Tribol 1100 Range

Castrol Tribol™ 1100 gear oils with the TGOA (Tribol Gear Oil Additive) additive system represent a significant
advancement in gear oil technology. Developed for service in enclosed gear drives, journals, and antifriction
bearings, Tribol 1100 gear oils are typically used where heavy and shock load conditions prevail.
Tribol 1100 gear oils are manufactured from the highest quality petroleum base oils. Blended into this oil is the
latest development in the field of surface improving additives designated TGOA. TGOA is an oil soluble additive
package designed to reduce friction while providing surface protection and improvement. The TGOA additive
package oers superior performance because of its unique action on frictional surfaces.
The TGOA additive package is activated by high specific loads and corresponding temperatures causing a
chemicalphysical reaction. This results in an equalization of surface roughness without creating abrasion.
Therefore, surface roughness is reduced without the loss of surface material.
The results of the TGOA additives can be compared with a rolling process in the micro-range. The surface
roughness is gradually levelled and smoothed. Through smoothing of the working surfaces, the loads are
distributed over increasing areas and the actual load carrying area is enlarged.
If surface roughness peaks redevelop because of shock loads or stop-and-go operation, the TGOA additive
package is automatically reactivated. Surface roughness is again smoothed and lubrication optimized.
Tribol 1100 range has passed the Cincinnati Milacron Thermal Stability Test. This test evaluates copper and steel
corrosion and oxidation stability. Tribol 1100 gear oils are approved as P 74, P 59, and P 35 for the ISO 220, 320,
and 460 grades respectively. These oils exceed minimum requirements according to DIN 51517 Part. 3 for CLP
gear oils
