Product description

Groxx Heavy-Duty Industrial Gear Oil | GGRXHVGO-10
The Groxx GGRXHVGO-10 (ISO VG 460 / DIN 51517-3 CLP grade) is an ultra-high-viscosity, heavy-duty industrial gear lubricant engineered specifically for heavy-load gearboxes, primary traction hoist drive reducers, and high-pressure industrial machinery. Formulated with advanced extreme-pressure (EP) additives and superior anti-wear chemistry, GGRXHVGO-10 provides an impenetrable oil film that protects enclosed gears against micro-pitting, scuffing, and severe mechanical wear under high-torque dynamic conditions.
Core Performance & Design
  • Heavy-Duty Extreme Pressure (EP) Protection: Delivers exceptional load-carrying capability with an FZG Gear failure load stage exceeding Stage 12 and a four-ball sintering load of 2453 N, preventing gear tooth scoring under heavy shock loads.
  • Superior Anti-Wear & Shear Stability: Maintains a stable kinematic viscosity of 455.7 mm²/s at 40°C even after rigorous shearing tests, ensuring long-term film strength without thermal breakdown.
  • Thermal & Oxidation Resistance: Tested for high-temperature stability with an oxidation viscosity increase of only 2.3% after 312 hours at 121°C, preventing sludge formation and varnish buildup.
  • Corrosion & Moisture Protection: Formulated with active rust inhibitors that pass liquid-phase corrosion testing in synthetic seawater (Rust-free result) and offer excellent anti-emulsification properties to rapidly separate water from oil.

Application & Maintenance Profile
  • Primary Applications: Heavy-duty industrial gearboxes, hoist speed reducers, spur/bevel/helical gear drives, and high-load traction mechanisms operating under severe outdoor or marine environments.
  • Low-Temperature Performance: Features a low pour point of -18°C (EN ISO 3016), ensuring smooth cold-start circulation and flow without cavitation during winter operations.
  • Foam Control: Tested under EN ISO 6247 to maintain rapid foam collapse (30/0 mL at 24°C), ensuring continuous lubrication film contact across gear teeth.
The Groxx Advantage
The Groxx GGRXHVGO-10 Industrial Gear Oil is fully compliant with ISO 12925-1 (Type CKD) and DIN 51517-3 (CLP) standards to deliver unmatched equipment protection. By offering superior shear stability, high thermal endurance, and exceptional extreme-pressure performance verified by European EN ISO test protocols, Groxx ensures your industrial gear drives operate with maximum power efficiency and drastically reduced overhaul costs.
