TRUEGARD SYN 320 is a premium synthetic gear oil meticulously formulated to meet the demanding requirements of severe industrial environments. This advanced lubricant is designed to deliver superior protection and reliable performance across a wide range of operating temperatures, making it an ideal choice for critical gear systems and heavily loaded bearings.

Formulation and Technology

TRUEGARD SYN 320 utilizes a combination of high-quality polyalphaolefin (PAO) and ester base oils. This unique blend provides outstanding thermal stability and excellent film strength, which are essential for maintaining optimal lubrication under extreme pressure and fluctuating temperature conditions. The advanced formulation ensures minimal wear, even in the most challenging industrial settings.

Key Features and Benefits

·      Exceptional Wear Protection: Offers robust defense against metal-to-metal contact, reducing gear and bearing wear for prolonged equipment life.

·      Superior Oxidation Resistance: Resists oil degradation and sludge formation, supporting extended drain intervals and consistent performance.

·      Wide Temperature Range: Maintains viscosity and protective properties in both high and low temperature operations, ensuring reliable gear function year-round.

·      Long Service Life: Engineered for durability, TRUEGARD SYN 320 helps lower maintenance costs and downtime by providing dependable lubrication over extended periods.

·      Ideal for Enclosed Gears & Heavily Loaded Bearings: Specially formulated to meet the rigorous demands of enclosed gearboxes and bearings subjected to heavy loads and shock stresses.

Applications

TRUEGARD SYN 320 is recommended for use in a variety of industrial gear systems, including helical, bevel, and worm gears, as well as bearings operating under severe load and temperature conditions. Its versatility and robust protection make it suitable for manufacturing plants, mining operations, steel mills, and other heavy-duty industrial settings.

Frequently asked questions

Find answers to common questions about our products and services

  • ISO VG 320 is a high-viscosity grade, meaning the oil forms a thicker lubricating film suited for heavy loads, low-to-moderate operating speeds, and larger gear clearances. To confirm it is the correct grade, check your gearbox OEM documentation for the recommended ISO viscosity grade - using a grade that is too low can result in film breakdown under heavy loads, while one that is too high may cause churning losses.

  • Mixing lubricants is not recommended, as doing so can dilute or interfere with the additive package and reduce the oil's protective performance. When converting to TRUEGARD SYN 320 from a mineral or different synthetic oil, the system should be drained and flushed thoroughly before filling with the new lubricant to preserve the full benefit of its PAO and ester formulation.

  • PAO provides excellent thermal stability and a wide usable temperature range, while ester base oil enhances lubricity for sliding-contact applications, improves additive solubility, and boosts film strength under extreme pressure. The combined formulation is particularly advantageous for worm gears, which rely on sliding contact and benefit from the ester's additional lubricity that PAO alone may not fully provide.

  • Because synthetic PAO and ester base oils resist thermal and oxidative degradation far better than mineral oils, the lubricant retains its viscosity and additive effectiveness significantly longer before breaking down into sludge or varnish. This directly supports extended drain intervals, reducing the frequency of oil changes, associated labor costs, and unplanned downtime in heavy industrial operations.

  • Yes, the product is specifically listed as suitable for worm gears. The ester component in the base oil blend provides the enhanced film strength and lubricity required for the high sliding loads and bronze or steel worm wheel contacts typical of enclosed worm gear drives.

  • The product data does not indicate any NSF H1 or food-grade certification, so TRUEGARD SYN 320 is intended strictly for industrial applications where incidental food contact is not a concern. Applications such as manufacturing plants, mining, and steel mills represent its intended use environments.
