Kl?ber Lubrication, a worldwide manufacturer of specialty lubricants, has introduced Klübertherm HB 88-182 for the long-term lubrication of rolling bearings. This pioneering lubricating grease offers excellent high-temperature properties and can be used for low loads combined with high speeds and high loads combined with low speeds. It is fully synthetic and based on a thermally stable base oil, polytetrafluoroethylene (PTFE) thickener and special additives.
Klübertherm HB 88-182 protects more effectively against friction and wear than other high-temperature greases, proven in the field and on FE8 and FE9 rolling bearing testers.
“Klübertherm HB 88-182 closes the performance gap between greases based on perfluorinated polyether (PFPE) oils, which are suitable for high temperature and, for example, conventional high-temperature greases which soon reach their limit when exposed to high thermal loads,” said Steve Mazzola, director, engineering and technical services, Klüber Lubrication North America L.P. “With Klübertherm HB 88-182, we developed an economically efficient lubricant showing excellent high-temperature properties.”
Klübertherm HB 88-182 protects more effectively against friction and wear than other high-temperature greases, proven in the field and on FE8 and FE9 rolling bearing testers. At high temperatures, the new grease does not form residues like high-temperature greases containing a polyurea thickener. Klübertherm HB 88-182 is resistant to hydrolysis and protects components effectively against corrosion at high temperatures and in humid environments. It shows excellent compatibility with elastomer and thermoplastic components and seals. The grease stays soft and retains lubricity even after 500 hours at 180°C in the FE8 test rig. Moreover, its density is only half that of a PFPE grease. This offers the advantage of extended grease life and reduced consumption costs. Lastly, the fully synthetic high-temperature grease shows better degradability and sustainability than PFPE-based products.
