Klubersynth BH 72-422 is a synthetic hightemperature 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 short-term temperature peaks well above a service temperature of approx. 150°C, which is typical of this type of application.
Klubersynth BH 72-422 fills the "operating temperature gap" between conventional products based on hydrocarbon oils and pure PFPE lubricants (see diagramme overleaf). In many applications it is therefore possible to do without pure PFPE lubricants. However, a permanent operating temperature of 180°C should not be exceeded in highly loaded roller bearings.
Applications: Klubersynth BH 72-422 can be used for lowspeed bearings and guides subject to high permanent temperatures, e.g. in calenders and conveyors.
Klubersynth BH 72-422 is listed in the lubrication charts of the leading manufacturers in the wood board, rubber and plastics as well as textile industries.
Application notes
Klubersynth BH 72-422 can be used in rolling bearings without having to remove the anticorrosion film first. The product is even miscible with pure PFPE/PTFE greases. However, to ensure optimum performance, we recommend to always clean surfaces thoroughly before applying the Klubersynth BH 72-422 for the first time.
Klubersynth BH 72-422 can be removed using an organic solvent. Compatibility with the material contact should be checked especially prior to series application. Minimum shelf life The minimum shelf life is approx. 36 months if the product is stored in its unopened original container in a dry, frost-free place.
