Industrial Extreme Pressure Gear Oil L-CKD (ISO VG 150 / 220 / 320 / 460)
Engineered from premium solvent-refined and hydrotreated paraffinic base oils with advanced sulfur-phosphorus EP chemistry, delivering micro-pitting resistance, FZG scuffing failure stage > 12, and extreme shock load protection for enclosed gearboxes.
Tribological Standard Definition & Engineering Direct Answer
FOSS L-CKD Industrial Extreme Pressure Gear Oil is a premium heavy-duty enclosed gearbox lubricant formulated from high-viscosity-index Group II paraffinic base stocks and a thermally stable sulfur-phosphorus extreme pressure additive system. Fully compliant with DIN 51517 Part 3 (CLP), ISO 12925-1 (CKD), AGMA 9005-E02 (EP), and US Steel 224 standards, it provides exceptional load-carrying capacity with a Timken OK Load exceeding 60 lbs (ASTM D2782) and an FZG scuffing test rating exceeding failure stage 12 (DIN 51354 / ISO 14635-1 A/8.3/90). The fluid features active micro-pitting protection (FVA 54/7 rating >= 10), outstanding demulsibility (ASTM D1401 water separation under 15 minutes at 82°C), non-corrosive behavior toward yellow metals (ASTM D130 rating 1a), and complete elastomeric seal compatibility. Designed for continuous operating sump temperatures from -10°C to +110°C in heavy-duty helical, bevel, planetary, and spur gear drives. Supplied in export UN 208L cold-rolled steel drums and 1,000L IBC totes.

Primary Industrial Applications & Gearbox Compatibility
Engineered specifically for high-stress industrial machinery, minimizing friction coefficients and extending component service life.
Mining & Quarry Conveyor Drives
Protects high-torque reduction gearboxes driving overland belt conveyors, ball mills, and crushers against severe shock loads.
Steel Rolling Mill Gear Reducers
Prevents tooth spalling and gear surface micro-pitting under extreme torque reversals and continuous radiant heat.
Cement Plant Ball Mills & Kilns
Maintains thick hydrodynamic and boundary lubricant films on heavy helical and planetary reduction drives.
Extruders & Rubber Calender Drives
Resists thermal sludge formation and keeps bearings clean under long continuous duty at 90°C to 105°C.
Batch Quality Control & Standard Verification
Strict five-stage quality checkpoint from raw base oil tank unloading to finished drum sealing.
FZG Gear Test Rig Verification
Additive packages audited to guarantee failure load stage > 12 without scuffing.
Sulfur-Phosphorus ICP Elemental Audit
Active phosphorus (> 250 ppm) and active sulfur treat levels confirmed for every batch.
Water Separation & Demulsibility Testing
ASTM D1401 test guarantees water phase separation in under 15 minutes at 82°C.
Traceable Retained Samples (24 Months)
1L sealed archival samples stored under temperature-controlled retention for 2 years.
Export Packaging, Palletization & Container Loadability
