Bushings

Aircraft bushings are cylindrical bearings that support rotary operations. They are usually found in aircraft landing gear and helicopter rotors, as well as other components that provide rotary movement. The most common type of aircraft bushing is the sleeve bushing, which features specified inner and outer diameters, and is usually plated with a friction-reducing material such as Teflon to obviate the need for lubrication. Other designs include split bushings, which feature a cut along their length, and clenched bushings, which are split bushings with clenched or fastened cuts. Flanged bushings have a flange at one end to provide a thrust-bearing surface or to positively locate the part.
