Typical characteristics

Manufacturer's description

Mobil Vactra Slideway lubricants are high-quality products specifically designed for lubricating linear motion guides, ball screws and slideways on high-precision machine tools and metal-processing machines. Formulated from high-quality base stocks and an advanced additive system, they deliver controlled frictional properties for high-precision machining, compatibility with aqueous metalworking fluids, and corrosion protection of parts and equipment. Their unique additive package gives excellent frictional characteristics across steel-on-steel and steel-on-polymer way materials, reducing stick-slip and chatter for smooth, uniform motion. Available in ISO VG 68 and 220 grades, Mobil Vactra Slideway is recommended for horizontal slideways on small-to-medium precision machine tools, circulating application in larger machines, moderate-duty hydraulic use, and lubrication of ball screws, linear guides, headstocks and translating screws. Its adhesiveness resists coolant wash-away, while outstanding separability from aqueous coolants helps extend coolant life and machine precision. Mobil Vactra Slideway 68 is the ISO VG 68 grade, with a viscosity of 70.5 mm²/s at 40°C, a pour point of -12°C and a flash point of 245°C. The series sheet recommends this grade for applications requiring Fives Cincinnati P-47. It meets China GB 11118.1-2011 L-HG, DIN 51502:1990-08 CGLP and ISO 6743-13 L-GA/L-GB classifications, and has been tested for compatibility with the Mobil Vactra Oil Numbered Series.

Applications

• Recommended for the lubrication of machine-tool slideway systems, designed for use with combinations of cast iron, steel and non-metallic way materials.
• May be applied by hand, forced-feed lubricator, or in flood application by circulation system.
• Recommended for horizontal slideways on small to medium-size machine tools in high-precision applications; also suitable for circulating application in large machines and as a moderate-duty hydraulic fluid.
• Can be used for lubrication of ball screws, linear guides, headstocks and translating screws.
• Recommended for applications where oil contamination of aqueous coolants shortens coolant batch life.

Performance & benefits

• Provide excellent machinery protection and machining accuracy, satisfying the stringent demands of machine-tool slideways.
• Excellent lubricity and load-carrying performance contribute significantly to improving the quality of machined parts, even at sub-micron level.
• Adhesiveness prevents lubricant from being washed away from slideways, avoiding abnormal noises, increased sliding resistance, motor overload and decreased machining accuracy caused by coolant wash-away.
• Outstanding separability from coolants allows the machine tool to operate with high precision and helps maximize the life and performance of coolants.
• Tested and optimized for compatibility with the Mobil Vactra Oil Numbered Series.
• Controlled frictional characteristics reduce stick-slip and improve machining accuracy for high-precision applications, even at sub-micron level.
• Adhesiveness prevents washing of lubricant out of critical surfaces.
• Water and aqueous-coolant separability helps improve the life and performance of many aqueous coolants.
• Long-term rust and corrosion protection helps reduce the deterioration of sliding surfaces in the presence of water and aqueous coolants.
• Multi-material capability suits a wide range of slideway material combinations, allowing for product consolidation.
