Description
Klüberalfa BHR 53-402 High-temperature long-term lubricating grease NLGI 2 | N° 0900700608
- 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.
- Temperature range: -40°C to +260°C
- Volume: 800g cartridge
- Also available in: 1 kg can, 10kg bucket
Benefits for your 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
Applications
- 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.
Application notes
- Klüberalfa BHR 53-402 can be applied with a grease metering gun or automatic metering devices for small quantities.
- Anticorrosion agents have to be removed from the friction points prior to initial lubrication to ensure optimum lubricant adhesion.
- Klüberalfa BHR 53-402 can be mixed with lubricants based on PFPE.
- Klüberalfa BHR 53-402 (e.g. used grease in rolling bearings) can be removed with water-miscible neutral cleaning agents.
