I. Description of grease Shell Alvania EP
- Shell Alvania EP Grease D is a long-life railroad grease with extreme pressure additives to provide higher load carrying capacity. This grease meets the requirements of AAR M-942- (Revised 1992) and NSW SRA L343-84.
II. Performance features of Shell Alvania EP
- • Extended Bearing Life
- The extreme pressure additives in Shell Alvania EP Grease D provide higher load carrying capacity, reduce bearing wear and bearing failures.
- • Water and Corrosion Protection
- The lithium/calcium mixed soap thickener gives the grease superior water resistance and is combined with anti-corrosion additives to further enhance protection of bearing surfaces.
- • Prolonged Grease Service Life
- Shell Alvania EP Grease D resists hardening or softening due to its excellent mechanical stability and therefore lubricates for hundreds of thousands of kilometres in railroad bearings without the need for relubrication.
- • Simplified Inventory
- The overall superior performance of Shell Alvania EP Grease D means it can be used to rationalise grease stocks to one railroad axle bearing grease for all bearing types.
III. Applications of Shell Alvania EP
- The Association of American Railways (AAR) have developed a grease specification AAR M942 (Revised 1992), designed to eliminate field lubrication, so that they only have to grease bearings when rail cars are brought to the shop for wheel repair.
- This practice requires a
- grease capable of performing in the bearings for hundreds of thousands of kilometres or up to 10 years, without the need for re-lubrication.
- Shell Alvania EP Grease D is specifically designed as a long life railway bearing grease meeting the above AAR requirements.
