Castrol TRIBOL GR 4020/220-1PD 190 KG
Castrol Tribol GR 4020/220-1 PD (previously called Tribol 4020) is a high performance bearing grease. It is 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. This multi-service grease is designed to extend the service life of bearings in heavy duty and elevated temperature applications. The load-carrying, anti-wear, and friction reducing capabilities exceed conventional complex greases due to the advanced TGOA additive technology, which under relatively high specific loads and related temperatures promotes a non-destructive smoothing of surface roughness in the micro-range. If surface roughness peaks redevelop because of shock loads or stop-and-go operation, the TGOA additive package automatically reactivates.

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. |
Application
| •Multi-service lubricant for heavy duty applications of plain and anti-friction bearings under medium to high loads. |
| •Protecting the machined surfaces of bearings during the critical 'running-in' period. |
| •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. |
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. |
| •This product was previously called Tribol 4020. The name was changed in 2015. |
