ISO VG 10 lubricants are intended for use in industrial and manufacturing applications. These oils commonly contribute their lubrication characteristics to spindles in machine tools - these machine components are rotating, high-power mechanisms found in industrial machines that may be operating at high and low speeds. Some air-powered tools may also require an ISO VG 10 oil.
The "10' in ISO VG 10 oil stands for these oils' midpoint kinematic viscosity. In this case, this number is 10 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 10 oil, those numbers are 9.0 cSt and 11.0 cSt, respectively. These numbers refer to the standard testing mechanism used to determine how much resistance to flow (i.e. viscosity) these oils demonstrate.
As is always the case with industrial lubricants, the weight is the single most import factor in determining whether or not an oil will suit your application.
