Castrol MA 6040/460-1 1/2
CASTROL MOLUB-ALLOY™ 6040 greases are extreme pressure (EP) multi-service lubricants designed to give outstanding performance across a wide variety of applications, suitable for use in either journal or antifriction bearings in the most demanding industrial applications under extreme environmental conditions. Manufactured from the highest quality petroleum oil and thickened with a unique calcium complex sulfonate unsurpassed for mechanical shear stability, MOLUB-ALLOY 6040 greases are compounded with chemical additives for EP characteristics and select MOLUB-ALLOY lubricating additives for thin-film, high-pressure anti-wear protection, and are inhibited against high temperature oxidation and corrosion. Corrosion and oxidation inhibitors maximise effective rust protection and long grease life. Operating temperature range: -40°C to +140°C. Typical applications for the 6040/460-1.5 grade are bearings under heavy water contamination.
KEY FEATURES
| •Load carrying and anti-wear capabilities exceed conventional complex greases |
| •Offers excellent oxidation resistance and resists washing out, even under adverse water contamination; designed to work with aggressive process waters |
| •Reduced friction is most evident under boundary and mixed-film lubrication conditions, particularly where frequent start-up, slow speeds, or high and unexpected heavy loads are encountered |
| •Overall savings result from less labour and downtime, and smoother, more efficient operation with longer parts life and extended lubrication cycles |
