Bio-Food Grade Gear Oils (ISO 32- 680)

RLI’s Bio-Food Grade™ Gear Oils are for gear drives and right angle gear drives commonly used in food processing equipment; essentially odorless and tasteless.  These gear sets do not require Hypoid level of EP and because of this the lubricants most commonly specified by makers of these gear reducers are R&O or GL-3 type circulating oils.  ISO Viscosity Grades 32, 46, 68, and 220 meet and exceeds “Military Specifications DOD-L-24651 Lubricating Oils, Food Grade, and Food Processing Equipment.”  This specification is approved for use by the Departments and Agencies of the U.S. Department of Defense.  ISO Viscosity Grades 32, 46 and 68 meet DOD-L-24651 Type I and ISO Viscosity Grade 220 Meet DOD-L-24651 Type II for general purpose and gear oil lubricants.  This specification also requires a rating of USDA H-1 for incidental food contact.

RLI’s patented formulas have improved performance over conventional products in terms of oxidation, thermal shear, and fluid film (viscosity index).  This super high viscosity index allows these products to be energy conserving in the startup mode and provide improved load protection, reducing wear during operation.  They are highly inhibited against moisture and rusting in both fresh and sea water and passes both A and B Sequences of the ASTM D-665 Turbine Oil Rust Test.  These products also provide double the oxidation stability over the US Steel 127 test requirement of 125 minutes and shows excellent performance in ASTM D-1401 Turbine Oil Demulsibility with a rating of 40/40/0 in ten minutes. 

RLI’s Bio-Food Grade™ Gear Oils have combined Stabilized technology with HOBS and food grade mild EP/anti-wear additives that exceed the load stage 10 in the FZG (DIN51354) requirements for both turbine oils and reduction gears.  The results are patented Food Grade1 products which have long life and heat stability.  Additionally, they offer the protection advantages of the mild EP and antiwear of an API “GL-3” type gear lube.  Bio-Food Grade™ Gear Oils are ENVIRONMENTALLY RESPONSIBLE biodegradablelubricants that are formulated from renewable agricultural plant resources.  We believe Earth’s environmental future rests in the use of renewable material.


(1) API Service Classifications for ashless GL-1, GL-2, GL-3

(2) Super high viscosity index and low pour point for wide temperature usage

(3) Energy Conserving Formulas  (Because of the super high viscosity index (VI) of the Stabilized HOBS these products are lighter therefore more energy efficient at room temperatures up to 40oC but provide a more protective heavier viscosity than mineral based formulas at operating temperatures of 60oC and above)

(4) Fortified with food grade additives to resist wear, oxidation, rust and foam

(5) More fire resistant and improved heat dissipation

(6) ISO14000 compliant

 1 This product is acceptable as a lubricant with incidental food contact (H1) for use in and around food processing areas. Such compounds may be used on food processing equipment as a protective anti-rust film, as a release agent on gaskets or seals of tank closures, and as a lubricant for machine parts and equipment in locations in which there is a potential exposure of the lubricated part to food.
