Klϋber Lubrication, a worldwide manufacturer of specialty lubricants, introduced Klübertherm HB 88-182 for the long-term lubrication of rolling bearings. This lubricating grease offers high-temperature properties and can be used for both 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.
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 compatibility with elastomer and thermoplastic components and seals. Klübertherm HB 88-182 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.
