High Temperature Grease
Product Description
Mobiltemp 78 is a clay thickened high temperature grease based on a heavy viscosity mineral base oil. It is
formulated to provide low volatility, oxidation resistance and excellent structural stability at high temperatures,
resistance to water washing and good anti-wear performance under heavy loads and low speeds.
Features and Benefits
• Superior high temperature performance
• Will not soften and leak from bearings
• Good wear protection
• Good resistance to water washing and steam
• Extended relubrication intervals
• Lead, chlorine and nitrite free
Applications
Mobiltemp 78 is recommended for the lubrication of plain and anti-friction bearings in applications such as oven
conveyor or kiln bearings operating at low speed and high temperature or under cycling conditions from ambient
to high temperatures. The greases will not soften and leak under high temperature conditions or harden
excessively on cooling. Mobiltemp 78 is also suitable for the lubrication of cams, ways and other sliding machine
elements. The recommended operating temperature range is 0 to 170ºC with appropriate relubrication intervals.
