ISO VG 220 | Rust & Oxidation Oil | Synthetic


Gaining a slight edge over mineral-based R&O oils, synthetic rust and oxidation oils (often intended for the lubrication of heavily-loaded rolling-element and plain bearings) are designed to provide lubrication to a variety of industrial applications including hydraulics, air and gas compressors, some circulation systems, and moderately-loaded gearboxes. These lubricants will stand the test of time and temperature, being extremely resilient to oil breakdown due to their synthetic formulation. Additionally, these oils can perform under high pressures and temperatures and can contribute to the lengthened life of industrial machines.

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. These numbers refer to the standard testing mechanisms used to determine how much resistance to flow (i.e. viscosity) these oils demonstrate.
