ISO VG 68, AGMA 2, SAE 20wt. Gear Oil

ISO VG 68 industrial gear oils are necessary for the seamless operation of heavy duty, industrial gearboxes. Weight refers to the oil’s viscosity. 

ISO VG 68 lubricants (also AGMA 2, SAE 20wt) have a midpoint kinematic viscosity of 68 mm2/s, also referred to as centistokes (cSt). AGMA 2 lubricants have a minimum viscosity of 61.2 mPa.s and a maximum viscosity of 74.8 mPa.s. These numbers determine a fluid’s resistance to flow (viscosity).
