Industrial gear systems operating under continuous, medium-load conditions require lubrication that remains stable under heat, resists surface fatigue, and protects multi-metal components. Gear Oil 100 is formulated to deliver consistent film strength and long-term operational stability in enclosed gearboxes where predictable performance and uptime matter.
Gear Oil 100 is an industrial gear lubricant developed for enclosed gear and power transmission systems operating under moderate mechanical loads. It is designed to maintain a stable lubricating film between meshing gear teeth, helping reduce frictional losses and limit surface wear during continuous operation.
In many industrial environments, gearbox failures are linked to lubricant ageing, viscosity breakdown, or inadequate surface protection. Gear Oil 100 is formulated to address these risks by balancing viscosity stability, oxidation resistance, and corrosion protection—supporting reliable gearbox operation over standard service intervals.
Gear Oil 100 is suitable for a wide range of enclosed industrial gear systems where consistent lubrication performance is required. Typical applications include:
In industrial gearbox practice, Gear Oil 100 is commonly selected for applications requiring a medium-viscosity gear lubricant, particularly where load conditions are stable and operating temperatures remain within standard industrial limits.

Selecting the correct technical parameters is critical to ensuring lubricant compatibility with gearbox design, operating temperature, and load profile. The specifications below define the intended operating window for Gear Oil 100.
These parameters align with common industrial gearbox requirements and typical OEM recommendations for moderate-load, enclosed gear systems. Final operating limits should always be verified against specific gearbox manufacturer documentation.
Gear Oil 100 provides reliable scuffing resistance and adequate load-carrying capacity for gear systems subjected to continuous, moderate loads, helping prevent premature gear tooth distress.
The anti-wear additive system forms a protective boundary layer on metal surfaces, reducing direct metal-to-metal contact during start-up and steady-state operation.
Controlled oxidation stability helps slow lubricant degradation at elevated operating temperatures, supporting viscosity retention and surface protection over extended service periods.
Stable lubrication performance contributes to smoother gear meshing, reduced vibration, and improved overall gearbox reliability.
Understanding where Gear Oil 100 performs best—and where it should not be used—is essential for protecting equipment and avoiding unnecessary maintenance risks.
If gear teeth show signs of scuffing, pitting, or abnormal load spikes, a higher-performance EP or synthetic gear oil should be evaluated instead of Gear Oil 100.
Clear selection guidance helps reduce the risk of lubricant misapplication—one of the most common causes of reduced gearbox service life.
Gear Oil 100 is formulated to meet internationally recognized expectations for industrial gear lubrication, including CLP-type performance requirements and ISO viscosity classification principles (e.g. DIN 51517-3), where referenced by equipment manufacturers.
Always confirm lubricant selection against OEM gearbox specifications prior to use.
Yes. Gear Oil 100 can be used in both splash and circulation lubrication systems for enclosed industrial gear units operating within its recommended range.
It is suitable for plain and rolling bearings where load and temperature conditions fall within the product’s intended operating window.
