Needle roller bearings (b) are roller bearings with cylindrical rollers that are thin and long relative to their diameter. Such rollers are called needle rollers. Despite their smaller cross-sections, the bearings still have With high load bearing capacity, needle roller bearings are equipped with thin and long rollers (the roller diameter, , is the roller length), so the radial structure is compact. When the inner diameter size and load capacity are the same as other types of bearings, the outer diameter The smallest diameter, especially suitable for support structures with limited radial installation size
Depending on the application, a bearing without an inner ring or a needle roller and cage assembly can be selected. At this time, the journal surface and shell match the bearing. The hole surface directly serves as the inner and outer rolling surfaces of the bearing. In order to ensure that the load capacity and operating performance are the same as those of bearings with rings, the hardness, processing accuracy and surface quality of the raceway surface of the shaft or shell hole should be similar to the raceway of the bearing ring. .This kind of bearing can only bear radial load
