    You are looking for a rolling bearing grease offering good corrosion and wear protection for use also at high temperatures?

    Klüberalfa BHR 53-402 is a high-temperature long-term grease based on perfluorinated polyether oils. Due to its special thickener, it can be removed from components without the use of fluorinecontaining solvents.

    Klüberalfa BHR 53-402 is neutral towards plastics and elastomers and can thus be used with a variety of materials.

    Preferred applications are in rolling bearings with lifetime or longterm lubrication which are subject to very high temperatures:

    • conveyor systems, e.g. load, guide or return rollers and crossbar plain bearings
    • ceramics or brick manufacturing, e.g. bearings of kiln carts (carrying wheels)
    • electric motors, fans

    General behaviour towards elastomers and plastics Greases based on perfluorinated polyether oils are generally regarded as neutral towards elastomers and plastics (possible exception: highly fluorinated rubber). Nevertheless we recommend testing compatibility with the material to be used, especially prior to series application.

    Higher equipment availability and reduced maintenance at very high operating temperatures up to 260 °C

    • due to good corrosion protection
    • due to improved wear protection

    Cost-efficient and eco-friendly product

    • due to lifetime lubrication
    • as equipment can be cleaned without use of fluorine-containing solvent
