High-temperature long-term greases.
Klübertemp HM greases are long-term lubricating greases based on perfluoropolyether oil and PTFE which has been specifically designed for high-temperature lubrication. Owing to the base oil viscosity and the high load-carrying capacity, Klübertemp HM greases are particularly suitable for the initial and relubrication of medium-speed rolling bearings subject to high temperatures and loads.
Klübertemp HM greases have proven effective for lubrication points requiring regular maintenance at temperatures up to 260 °C. Klübertemp HM greases contribute to reliable machine operation in many industries as they are available in three consistency grades which make them suitable for a wide range of applications.
Typical applications are:
Klübertemp HM greases are listed in the maintenance and lubrication charts of many leading manufacturers.
Compatibility with plastics and elastomers
Lubricating greases based on fluorinated polyether oils and PTFE are generally regarded as neutral towards elastomers and plastics (with the exception of perfluorinated rubber). Nevertheless compatibility with the materials should be tested, especially prior to series application.
For optimum lubrication results, we recommend cleaning the friction points first with white spirit 180/210 and then with Klüberalfa XZ 3-1. For initial lubrication, the friction points must be clean and bright (i.e. free from oil, grease or perspiration) and free from contaminants. The various technical sales departments at Klüber Lubrication may be contacted at any time to ensure optimum results with this special lubricating grease.
