Needle bearing inner sleeve is inner ring of needle bearings

Needle bearing inner sleeve is inner ring of needle bearings.
According to the use of different occasions, can be used without inner ring of the bearing or needle roller and cage components and needle bearing inner sleeve, 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.  

Needle bearing inner sleeve is a needle roller bearing with thin stamping outer ring.  Its main characteristics are low section height and high load bearing capacity.  
It is mainly used for the bearing configuration with compact structure and low price, and the bearing box hole cannot be used as the raceway of the needle holder assembly.  Bearings and bearing boxes shall be installed in interference-fit mode.  If the shoulder, stop ring and other axial positioning functions can be omitted, then the bearing box hole can be made very simple and economical.  

Solid ring needle roller bearings are composed of one or two rings and a needle roller group with a cage.  According to the different application, it can be divided into bearings with needle bearing inner sleeve or without needle bearing inner sleeve.  
Therefore, solid ring needle roller bearings can meet the requirements of light weight, small space occupation and large transmission power.  Solid ring needle roller bearing has smaller volume and higher bearing capacity.
