Castrol Tribol
® MWO LS Way Oils
Description
Castrol Tribol MWO LS Way Oils are for the lubrication of machine tool slides and ways.. MWO 20LS and 40LS are ISO
Viscosity Grades ISO VG 68 and 200, respectively. These unique Way Oils are intended for use where solid lubricants
cannot be used for cosmetic or other reasons.
Tribol MWO LS Way Oils offer excellent thin-film wear protection because of a proprietary blend of antiwear, extreme
pressure (EP), and friction-modifying agents which perform synergistically in combination. These agents are fully
dissolved in oil. When subjected to the extreme pressure of contacting asperties (microscopic high spots), these
additives convert to low-shear compounds on working surfaces, lubricating much like solid-film lubricants.
Because the additives in Tribol MWO LS 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 MWO LS Way Oils were selected for their ability to maintain strong film integrity even
under great stress. Additional compounding with select polymers adds both adhesive and cohesive characteristics to
these products.
Tribol MWO LS Way Oils are not corrosive to ferrous or non-ferrous metals and rust and oxidation inhibiting
characteristics are maximized to afford effective rust protection and long life of the oil.
Tribol MWO LS Way Oils are "low phenol" products, typically containing less than 2 ppm of phenolic compounds.
Application
Tribol MWO LS Way Oils are recommended where the use of lubricating solids may be restricted due to manufacturer's
requirements, very fine filtration, or concern about solids contaminating the manufacturing process. Tribol MWO LS Way
Oils are also suitable for many components of machine tools, including slides and ways, plain and antifriction bearings,
translating screws, headstock gears, and some circulating systems (see Notes).
Tribol MWO LS Way Oils are especially useful in applications where non-drip characteristics are desirable to reduce oil
loss or control "Fly-off" from cams, eccentrics, conveyors, press shaft bearings, and in worn and older machines with
expanded clearances.
Other important uses for Tribol MWO LS Way Oils include the lubrication of chains and wire ropes where good adhesion
and tackiness are needed. These characteristics are especially needed where there is potential for heavy condensation,
or even water wash.
Advantages
· Tribol MWO LS Way Oils special formulation is most effective toward the elimination of "stick-slip" and "chatter" on
all ways, vertical and horizontal.
· Their clear appearance and non-drip nature can reduce the soilage of production and housekeeping problems as
well.
