ISO VG 680, AGMA 8, SAE 140wt. Gear Oil

ISO VG 680 industrial gear lubricants are necessary for the seamless operation of heavy duty, industrial gearboxes. These weights refer to the oil’s viscosity. 

ISO VG 680 gear lubricants have a midpoint kinematic viscosity of 680 mm2/s, also referred to as centistokes (cSt). This is the average of the minimum and maximum viscosities derived from AGMA testing (612 mPa.S and 748 mPa.S for AGMA 8).
