OKS 425 – Synthetic Long-Life Grease

Lubrication of roller and plain bearings as well as of threaded spindles, gearwheels, worms and similar components Lubrication of spindle bearings in machine tools Advantages and benefits Allows high machine service lives due to low-wear operation and low lubrication frequencies Outstanding resistance in a wide temperature range, at high stresses and surface slide speeds as well as at vibrations Resistant to cold and hot water Excellent wear protection For highest effectiveness carefully clean the lubrication point, for example with OKS 2610/OKS 2611 universal cleaner. Before filling a bearing for first time, remove anti-corrosion agent. Fill the bearing such that all functional surfaces are certain of being greased. Fill normal bearings up to about 1/3 of the free space inside the bearing, high-speed bearings (DN value above 400,000) up to about 1/4. Low-speed bearings (DN value below 50,000) and their housings should be filled completely.

Lubrication of temperature-stressed machine parts, e.g. rolling bearings, friction bearings, slideways, chains, rollers or moving parts in hot forming, heat treatment or drying Dry lubrication, e.g. of kiln and rack-truck bearings, bearings of pouring ladles, converters or hot-air blowers at temperatures over 250°C Lubrication of plastic and rubber at normal temperature when the materials concerned are not resistant to mineral oil Advantages and benefits Highly effective due to the strong affinity of the MoS₂ for metals Extremely low friction at highest loading capability Broad range of applications at temperatures up to 200°C as paste, over 200°C to 450°C as dry lubricant Resistant to water, fuels and lubricants, chemicals and hydraulic fluids For best adhesion, clean the threads and sliding surfaces from dirt and other lubricants. Best way is to clean mechanically first and then with OKS 2610 or OKS 2611 universal cleaner.

Assembly lubrication of screw connections of high-strength steel subject to high temperatures, corrosive influences in chemically aggressive environments, e.g. on gas and steam turbines in power plants, combustion engines, threads on pipe fittings, flange joints and fittings in superheated steam lines, exhaust pipe and combustion chamber screwed connections etc. Parting lubrication of materials with a tendency to seize up, e.g. V2A, V4A and high-temperature steels Advantages and benefits Excellently suited for preventing seizing and binding Highly effective against corrosion affects Free of lead compounds, sulphides, chlorides and fluorides For best adhesion, clean the threads and sliding surfaces from dirt and other lubricants. Best way is to clean mechanically first and then with OKS 2610 or OKS 2611 universal cleaner. Apply paste evenly in sufficient amount onto head/nut support and thread or onto the sliding areas with brush, spatula, etc.

Grease lubrication of friction and rolling bearings in the high-temperature range up to 300°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 Resistant to solvents, for example benzene, benzol, acetone, trichloroethylene and against inorganic acids, for example sulphuric acid, hydrochloric acid and nitric acid as well as stearic acids, alcohols and halogens Broad range of applications above the temperature limits of other lubricating greases Excellent wear protection Reduced maintenance and lubricant costs due to possible lifetime lubrication Excellent plastic and elastomer compatibility
