ISO VG 220 oils (also referred to as AGMA 5 oils, SAE 50 oils, and 90WT gear oils) are applicable in several industrial applications including circulating systems, as well as gear boxes.
ISO VG 220 oil has a midpoint kinematic viscosity of 220 mm2/s (cSt). SAE 50W oil has a minimum high-temperature kinematic viscosity of 16.3 mm2/s (cSt). AGMA 5 lubricants have a minimum viscosity of 198 mPas and a maximum viscosity of 242 mPas. Weight refers to viscosity.
