What are self-lubricating bearings?
As the name suggests, self-lubricating bearings provide their own lubrication during operation without the use of grease or oil-based lubricants. Therefore, self-lubricating bearings also do not require lubrication or grease, so they are also called maintenance-free or grease-free bearings. An important difference is that self-lubricating bearings are not pre-greased bearings, but are called pre-lubricated bearings. Pre-lubricated bearings require relubrication at certain times during their service life. What is the importance of self-lubricating bearings in the aerospace industry?The aerospace industry requires low-friction bearings with excellent wear resistance to help reduce labor costs. Since many areas of the aircraft are difficult to maintain, they benefit from components with a long service life, namely self-lubricating bearings.
