Manufacturer's description

Mobil Slideway Oil Ultra 68 is a high-quality slideway lubricant in the ISO VG 68 grade, formulated from premium base stocks and an advanced additive system for the lubrication of linear motion guides, ball screws and slideways of high-precision machine tools and metalworking equipment. The additive package delivers controlled frictional properties on a wide variety of way materials, including steel-on-steel and steel-on-polymer combinations, reducing stick-slip and chatter for smooth, uniform travel and improved machining accuracy. The oil is engineered with strong adhesiveness to resist wash-away by coolant, helping to avoid abnormal noise, increased sliding resistance and loss of machining accuracy, while also providing outstanding separability from aqueous coolants to extend coolant life. Long-term rust and corrosion protection safeguards sliding surfaces exposed to water-based fluids, and the multi-material capability supports product consolidation. It has been tested and optimized for compatibility with Mobil Vactra Oil Numbered Series. ISO VG 68 meets requirements including China GB 11118.1-2011 L-HG, DIN 51502:1990-08 CGLP, ISO L-GA and L-GB (ISO 6743-13:2002) and Fives Cincinnati P-47. Typical properties include a kinematic viscosity of 70.5 mm2/s at 40°C, a flash point of 245°C and a pour point of -12°C.

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.
