Grease lubrication is a method of reducing friction between moving parts in machinery by using a thick, semi-solid substance called grease. This grease is made from a base oil, thickening agents, and additives, which help it adhere to surfaces and provide a protective barrier against wear and corrosion. It is commonly used in applications where oil might leak or evaporate, such as in bearings and gears. One of the main advantages of grease lubrication is its ability to stay in place, providing long-lasting protection. It also helps to seal out contaminants like dirt and moisture, which can damage machinery. Grease is often preferred in applications involving heavy loads or extreme temperatures, making it suitable for various industries, including automotive and manufacturing.
