 Hi-Temp Grease #286 is a high temperature synthetic silica-thickened anti-wear extreme pressure grease that is specially formulated for those industrial bearing applications, where extremely high temperature up to 900°F (482°C) are encountered.
Hi-Temp Grease is compounded from a blend of polyethylene glycol synthetic base fluids and silica based thickener system. Further compounded into these polyethylene glycol synthetic base fluids and the silica gel based thickener system is a proprietary blend of high temperature antiwear extreme pressure additive and a combination of molybdenum disulfide and graphite.
As high temperatures occur the High Temperature Grease will gradually soften in consistency without any drippage of the synthetic base fluids in order to carry and spread the molybdenum disulfide and graphite into the bearing clearances and onto the bearing surfaces. As the temperatures continues to become elevated the synthetic base fluids begin to volatize off cleanly without leaving any residues, varnishes, gums or carbon deposits on the bearing surfaces. Once the synthetic base fluids have completely volatilized off a solid lubricant film consisting of the proprietary high temperature anti-wear extreme pressure additive and the combination of molybdenum disulfide and graphite is left behind to lubricate at temperatures up to 900°F (482°C).
Hi-Temp Grease high temperature extreme pressure additive, molybdenum disulfide and graphite have a natural affinity for metal surfaces. This natural affinity for metal surfaces allows this solid lubrication combination to plate themselves to these surfaces in order to form a long lasting solid lubricant film which not only withstands high temperatures, but also will withstand pressures in excess of 500, 000 psi. This long lasting solid lubricant film provides the metal surfaces of the bearings the superior protection they need especially during periods of high shock loading, extreme pressure and vibration.
The solid lubricant film also helps to reduce friction. This reduction in friction results in reduced wear which in turn leads to increased bearing life, energy savings, less downtime and extended lubrication cycles.
High Temperature Grease also has excellent rust and oxidation inhibiting characteristics, very good water resistance and good mechanical and shear stability. Further, the Hi-Temp Grease’s adhesive properties prevent the Hi-Temp Grease from washing out, pounding out, splattering or being squeezed out even under the heaviest loads and vibrations. |
