Description:

Shell GadusRail S3 AAR AL is a long life grease specifically formulated to meet the Association of American Railroads (AAR) Specification M-942-2012. It features a lithium/calcium mixed soap thickener in an all HVI paraffinic mineral base oil system combined with a high performance additive package. Shell GadusRail S3 AAR AL is also formulated to meet Timken’s standard for Dynamic Mechnical Stability. It gives exceptional mechanical stability, even at elevated temperatures.

The high quality additive system is designed specifically for the grease to be used in railroad axle journal roller bearings, which are designed not to be lubricated in the field, including those in the newer, more heavily loaded double stacked container cars. The additive system also promotes superior protection against oxidation.

Performance, Features and Benefits:

•Excellent mechanical stability over a wide range of temperatures. 

•Superior protection against oxidation. 

•Endurance at elevated temperatures for long periods. 

•Passing performance in the more severe Roll Stability Test run at an elevated temperature of 1800F for 96 hours. 

•Passing performance in the Timken Dynamic Mechanical Stability test. 

•AAR approved. 

Application:

•Mainly railroad axle journal bearings. 

•Bearings subjected to heavy loads without the need for frequent relubrication or concern with mechanical stability breakdown.
