    Klüberlub PHB 71-461 is a special high-temperature lubricating grease based on mineral oil and polyurea. It is suitable for a wide service temperature range and can be used up to 180°C under continuous relubrication conditions. Klüberlub PHB 71-461 may be applied via centralized lubrication equipment.

    Klüberlub PHB 71-461 incorporates special EP additives ensuring good wear protection under high load conditions.

    Klüberlub PHB 71-461 provides reliable corrosion resistance in a wet environment as well as good adhesion and oxidation stability. Its blue colour allows simple identification and assessment of general grease condition whilst helping eliminate the possibility of mixing with foreign greases.

    Klüberlub PHB 71-461 was especially designed for high temperature applications in continuous fibreboard presses.

    The grease is used for the lubrication of drum bearings, guide rollers, shaft bearings and plain bearings in Siempelkamp and Dieffenbacher fibreboard manufacturing equipment.

    Further applications include high-temperature lubrication points subject to high loads, moisture and temperature variations such as those found in:

    • conveyors
    • dryers
    • steel mills.

    Klüberlub PHB 71-461 can be applied via most commercially available centralized lubrication systems. The product should be continuously purged through small bore pipes, which are exposed to high pressure and temperature.

    • High-temperature lubricating grease for rolling bearings up to 180°C
    • For low to medium speeds
    • Good pumpability in most commercially available lubrication systems
    • Blue colour, hence less risk of confusion / mixing etc.
    • Good wear protection and high load-carrying capacity
    • Good corrosion protection
    • Resistant to water
