The needle bearing is a roller bearing with a cylindrical roller, which is both thin and long with respect to its diameter. This kind of roller is called a needle roller. In spite of the smaller cross-section, the bearing still has a high load bearing capacity, the needle roller bearing is equipped with thin and long rollers (roller diameter D ≤ 5mm, L/D ≥ 2.5, L is the length of the roller), therefore The radial structure is compact, and the inner diameter size and load capacity are the same as those of other types of bearings, and the outer diameter is the smallest, which is particularly suitable for a support structure in which the radial installation size is limited.

According to different occasions, the inner ring bearing or needle roller and cage assembly can be used. The journal bearing surface and the housing hole surface matched with the bearing directly serve as the inner and outer rolling surfaces of the bearing to ensure load capacity and running performance. As with a bearing with a ring, the hardness of the raceway surface of the shaft or housing bore, the machining accuracy and the surface quality should be similar to the raceways of the bearing ring. This type of bearing can only withstand radial loads.
