ISO VG 320 industrial gear oils are necessary for the seamless operation of heavy duty, industrial gearboxes. Weight refers to the oil’s viscosity.
ISO VG 320 gear lubricants have a midpoint kinematic viscosity of 320 mm2/s, also referred to as centistokes (cSt). This is the average of the minimum and maximum viscosities derived from AGMA testing (288 mPa.S and 352 mPa.S for AGMA 6).
