Description
Castrol Tribol™ 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 optimised.
Application
-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.
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
Additional Information
In order to minimise potential incompatibilities when converting to a new grease, all previous lubricant should be removed
as much as possible prior to operation. During initial operation, re-lubrication intervals should be monitored closely to
ensure all previous lubricant is purged.
