Many users who are new to OFILL lubricating grease often focus only on the drop point when selecting high-temperature grease and overlook other aspects. This approach is not advisable. While the drop point is indeed an important indicator for measuring the high-temperature performance of grease, it is by no means the only one.
For example, many lubricating grease manufacturers take advantage of this 'high drop point means high-temperature resistance' perception among users. They often prominently display the 'drop point' in their product descriptions, with claims like 'Drop point: 380°C,' which is very enticing. However, the actual temperature it can withstand may not even reach 150°C.
In general, OFILL lubricating grease with a high drop point is typically suited for higher operating temperatures, but the actual operating temperatures for grease are usually within the range of 50°C to 100°C, which is below the drop point. The high-temperature performance of grease is primarily determined by the choice of base oil, and the selection of a good-quality base oil plays a crucial role in the grease's performance at both high and low temperatures.
Furthermore, the high-temperature resistance of grease is also influenced by factors such as the thickening method, the types and concentrations of additives, and various other aspects of the grease composition.
In summary, the selection of high-temperature grease should not be based solely on the drop point. Choosing an excellent and suitable grease is primarily determined by the specific equipment's requirements, and one should not hold the misconception that 'the higher the temperature rating of the grease, the safer it is to use.' This is to avoid falling into the misconception that 'a high drop point means high-temperature resistance.
