Product Description
Castrol Tribol GR 4020 PD Range (previously called Tribol 4020 Range) 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 GR 4020 PD greases exceed conventional complex greases due to the advanced TGOA additive technology. Under relatively high specific loads and related temperatures, this technology promotes a nondestructive 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 optimized.
Application:
Tribol GR 4020 PD greases were formulated as multi-service lubricants for heavy duty applications of plain and antifriction 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 GR4020 PD 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.
