Food Grade (H-1) Gear Lubricants are developed for use in gear drives operating in food processing and beverage plants where incidental food contact may occur and meet the current requirements of USDA guidelines. PSC only offers Food Grade (H-1) Gear Lubricants that are Kosher, Halal, and CFIA certified. Petroleum Service Company's Food Grade (H-1) Gear Lubricants are fortified only with the necessary additives to keep gearboxes running smoothly for long durations while guaranteeing the safety of our oils should they come into contact with food products. 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. 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.
