Our L-CKC Medium Load Closed Gear Oil is a practical and reliable lubricant made for medium-load closed gear drive systems in various industries.

Blended with deeply refined high viscosity index base oil and premium multi-functional additives, it's engineered to tackle the daily wear and tear of gears, keep equipment running smoothly, and cut down on unexpected maintenance for your machines.

It meets the national standard GB 5903-2011, and works well for low to medium speed gear devices with tooth surface contact stress below 1100MPa.

Product Features

• Strong extreme pressure and anti-wear performance, preventing gear surface scuffing and wear
• Good oxidation and thermal stability, slowing down oil aging and extending oil change cycle
• Effective rust and anti-emulsification ability, protecting parts from corrosion even with a little water mixed in
• Excellent anti-foam property, forming a stable oil film for good lubrication and heat dissipation
• No corrosion to common gear materials, suitable for most industrial gearbox types
