The needle bearing is equipped with thin and long rollers (roller diameter D 5mm, L / D 2.5, L is the roller length), so the radial structure is compact, its inner diameter size and load capacity are the same as that of other types of bearings, the outer diameter is the minimum, especially suitable for supporting results with limited radial installation size. According to the different use conditions, can choose the bearing or roller pin and holder components, matching with the bearing collar surface and the surface of the bearing, in order to ensure the load capacity and running performance as the ring bearing, the hardness of the surface of the shaft or shell bore, machining accuracy and surface quality should be similar to the roller way of the bearing ring. Such bearings can only withstand radial loads.
