Mobil Slideway Oil Ultra 68
Mobil Slideway Oil Ultra 68 is a high-quality slideway lubricant specifically designed for the lubrication of linear motion guides, ball screws and slideways in high precision machine tools and metal processing equipment. It is formulated using high-quality base oils and an advanced additive system to provide controlled friction characteristics, compatibility with aqueous metalworking fluids and effective corrosion protection for machine components. These properties help improve machining accuracy and overall equipment performance.
One of the key advantages of Mobil Slideway Oil Ultra 68 is its excellent friction control performance. The unique additive system provides consistent friction characteristics across a wide range of way materials including steel-on-steel and steel-on-polymer combinations. This helps reduce stick-slip and chatter, allowing smooth and uniform motion at design travel speeds, improving machining accuracy and surface finish.
Mobil Slideway Oil Ultra 68 also provides strong adhesiveness, helping the lubricant remain on slideway surfaces even in the presence of coolant washdown. This helps prevent abnormal noise, increased sliding resistance and loss of positioning accuracy. The lubricant also demonstrates excellent load-carrying performance, supporting improved machining quality and extended tool life.
Another important benefit is its outstanding separability from aqueous coolants. Mobil Slideway Oil Ultra 68 separates readily from many metalworking fluids, helping maintain coolant performance and extending coolant life. The lubricant also provides long-term rust and corrosion protection, helping protect slideway surfaces in wet environments.
Mobil Slideway Oil Ultra 68 is recommended for lubrication of machine tool slideway systems and is suitable for combinations of cast iron, steel and non-metallic way materials. It may be applied by hand, forced-feed lubricator or circulation systems. The product is suitable for horizontal slideways on small to medium size machine tools, ball screws, linear guides, headstocks and translating screws. It may also be used in moderate duty hydraulic applications.
Physical characteristics include ISO VG 68 viscosity grade with a kinematic viscosity of approximately 70.5 mm²/s at 40°C. Mobil Slideway Oil Ultra 68 has a flash point of approximately 245°C and a pour point of approximately −12°C. The product also provides FZG scuffing performance of stage 12 and strong corrosion protection, supporting reliable performance in precision slideway lubrication applications.
