The Castrol Magna™ SW B Range (previously called Magnaglide™ B grades) are premium slideway lubricants for machine tools.
They are based on highly refined mineral oils and additives to give controlled frictional characteristics in guideway sliding conditions.
The Magna SW B oils are recommended for the high performance lubrication of slideways on machine tools. They have excellent frictional characteristics, high adhesivity, and high film strength, so that they can be used in conditions of high loads and low sliding speeds on both vertical and horizontal guideways.
Furthermore, they can be used for lead screw and nut systems, gears of feed mechanisms and oil lubricated milling heads. The Magna SW B oils meet the criteria of the Schmidt-Coburg friction and demulsibility tests, thus the range has excellent water wash off characteristics.
