Product Description
Mobil Vactra™ Ultra 68 is a high precision slideway lubricant specifically designed for linear motion guides, ball screws and slideways of machine tools and metal processing machines. In particular, Mobil Vactra Ultra 68 demonstrates exceptional friction performance and coolant separability.
Features and Benefits
Mobil Vactra™ Ultra 68 has been specifically designed to provide machinery protection and machining accuracy by satisfying the stringent demands of machine tool slideways. Mobil Vactra™ Ultra 68 exhibits excellent lubricity and load-carrying performance contributing significantly to improving the quality of machined parts even at sub-micron level.
Mobil Vactra™ Ultra 68 has been developed with significantly enhanced adhesiveness which prevents lubricants from being washed away from slideways. Lubricant wash-away by coolant can be responsible for abnormal noises, increase in sliding resistance, overload of sliding motors stopping operations and decrease in machining accuracy. Mobil Vactra™ Ultra 68 can help prevent these disturbances, even when high-level washing performance coolants are used.
Mobil Vactra™ Ultra 68 can help minimize formation of adhesive deposits on machine tool slideways due to its excellent compatibility with coolants.
In addition, Mobil Vactra™ Ultra 68 demonstrates outstanding separability from coolants which allows the machine tool to operate with optimal precision and helps maximize the life and performance of coolants.
