2. Grease (lubricant) - Wikipedia

   en.wikipedia.org/wiki/Grease_(lubricant)

   Lithium-based grease has a dropping point at 190 to 220 °C (374 to 428 °F). However the maximum usable temperature for lithium-based grease is 120 °C. The amount of grease in a sample can be determined in a laboratory by extraction with a solvent followed by e.g. gravimetric determination. [6]

3. Dry lubricant - Wikipedia

   en.wikipedia.org/wiki/Dry_lubricant

   In an oxidative atmosphere, graphite is effective at high temperatures up to 450 °C continuously and can withstand much higher temperature peaks. Graphite is characterized by two main groups: natural and synthetic. Synthetic graphite is a high temperature sintered product and is characterized by its high purity of carbon (99.5−99.9% ...

4. Silicone grease - Wikipedia

   en.wikipedia.org/wiki/Silicone_grease

   Pure silicone grease is widely used by the plumbing industry in faucets and seals, as well as in dental equipment. This is because it is not an ingestion hazard [3] [better source needed]. Electrical utilities use silicone grease to lubricate separable elbows on lines that must endure high temperatures.

5. Dropping point - Wikipedia

   en.wikipedia.org/wiki/Dropping_point

   The heat is reduced until the test tube temperature is at most 4 °F (2.2 °C) less than the oil/block temperature. Once the temperature has stabilized the sample is inserted. The dropping point is the temperature recorded on the test tube thermometer, plus a correction factor for the oil/block temperature, when a drop of grease falls through ...

6. Vacuum grease - Wikipedia

   en.wikipedia.org/wiki/Vacuum_grease

   As well as a lubricant, vacuum grease is also used as a sealant for joints in vacuum systems. This is usually limited to soft vacuums, as ultra high vacuum or high temperatures may give problems with the grease outgassing. Grease is most commonly used with glass vacuum systems. [1] All metal systems usually use knife-edge seals in soft metals ...

7. Grease fitting - Wikipedia

   en.wikipedia.org/wiki/Grease_fitting

   Grease fitting on a bearing A grease nipple on the driver's door of a 1956 VW Beetle. A grease fitting, grease nipple, Zerk fitting, grease zerk, Alemite fitting, or divit is a metal fitting used in mechanical systems to feed lubricants, usually lubricating grease, into a bearing under moderate to high pressure using a grease gun.

8. Air bearing - Wikipedia

   en.wikipedia.org/wiki/Air_bearing

   Cables/tubes (motor, air bearing, measurement system) do not move in order to avoid breakages due to high load cycles. The air-bearings are absolutely insensitive against geometric fluctuation as a result of a temperature change. [15] Drive for production machine Beside the performance, the reliability is extremely important for a production ...

9. Extreme pressure additive - Wikipedia

   en.wikipedia.org/wiki/Extreme_pressure_additive

   Oil-soluble organophosphates, with or without zinc, have excellent high-pressure and antiwear properties, and provide corrosion protection especially in presence of chlorinated hydrocarbons. Zinc dialkyldithiophosphates (ZDDP) start decomposing at 130-170 °C, while the activation temperature of tricresyl phosphate (TCP) typically exceeds 200 ...
