and, as such, require anti-wear (AW) lubricants that protect these expensive system components from abrasion due to metal-to-metal contact, rust, and corrosion. Antiwear hydraulic oils are formulated from the highest-quality base fluids and unique additive technologies to prevent wear and tear on hydraulic systems.
ISO VG 100 oil has a midpoint kinematic viscosity of 100 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 100 oil, those numbers are 90.0 cSt and 110.0 cSt, respectively. These numbers refer to the standard testing mechanisms used to determine how much resistance to flow (i.e. viscosity) these oils demonstrate.
