TRUEGARD Gear Oil 460 - 5 Gallon Pail

ISO VG 460 is a high-viscosity grade, meaning the oil is relatively thick at operating temperature. TRUEGARD's product data identifies the thicker grades in this line as exceptional worm gear oils, where high viscosity is needed to sustain a protective film under the sliding-contact conditions typical of worm gear sets.

Yes. The oil achieves its extreme pressure lubricity without the use of active sulfur, which is the additive type known to chemically attack and stain bronze or other yellow-metal components. This makes it compatible with gearboxes that incorporate bronze worm wheels, bushings, or similar parts.

Standard machine oils often lack the extreme pressure (EP) properties needed for highly loaded contact conditions. TRUEGARD Gear Oil 460 is specifically formulated with EP lubricity to handle heavy-duty, continuous operation and shock loading on industrial steel and bronze gearing, as well as highly loaded bearings where conventional oils fall short.

The formulation includes superb oxidation inhibition and resistance to viscosity loss, giving it exceptional high-temperature stability and long service life. This is particularly important in continuous-duty industrial applications where gear oil temperatures can rise significantly over extended operation.

In addition to extreme pressure lubricity, TRUEGARD Gear Oil 460 offers rust protection to guard metal surfaces against corrosion and anti-foam properties to prevent aeration - both critical for maintaining a consistent and reliable lubricating film inside industrial gearboxes.

Yes - the TRUEGARD Gear Oil line spans multiple viscosity grades. The product data notes that lighter grades are suitable for highly loaded bearings and applications where EP properties are needed but a thinner film is acceptable, while thicker grades such as the 460 are recommended for worm gear applications. Consult the gearbox manufacturer's specifications to confirm the correct ISO VG grade for your equipment.
