One of the main advantages of grease lubricants is their ability to remain in contact with moving surfaces without leaking out, even under high pressure or temperature fluctuations. This characteristic makes them ideal for applications where re-lubrication is challenging or infrequent. Grease also provides a barrier against contaminants, such as dust and water, which can cause significant wear and corrosion. Additionally, the use of grease can simplify the lubrication process, as it reduces the need for frequent application compared to liquid lubricants.
