TRUEGARD 680 EP is a premium-grade extreme pressure (EP) industrial gear oil engineered to deliver superior protection and performance in heavy-duty machinery. Specially formulated for gears and bearings that encounter high loads and shock conditions, TRUEGARD 680 EP stands out for its robust composition and reliability in demanding environments.

Key Features

·      Extreme Pressure Protection: TRUEGARD 680 EP is fortified with advanced EP additives that form a resilient lubricating film, effectively preventing metal-to-metal contact, scuffing, and welding of gear teeth even under severe load and shock conditions.

·      High Viscosity Grade: With an ISO VG 680 rating, this oil offers a thick consistency ideal for applications where maximum protection and cushioning are required, ensuring optimal lubrication for heavily loaded components.

·      Oxidation Resistance: The formulation includes oxidation inhibitors that significantly slow down oil degradation, extending both lubricant life and machinery service intervals, and reducing maintenance costs.

·      Corrosion and Foam Protection: TRUEGARD 680 EP contains rust and foam inhibitors, safeguarding critical components against corrosion and ensuring consistent performance by minimizing foam formation.

·      Versatile Application: Suitable for a wide range of industrial uses, this gear oil excels in enclosed gear drives, bearings, and select mist lubrication systems. It is compatible with both steel and bronze gears, making it a flexible solution for various heavy manufacturing sectors.

Typical Uses

TRUEGARD 680 EP is trusted across industries such as steel mills, rubber mills, and other heavy manufacturing facilities where machinery operates under high stress. Its robust formulation makes it ideal for:

·      Industrial gearboxes subjected to extreme loads

·      Bearings in heavy-duty equipment

·      Enclosed gear drives and transmissions

·      Mist lubrication systems (where compatible)

·      Machinery utilizing steel or bronze gearing

Benefits

·      Reduces wear and extends equipment lifespan

·      Minimizes downtime through prolonged oil service intervals

·      Protects against rust, corrosion, and foaming issues

·      Ensures reliable operation in high-load, shock-prone environments

By choosing TRUEGARD 680 EP, operators benefit from enhanced machinery protection, reduced maintenance needs, and improved performance under the most challenging industrial conditions.

Frequently asked questions

Find answers to common questions about our products and services

  • ISO VG 680 is one of the highest standard viscosity grades for industrial gear oils, indicating a very thick oil designed for slow-speed, heavily loaded gearboxes where lighter oils would be pushed out of the contact zone under extreme pressure. If your equipment manufacturer specifies ISO VG 680 or a similar high-viscosity grade in their lubrication requirements, this product is appropriate; always cross-reference with your OEM documentation before selecting.

  • Yes, the product is explicitly listed as compatible with both steel and bronze gears, making it suitable for mixed-metal gearboxes. Some sulfur-phosphorus EP additives can be aggressive toward yellow metals, so this confirmed bronze compatibility is an important distinction when evaluating it for mixed-material gear trains.

  • The product listing covers enclosed gear drives, industrial gearboxes, and bearings, but does not specifically identify worm gear drives as a recommended application. Worm gears often require oils with specific anti-wear rather than aggressive EP chemistry to protect bronze worm wheels, so it is best to confirm with your equipment manufacturer before using this oil in a worm gear system.

  • The product data does not address mixing or changeover procedures, and mixing lubricants from different formulations can compromise additive packages and performance. As a general best practice, draining the existing oil and performing a flush before filling with TRUEGARD 680 EP is recommended to ensure the EP additives and inhibitor package function as intended.

  • TRUEGARD 680 EP is listed as compatible with select mist lubrication systems, though the listing specifically notes this applies only where compatible. Given its very high ISO VG 680 viscosity, you should verify with your mist lubrication system's specifications that it can atomize and deliver an oil of this thickness before use.

  • ISO VG 680 is roughly two to three times more viscous than ISO VG 220 or 320, providing a thicker lubricating film that is better suited for very slow shaft speeds and extremely high loads or shock conditions, such as those found in steel mills and rubber mills. Lighter grades like 220 or 320 are more appropriate for moderate loads and higher speeds, so the choice should be guided by your gearbox's operating speed, load rating, and OEM viscosity specification.
