Needle roller bearing has a compact radial structure

Needle roller bearings are equipped with thin and long rollers, so the radial structure is compact, and its inner diameter and load can be the same as other types of bearings, and the outer diameter is the smallest. It is especially suitable for supporting results where the size of the radial device is limited.

      Depending on the place of application, bearings without inner ring or needle roller and cage components can be selected. At this time, the outer surface of the journal and the outer surface of the housing hole that match the bearing are directly used as the inner and outer rolling surfaces of the bearing to ensure load capacity and running performance Same as the bearing with ring, the surface hardness, machining accuracy and appearance quality of the shaft or housing hole raceway should be similar to the raceway of the bearing ring. This type of bearing can only accept radial loads.

       I hope that the above actions can be understood in your application, and I would like to send you a call for consultation.
