ISO VG 220, AGMA 5, SAE 90wt. Gear Oil

ISO VG 220 industrial gear oils are necessary for the seamless operation of heavy duty, industrial gearboxes. Weight refers to the oil’s viscosity. 

ISO VG 220 gear oil has a midpoint kinematic viscosity of 220 mm2/s, also referred to as centistokes (cSt). AGMA 5 lubricants have a minimum viscosity of 198 mPa.s and a maximum viscosity of 242 mPa.s. These numbers refer to the standard testing mechanisms used to determine an oil’s resistance to flow (viscosity).
