Industrial Gear Oil ISO 680 CKD EP | 200L

Sinopec L-CKD 680 Heavy Duty Industrial Gear Oil is a high-performance extreme pressure gear lubricant formulated from high-quality mineral base oils and an advanced multifunctional EP additive system. ISO VG 680 is the heaviest standard grade in the industrial EP gear oil range, specified for the largest, slowest-speed and most heavily loaded enclosed gearboxes where maximum viscosity and oil film thickness are essential for reliable gear protection under severe operating conditions. The L-CKD 680 provides a viscosity index of 102, flash point of 270°C and pour point of -9°C, with FZG scuffing performance at load stage 12+, Four Ball EP weld load of 315kg, load wear index of 587 and Timken OK load of 60lb. David Brown S1.53.101 approved.

The 200L drum is the standard supply format for large industrial gearbox applications, suited to maintenance departments servicing large slow-speed enclosed gear drives and circulating systems on scheduled maintenance intervals.

Key Features

• Extreme pressure and antiwear performance. FZG fail load stage 12+, Four Ball EP weld load of 315kg, load wear index of 587 and Timken OK load of 60lb provide maximum load-carrying capacity for the largest and most heavily loaded slow-speed gear drives in severe industrial service.
• Oxidation and thermal stability. Advanced antioxidant chemistry minimises sludge and varnish formation at elevated bulk oil temperatures in large continuously operating gearboxes, extending drain intervals and reducing maintenance costs in high-criticality applications.
• Corrosion protection. Passes ASTM D665B rust prevention in synthetic sea water with a copper corrosion rating of 1b, providing reliable protection for ferrous and non-ferrous components in the most challenging industrial environments.
• Water separation. Rapid demulsibility at 82°C ensures effective separation of water contamination from large gearbox sumps, preventing emulsion formation and protecting gear and bearing surfaces in high-humidity industrial environments.
• Foam and air release. Low foaming tendency across all three ASTM D892 sequences maintains optimum oil film thickness in large-volume gearbox systems and reduces the risk of wear and leakage in the most demanding applications.
• Seal compatibility. Compatible with common elastomeric seal materials used in large enclosed industrial gear drive systems, minimising leakage and extending seal service life.

Applications

Sinopec L-CKD 680 Heavy Duty Industrial Gear Oil is recommended for the largest, slowest-speed and most heavily loaded enclosed gear drives in severe industrial service where ISO VG 680 is specified by the OEM or site maintenance schedule. Typical applications include large open-pit mining gearboxes, ball mill and SAG mill drives, large rotary kiln and dryer drives, sugar mill roller drives and extreme-duty industrial gearboxes in steel, cement and chemical processing. Also suitable for plain and antifriction bearings and large circulating oil systems in heavy industrial equipment.
