Castrol Optitemp® HT 2 & HT 2 EP
High Temperature Greases for Long-term Lubrication
Description
Castrol Optitemp® HT 2 & HT 2 EP are high performance greases for long-term lubrication of rolling and sliding bearings at high operating temperatures as well as at normal or medium bearing pressures. Castrol Optitemp® HT 2 light-colored, while Castrol Optitemp® HT 2 EP has a dark color due to the molybdenum disulphide contained in it. It features an even higher load bearing capacity and good emergency running properties.
Applications
For thermally loaded rolling and sliding bearings such as fan bearings in the textile, wood, plastics and food industries as well as in stove furnaces of the automotive industry
For steam-heated calender or drying cylinder bearings
As sealing grease for labyrinth seals at high temperatures
For the application in slightly acidic or alkaline atmospheres
Castrol Optitemp® HT 2 EP is especially suited for friction points subjected to increased loads or when special emergency running poperties are required
Both greases are USDA-H2 authorized and suited for the use in the food and beverage industries.
Advantages
Optitec® - Optimol technology
Optimum wear protection in the high load range
Extremely good load bearing capacity
Especially aging and temeratures-resistant
Structurally stable
Resistant to cold and hot water, limited resistance to alkalis and acids
Excellent corrosion protection
Pumpable in central lubrication systems
Temperature application range: - 20°C/- 4°F to 160°C/320°F. In case of life lubricated bearings the temperature of 150°C/302°F under normal conditions should not be exceeded. Short-term operation at higher temperatures is possible - please consult out Technical Service.
