Needle bearing equipped with a thin and long roller (roller diameter D ≤ 5mm, L / D ≥ 2.5, L is the length of the roller), therefore radially compact structure, the inner diameter size and load capacity and other types of bearings with the same, the smallest outside diameter, especially suitable for the radial mounting of the support results of the size restrictions. Based on the use of different occasions, can be used without the inner ring of the bearing or needle roller and cage assemblies, the match with the bearing journal surface and the surface of the shell hole as bearing directly within the outer rolling surface, in order to ensure the load capacity and operation the same performance with rings bearing shaft or housing bore raceway surface hardness, machining accuracy and surface quality bearing ring raceway is similar. Such bearings can only bear radial load
