CASTROL Tribol 4020

Description

Castrol Tribol™ 4020/220-2 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 4020/220-2 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.

Applications

Tribol 4020/220-2 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 4020/220-2 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.
