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.
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.
