Castrol Tribol SW MWO Range (previously called Tribol MWO LS) way oils are used for the lubrication of machinetool slides and ways. Tribol SW MWO 20 and 40 are ISO Viscosity Grades 68 and 220, respectively. These unique wayoils are intended for use where solid lubricants cannot be used for cosmetic or other reasons. Tribol SW MWO way oilsoffer excellent thin-film wear protection due to a proprietary blend of anti-wear, extreme pressure (EP) and frictionmodifyingagents which perform synergistically in combination. When subjected to the extreme pressure of contactingasperties these additives convert to low-shear compounds on working surfaces, lubricating much like solid-filmlubricants. Because the additives in Tribol SW MWO way oils are fully dissolved but act like solid lubricants in service,the products are designated "LS" for "Liquid Solids." The high quality base oils in Tribol SW MWO way oils are selectedfor their ability to maintain strong film integrity even under great stress. Additional compounding with select polymersadds both adhesive and cohesive characteristics to these products. Tribol SW MWO way oils are not corrosive to ferrousor non-ferrous metals and rust and oxidation inhibiting characteristics are maximized to afford effective rust protectionand long life of the oil. Tribol SW MWO way oils are "low phenol" products, typically containing less than 2 ppm ofphenolic compounds.
Tribol SW MWO way oils are recommended where the use of lubricating solids may be restricted due to manufacturer'srequirements, very fine filtration, or concerns about solids contaminating the manufacturing process. They are alsosuitable for lubricating many components of machine tools, including slides and ways, plain and antifriction bearings,translating screws, headstock gears, and some circulating systems.Tribol SW MWO way oils are especially useful in applications where non-drip characteristics are desirable to reduce oilloss or control "fly-off" from cams, eccentrics, conveyors, press shaft bearings, and in worn and older machines withexpanded clearances. Other important uses for Tribol SW MWO way oils include the lubrication of chains and wire ropeswhere good adhesion and tackiness are needed, particularly where there is the potential for heavy condensation orwaterwash.Tribol SW MWO way oils are not intended for use in hydraulic systems or some circulating systems that serve both waysand critical hydraulics.
