Bushings are small aircraft parts used in the aerospace and military industries.  They are crucial for reducing friction in key parts of an aircraft and act as a barrier between moving parts, ensuring that they glide smoothly against each other with minimal resistance. Reducing friction without oil or grease is especially important in high-stress areas where metal-on-metal contact could lead to wear and potential failure. 

Bushings also help with supporting loads during aircraft operation. Whether from external forces or internal mechanical stresses, significant loads can be experienced by aerospace components. Bushings help distribute these loads, preventing localized pressure points that could weaken or damage the surrounding structure.
