Examples of application
- High loaded spur, bevel, and worm gears of rolling mills, crushers, mills, calenders, cranes, conveyors and open cast mining equipment
- Oil-lubricated roller bearings of vertical roller mills, roller presses, crushers, calenders
- Gears with continuous operating temperatures above100 °C
- Gearboxes and oil circulation systems in the paper and textile industry
- Machines and equipment in deep freezing plants
Properties
- Excellent protection against wear and seizure
- Very high micro-pitting resistance
- Very high oxidation and aging resistance allowing extended oil change intervals
- Very high viscosity index and therefore low change in viscosity over a wide service temperature range
- Excellent corrosion protection
- Very high shear resistance
- Good demulsifying properties
- Low foaming tendency
- Easily filterable even in the presence of water
- Reduces the coefficient of friction and therefore enables a reduction in service temperature and friction losses
- Exceeds the requirements for lubricating oils CLP according to DIN 51517-3, ANSI/AGMA 9005-F16 as well as CKD and CKSMP according to ISO 12925-1
- Compatible with mineral oil resistant seal materials and machine paints
- Miscible with mineral oil
