Description
Castrol Tribol GR HT 2 High-temperature grease for long-term lubrication
Castrol Tribol™ GR HT 2 (previously called Optitemp™ HT 2) is high performance grease for long-term lubrication of rolling and sliding bearings at high operating temperatures as well as at normal or medium bearing pressures. Tribol GR HT 2 is light-colored.
Application
- 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
- 452.51As sealing grease for labyrinth seals at high temperatures
- For the application in slightly acidic or alkaline atmospheres
Advantages
- Optimum wear protection in the high load range
- Extremely good load bearing capacity
- Especially aging and temperature-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 our Technical Service.
