Castrol Tribol™ GR 3020/1000 PD (previously called Tribol 3020/1000) 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 Extreme Pressure (EP) and Anti-Wear (AW) 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 chemical physical reaction. This results in an equalisation 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. In smoothing 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 equalised and lubrication optimised. Corrosion and oxidation inhibitors help maximise effective rust protection and long life of the grease.
The Tribol GR 3020/1000 PD Range contains NLGI consistency grades commonly available for these types of lubricants.
Applications include large slow-speed bearings where the Tribol 3020/1000 PD greases provide a sufficient lubricating film due to their high base oil viscosity
Typical applications for Tribol GR 3020/1000 PD fluid greases (NLGI 0,00,000) are non-oil-tight gear units, rolling and sliding bearings, bushings, slides and general lubrication designed for fluid-grease lubrication
Tribol GR 3020/1000 PD grease (NLGI 1 &2) can be used for roller and sliding bearings, spindles, power train couplings (with exception to high speed precision couplings), carriages, cams and common grease points.
They're commonly used in the steel, mineral compound, construction and mining industry.
Operating temperatures range from -40°C to +120°C/ -40°F and +248°F
