TRUEGARD Gear Oil EP 100 - 5 Gallon Pail

This oil is formulated for heavy-duty, continuous operation and shock loading on all types of industrial steel and bronze gearing. The EP 100 viscosity grade is also suitable for highly loaded bearings where standard machine oils lack the necessary extreme pressure properties.

EP' stands for Extreme Pressure, meaning the oil contains additives that form a protective film under high-load or shock-load conditions where conventional oils would break down and allow metal-to-metal contact. This makes it critical for industrial gearboxes subjected to heavy or intermittent shock loads.

Yes. TRUEGARD Gear Oil EP 100 achieves its extreme pressure lubricity without the use of active sulfur, which means it will not chemically react with, corrode, or stain bronze gear components - a known risk with some active-sulfur EP oils.

The lighter grades are recommended for highly loaded bearings where common machine oils are insufficient, while the heavier (thicker) grades are specifically noted as exceptional worm gear oils. EP 100 is a mid-range viscosity suited to general industrial steel and bronze gearing under continuous or heavy-duty operation.

This oil exhibits superb oxidation inhibition and resistance to viscosity loss, delivering exceptional high-temperature stability and extended service life. This helps reduce the frequency of oil changes and maintains consistent lubrication performance in demanding industrial environments.

Yes. The oil includes both rust protection and anti-foam properties, guarding gearbox internals against corrosion and preventing foam buildup that could degrade lubrication film thickness and effectiveness.
