Klübersynth BH 72-422 High-temperature lubricating grease for low-speed bearings, patented hypbrid greases concept for the long - term lubrications of slow, large rolling brearings, plain bearings and sideways.
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.
