Needle roller bearings are equipped with thin and long rollers (roller length is 3~10 times of diameter, diameter is generally not more than 5mm), so the radial structure is compact, its inner diameter size and load capacity are the same as other types of bearings, and the outer diameter is the smallest, especially suitable for radial installation size limited support results. According to the use of different occasions, can be used without inner ring of the bearing or needle roller and cage components, at this time to suit the bearing surface of the surface of the shaft and the shell hole directly as inner and outer rolling bearing surface, in order to ensure the load capacity and operation performance and you have the same ring bearing, axis or shell hole hardness on the surface of the raceway, machining accuracy and surface quality should be as a bearing ring raceway. This kind of bearing can bear radial load only. SUNTHAI bearing

The release bearing is composed of raceway ring, needle roller and cage assembly. It can be arbitrarily combined with the thin raceway ring (W) processed by stamping or the thick raceway ring (WS) processed by cutting. The non-separation bearing is an integral bearing composed of the raceway ring, needle roller and cage assembly processed by precision stamping

Can bear unidirectional axial load

This kind of bearing occupies small space and is beneficial to compact design of machinery

Most use only needle roller and cage components, and the mounting surface of the shaft and housing as the raceway surface

Mainly applicable holder: steel plate stamping holder, synthetic resin forming holder

Main uses: variable speed device for automobiles, cultivators, machine tools, etc
