    High-temperature lubricating greases.

    STABUTHERM GH 461 and STABUTHERM GH 462 are hightemperature lubricating greases based on mineral oil and polyurea. They have a wide service temperature range and can be applied in rolling bearings up to 180°C. If the lubricant is used in central lubrication systems, operating temperatures up to 200°C are possible. STABUTHERM GH 461 and STABUTHERM GH 462 feature highly effective anti-wear properties. The greases are very adhesive and resistant to water both under static and dynamic load. STABUTHERM GH 461 and STABUTHERM GH 462 are resistant to oxidation and provide reliable protection against corrosion.

    STABUTHERM GH 461 and STABUTHERM GH 462 are particularly suitable for applications in smelting works and rolling mills, especially for high-temperature lubrication points supplied through a central lubrication system, e.g.

    • drive rollers in continuous casting installations (slabs and billets)
    • conveyor rollers in continuous furnaces

    Lubricants for such applications must meet extremely high requirements regarding operating temperature, scaling, water and ensuing corrosion.

    STABUTHERM GH 461 and STABUTHERM GH 462 are also suitable for other high-temperature applications, such as:

    • annealing furnaces, drying stoves
    • plain bearings in foundry cranes
    • hot rolls in cardboard manufacturing plants
    • road tarmacking machines
    • shut-off gates in bulk material installations
    • cooling beds, conveyor systems
    • rotary kilns
    • machines and installations in the automotive, beverage, glass
    • and ceramics industries

    STABUTHERM GH 461 and STABUTHERM GH 462 can be pumped through all common types of lubrication systems. Pipe friction values were determined in order to assess the pumpability in central lubrication systems.

    The results obtained at different temperatures are illustrated in diagrams 1 and 2 on pages 3 and 4.

    Diagram 1 shows the resistance to pumping per meter of pipe with a diameter of 7 mm; diagram 2 shows the values of a pipe with a diameter of 16 mm. The pipe friction values were measured with a Shell DELIMON rheometer system.

    Reduction of lubricant costs due to

    • lower consumption
    • reduced waste water disposal costs due to excellent water resistance

    Longer component life and trouble-free operation due to

    • good wear protection, good load- carrying capacity even at high temperatures
    • excellent corrosion protection

    Proven pumpability and metering in central lubrication systems
