NA 4852 needle roller bearing is equipped with thin and long rollers (the roller length is 3 ~ 10 times the diameter, and the diameter is generally no more than 5mm). Therefore, the radial structure is compact. Its inner diameter size and load capacity are the same as other types of bearings, and its outer diameter is the smallest. It is especially suitable for the supporting structure with limited radial installation size. According to different application occasions, the machining accuracy and surface quality of needle roller bearing shall be combined with the bearing ring and purpose. Needle roller bearing is a bearing unit composed of centripetal needle roller bearing and thrust bearing components.
