Description
Klüberalfa BF 83-102 Lubricating grease for high temperatures and speeds NSF H1 | N° 090127
- Klüberalfa lubricants based on perfluorinated polyether (PFPE) have been developed for specific applications where optimum performance under lifetime lubrication conditions is required.
- Klüberalfa BF 83-102 has been designed to ensure long service life of rolling bearings subject to high speeds and very high permanent temperatures.
- The calculated speed factor sets new standards in the formulation of high-temperature PFPE greases with PTFE thickeners.
- Temperature range: -50°C to +200°C
- Volume: 1 kg can
Benefits for your application
- Allows new applications in high-speed bearings lubricated with grease
- due to better thermal stability than conventional high-speed greases
- due to better speed characteristics than conventional PFPE/PTFE high-temperature greases
- due to NSF-H1 registration
Applications
- Klüberalfa BF 83-102 is suitable, e.g. for fan bearings in turbochargers, small turbines, generator bearings etc.
- Even at low temperatures the consistency of Klüberalfa BF 83-102 is low enough for use in low-torque drives.
- Klüberalfa BF 83-102 is registered as NSF H1 and complies with FDA 21 CFR § 178.3570.
- Compatibility with plastics and elastomers Lubricating greases based on perfluorinated polyether oils (PFPE) are generally regarded as neutral towards standard elastomers and plastics and therefore allow the use of a wide range of different materials in construction (exception: fluorinated rubber).
- Nevertheless compatibility with the materials should be tested, especially prior to series application.
Application notes
- For optimum lubrication results, we recommend cleaning the friction point with white spirit 180/210 and then with Klüberalfa XZ 3-1 prior to initial lubrication.
- The friction point has to be bright (i.e. free of oil, grease and perspiration) and free of contamination particles.
- To optimise service life, please contact our technical sales staff.
