Klüber Lubrication recently introduced a new rolling bearing grease for high loads and temperatures. Klübertherm HB 88-182 is a long-term grease with corrosion and wear protection for rolling bearings subject to high loads and medium speeds at temperatures up to 356 degrees F (180 degrees C).
The grease is fully synthetic and based on a thermally stable base oil, polytetrafluoroethylene (PTFE) thickener and special additives. It is formulated to help close the performance gap between greases based on perfluorinated polyether (PFPE) oils, which are suitable for high temperatures, and conventional high-temperature greases, which soon reach their limit when exposed to high thermal loads.
Klübertherm HB 88-182 is also designed to optimize lubrication intervals and protect components against premature failure while providing better degradability in the environment than PFPE-based products.
The grease's density is only about half that of PFPE-based lubricants, enabling cost savings. Its lower shear viscosity also offers the potential for energy savings.
Klübertherm HB 88-182 can be used in rolling bearing applications in corrugating machines, rotary unions, generator bearings, conveyors, hydraulic couplings, smoke extractor motors and ceramic ovens, as well as cylindrical roller bearings with a high percentage of sliding friction and sealing systems in the automotive industry.
