Product description
Klübersynth BH 72-422 is a synthetic high-temperature grease with a patented formulation based on ester and perfluorinated polyether (PFPE) oils. The outstanding characteristics of this innovative lubricant are good oil retention when subjected to thermal load and excellent thermal stability, enabling the product to withstand service temperatures above approx. 150 °C. Many applications do not require pure PFPE/PTFE greases and for that reason Klübersynth BH 72-422 closes the "operating temperature gap" between conventional products based on hydrocarbon oils and pure PFPE/PTFE lubricants. However, a permanent operating temperature of 180 °C should not be exceeded in highly loaded roller bearings with a C/P load ratio of < 8.

Benefits for your application

Longer service life compared to conventional greases based on ester oils
- due to the extremely high ageing stability of the PFPE oil contained in the lubricant
Lower lubricant costs compared to perfluorinated polyether greases
- due to patented hybrid grease formulation
