NSL INDUSTRIAL GEAR POWER 320, 20L

NSL Industrial Gear Power 320 is a high-performance extreme-pressure (EP) industrial gear lubricant in the ISO VG 320 viscosity grade. It is specifically formulated for heavy-duty enclosed gear systems operating under severe conditions, including high loads and shock loading. Blended with premium virgin mineral base stocks and a specialized additive package, it provides robust wear protection, excellent thermal stability, and resistance to oxidation and corrosion. Designed for reliable long-term operation and extended equipment life, NSL Industrial Gear Power 320 is suitable for a broad range of industrial and marine gear applications where an ISO 320 EP gear oil is required.

Core Characteristics

• Formulation: Formulated with high-quality virgin mineral base oils and an advanced additive system (including EP, anti-wear, anti-oxidation, anti-rust, and anti-foam additives) for comprehensive gear protection.
• Extreme-Pressure Performance: Provides outstanding extreme-pressure load-carrying capability (FZG load stage ≥ 12) to shield gear teeth from scuffing and wear under heavy or shock loads.
• Viscosity Grade: ISO VG 320 viscosity grade (typical ~320 mm²/s @ 40°C and 23.8 mm²/s @ 100°C) with a viscosity index of ~94, ensuring stable lubrication viscosity across normal operating temperatures.
• Thermal/Oxidation Stability: Exhibits high thermal and oxidative stability, minimizing sludge and varnish formation for cleaner operation and extended oil service life.
• Corrosion Protection: Provides effective rust and corrosion protection for all internal components, guarding both steel and yellow-metal surfaces (e.g. bronze, brass) from degradation.
• Demulsibility: Delivers excellent demulsibility (rapid water separation) to maintain lubricant performance in the presence of moisture or water contamination.
• Temperature Range: Offers a broad operating temperature range, with a low pour point (~ –12 °C) for cold-start fluidity and a high flash point (> 200 °C) for safe performance at elevated temperatures.

Performance Benefits

• Extended Component Life: Prolongs gear and bearing life by preventing scuffing, scoring, and even micropitting wear on gear teeth, ensuring gears are protected under heavy or shock loading conditions.
• Longer Oil Service: Enables extended oil drain intervals and fewer lubricant changes thanks to outstanding oxidation stability and deposit control, which keep the oil fresher and components cleaner over time.
• Reduced Maintenance Downtime: Reduces maintenance costs and downtime by protecting critical components against wear and corrosion-related failures, thus improving the reliability of gear systems.
• Reliability in Harsh Conditions: Ensures consistent lubrication even in adverse conditions by rapidly separating water and controlling foam, thereby preventing performance issues caused by moisture ingress or air entrainment in the oil.

Applications / Area of usage

• Industrial Gearboxes: Enclosed industrial gear drives (spur, helical, bevel, and planetary gearboxes) in heavy machinery such as steel mills, crushers, extruders, conveyors, and other equipment operating under high-load conditions.
• Worm Gears: Worm gear drives and other gear sets involving steel-on-bronze (yellow metal) contact that require a non-corrosive EP lubricant to protect soft metal components.
• Bearings & Couplings: High-load industrial bearings and gear couplings lubricated by circulating oil systems, for example in paper mills, mining and cement plants, where an ISO VG 320 EP oil is specified.
• Marine Equipment: Marine gearboxes and other shipboard machinery (e.g. propulsion drives, winches, thrusters) requiring a heavy-duty ISO 320 EP gear oil for reliable operation in marine environments.
