ISO VG 220, AGMA 5, SAE 50, 90Wt. Oil

Description

ISO VG 220 oils (also known as AGMA 5 oils, SAE 50 oils, and 90WT Gear oils) are applicable in various industrial applications that include gearboxes, hydraulics, compressors, and slideways. Though these classification systems seem confusing and different, they all essentially stand for the same thing - a measured viscosity, or relative oil thickness. In most applications, these oil classifications are interchangeable - however, it is wise to consider OEM specifications to determine which exact lubricant specification is to be used.

ISO VG 220 oil has a midpoint kinematic viscosity of 220 mm²/s, also referred to as centistokes (cSt). The midpoint is derived by taking the average of both the minimum and maximum kinematic viscosities. In the case of ISO VG 220 oil, those numbers are 198 cSt and 242 cSt, respectively. SAE 50W oil has a minimum high-temperature kinematic viscosity of 16.3 mm²/s (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 how much resistance to flow (i.e. viscosity) these oils demonstrate.
