TRUEGARD SYN 680 is a premium synthetic industrial lubricant specifically designed for demanding environments where extreme pressure and elevated temperatures are commonplace. Featuring an ISO 680 viscosity grade, this lubricant provides optimal protection and performance in heavy-duty applications such as gears and bearings.

Advanced Formulation

TRUEGARD SYN 680 is formulated using a sophisticated blend of polyalphaolefin (PAO) and ester base oils. This combination ensures superior thermal stability, enhanced oxidation resistance, and reliable lubrication under severe operating conditions. The synthetic base oils help maintain consistent viscosity and film strength, even in fluctuating temperature ranges.

Performance Benefits

·      Extreme Pressure Protection: Delivers robust load-carrying capabilities, minimizing wear in gear and bearing systems subjected to heavy loads.

·      High-Temperature Stability: Maintains performance integrity in high-heat environments, reducing the risk of lubricant breakdown and equipment failure.

·      Anti-Wear Properties: Protects critical components from abrasive wear, extending equipment life and reducing maintenance costs.

·      Anti-Corrosion Protection: Guards against rust and corrosion, even in the presence of moisture or harsh contaminants.

Applications

TRUEGARD SYN 680 is ideally suited for industrial gearboxes, bearings, and other machinery operating under heavy loads and high temperatures. It is recommended for use in manufacturing plants, processing facilities, and other environments where reliability and equipment protection are paramount.

Frequently asked questions

Find answers to common questions about our products and services
  • ISO 680 is one of the highest viscosity grades in the ISO system, meaning the oil is very thick and designed for slow-speed, heavily loaded gear systems and large industrial bearings. If your equipment manufacturer specifies an ISO 680 or equivalent high-viscosity lubricant, this product is appropriate; for higher-speed or lightly loaded applications, a lower ISO grade would typically be required.

  • PAO (polyalphaolefin) base oil delivers excellent thermal stability and consistent viscosity across fluctuating temperature ranges, while ester base oils contribute enhanced lubricity and load-carrying capacity under severe conditions. Combining both types produces a formulation that outperforms either base oil alone in extreme pressure and high-temperature environments.

  • Synthetic base oils such as PAO and ester resist oxidation and thermal breakdown far more effectively than mineral oils, helping maintain film strength and viscosity under sustained heat and heavy loads. This results in better component protection, reduced deposit formation, and the potential for extended service intervals compared to conventional mineral oil lubricants.

  • TRUEGARD SYN 680 is specifically designed for both industrial gearboxes and bearing systems, making it suitable for facilities seeking a single high-viscosity synthetic lubricant to cover multiple heavy-duty components. Its extreme pressure protection and anti-wear properties address the distinct demands of both gear and bearing applications.

  • The formulation guards against rust and corrosion even when moisture or harsh contaminants are present, which is particularly important in processing facilities where water ingress or chemical exposure is a risk. This protection helps preserve the integrity of gearbox housings and bearing surfaces, extending overall equipment service life.

  • The product data does not indicate food-grade certification or suitability for open-gear or outdoor use. TRUEGARD SYN 680 is recommended for enclosed industrial gearboxes, bearings, and heavy-duty machinery in manufacturing plants and processing facilities. Consult the equipment manufacturer's specifications to confirm the correct lubricant type for any specialized or open-gear application.
