Areas of application
- Grease lubrication of friction and rolling bearings in the high-temperature range up to 280°C
- Lubrication of tunnel kiln cars, baking, burn-in and drying furnaces, hot gas units, reaction vessels, boiler plants, roller and conveyor rollers in continuous furnaces, etc.
- Use at bearing points under influence of chemicals
- Lubrication of bearings under influence of fuel
Advantages and benefits
- Absolutely resistant to water and steam

Applications
Thorough cleaning of the bearings from other lubricants, for example with OKS 2610/OKS 2611 universal cleaning agent is imperative. Subsequently blow out with dry air. Before filling for first time, remove anti-corrosion agent. Fill the bearing such that all functional surfaces are certain of being greased. Fill bearings running slowly completely, fill high-speed bearings (DN value > 150,000) only up to about 2/3 of the free space inside the bearing. The bearing and machine manufacturer's instructions should be observed. Specify the relubrication frequency and quantity on the basis of the conditions of use. If old grease cannot be removed, restrict the quantity of grease so as to avoid overlubricating the bearing. Only mix with suitable lubricants.
