LUBRICATION OBJECTIVES

1. REDUCE FRICTION

2. REDUCE WEAR

3. PREVENT RUST AND CORROSION

4. SEAL OUT CONTAMINATION

5. ABSORB AND DISSIPATE HEAT

6. REDUCE NOISE

Most greases consist of a base oil, a thickener, and additives. The combination of these three components keeps the base oil in suspension until it is released through either heat or mechanical motion or a combination of both.

Our standard grease is capable of performing over a very wide range of temperatures (-20 to +350 F ⁰ ) as a general rule. There are however, applications which may require lower or higher operating ranges.

In the case of a bearing operating in low temperatures, our standard grease may perform well in the bearing as long as the bearing is in continuous motion. There could be problems however, in starting torque, if the bearing is allowed to cool to temperatures approaching the low end of its range. Depending on the actual application and the accuracy of the information from our customers regarding the application, LYF personnel will be able to make a recommendation concerning a suitable grease.

In high temperature applications, thermal stability and oxidation resistance must be considered. Again, our standard Chevron SRI #2 has those properties and will perform up to 350 degrees F. There are other greases however, with particular properties that may make them more suitable for a particular application even when their basic temperature ranges are the same.
