Castrol TribolTM 4020 greases are formulated from highly-refined petroleum base oils, a lithium complex thickener, and Tribol Grease Oil Additive (TGOA), the latest advancement in the field of friction reducing and surface improving additive technology. These multi-service greases are designed to extend the service life of bearings in heavy-duty and elevated temperature applications.
The load-carrying, anti-wear, and friction reducing capabilities of Tribol 4020 greases exceed conventional complex greases due to the advanced TGOA additive technology. Under relatively high specific loads and related temperatures, this technology promotes a non-destructive smoothing of surface roughness in the micro-range. This smoothing effect reduces friction and leads to an increase of the actual load-bearing surface.
If surface roughness peaks redevelop because of shock loads or stop-and-go operation, the TGOA additive package automatically reactivates. Surface roughness is again smoothed and lubrication optimized.
Advantages
Advanced TGOA additive technology – multiple benefits including reduced friction, temperatures and noise, increased load carrying ability, and superior surface protection.
Excellent water resistance – the coating film stays on the surface even in the presence of water.
Excellent mechanical stability and adhesion – the grease keeps its consistency in service ensuring long term protection and reduced consumption as film stays between lubricated surfaces.
Superior oxidation resistance – prevents corrosive activity on bearings in aggressive environments.
Formulated to address environmental concerns – it is free of antimony, barium, lead and zinc.
Applications: Tribol 4020 greases were formulated as multi-service lubricants for heavy-duty applications of plain and anti-friction bearings under medium-to-high loads. The TGOA additives are very effective in protecting the machined surfaces of bearings during the critical ‘running-in’ period. Good bearing surfaces are essential for long bearing life.
Tribol 4020 is commonly used as a plant-wide lubricant in the automotive industry as well as industries where the preference is for a high-performance non-dark grease.
