Description Castrol Tribol™ 3020 is a range of greases formulated from highly refined petroleum base oils, a lithium thickener, and Tribol Grease Oil Additive (TGOA).. The TGOA additive package outperforms all other EP and antiwear additives because of its unique action on Frictional surfaces. The base oils are high-viscosity mineral oils forming a stable lubricant film to withstand high continuous loads, shock loads and vibrations. 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. The results of the TGOA additives can be compared with a rolling process in the micro-range. The surface roughnesses are gradually leveled and smoothed. Through smoothing of the working surfaces, the loads are distributed over increasing areas and the actual load carrying areas are enlarged. During the running-in process, the TGOA additive package creates an optimum of smooth contact surfaces. If, because of shock loads, or stop-and-go operation, surface roughness peaks redevelop, the TGOA additives are automatically reactivated. Surface roughness is again equalized and lubrication optimized. Corrosion and oxidation inhibitors help maximize effective rust protection and long life of the grease.Tribol 3020 meet NLGI consistency grades commonly available for these types of lubricants. Application Typical applications for Castrol Tribol 3020 greases are non-oil-tight gear units, rolling and sliding bearings, bushings, slides and general lubrication designed for fluid-grease lubrication. Applications include large slow-speed bearings where the Castrol Tribol 3020 greases provide for a sufficient lubricating film due to theirhigh base oil viscosity. Operating temperatures can range from –40°C to +120°C depending on NLGI grades. Advantages Compared to conventional greases provides the following advantages: Excellent pumpability in central lubrication systems. Repairing of damaged friction surfaces (roughness) due to the TGOA additives. Extended lubrication interval. Reduced wear and noise. Lowering of the operating temperatures. Low downtime thus reducing maintenance and repair costs. Due to their excellent adhesion, these greases offer an optimum sealing effect.
