The the sealed two sided self-lubrication rod end bearing,there is an hole in the outer ring,the material of outer ring is bearing steel.The spherica surface is pasted with some PTFE textile.Inner ring,the material is also bearing steel ,hardened,some hard chromium is coated on the spherical surface,enjoys the qualities of self-lubrication,durable,self-aligning,low friction,suitable for the environment full of dust ,withstand radial load and light axial load from one direction.

It is a kind of special plain bearing.Main structure:consists of an inner ring with a outer spherical and outer ring with an inner spherical,can withstand heavy load.According to its different model and structure,can withstand radial load,axial load or both of them.Ausually,they are utilized in the wobble accassion whose rotational speed is low.Because the plain surface is in spherical shape,it can incline towards some space within certain angular.

This series of bearings can be classified into plain radial bearings,angular contact rod end bearings,thrust rod end bearing and spherical plain bearings.
