Rod end bearings consist of a spherical ball that is inserted into the end of a rod with an outside thread or inside thread. The maintenance-free igubal® rod end bearings usually have a large bearing clearance, which allows them to be used at high peripheral speeds. The rod end bearings ensures low-noise operation even in the case of high-frequency oscillations and vibrations. The shaft should rotate within the bearing ball made of iglidur® materials. Due to the combination of steel shaft and spherical rod end bearing made of plastic, high speeds are possible in dry operating mode.
