ISO VG 100, AGMA 3, SAE 30wt. Gear Oil
ISO VG 100 industrial gear lubricants are necessary for the seamless operation of heavy duty, industrial gearboxes. Weight refers to the oil’s viscosity.
ISO VG 68 lubricants (also AGMA 3, SAE 30wt) have a midpoint kinematic viscosity of 100 mm2/s, also referred to as centistokes (cSt). AGMA 3 oils have a minimum viscosity of 90 mPa.s and a maximum viscosity of 110 mPa.s. These numbers determine a fluid’s resistance to flow (viscosity).
