What type of lubricant is suitable for extreme temperature conditions?

Synthetic lubricants are specifically designed to perform well under extreme temperature conditions, making them the optimal choice in environments that may expose bearings to high heat or frigid cold. They have a broader operating temperature range compared to petroleum-based lubricants and are less likely to break down or lose viscosity in extreme conditions.

While petroleum-based lubricants can handle a range of temperatures, they often begin to break down at high temperatures, leading to decreased protection and performance. Water-based lubricants are unsuitable for extreme temperatures because they can easily evaporate or freeze, impacting their effectiveness. Animal fats also have limitations, as they may not maintain their performance across a wide temperature range and are prone to oxidation and rancidity. Thus, synthetic lubricants are the most reliable choice for ensuring optimal performance in challenging thermal environments.
