Product Description:

Radial Needle Roller and Cage Assemblies   

The assembling unit of needles and retainer is an independent element; each needle is accurately guided and kept in position by retainer. The design gives the bearing a large load-bearing capability and gives a large stiffness under a condition of minimum space. 
The distance length between both guide surfaces of retainer is large to ensure an accuate for the assembling unit of needles and retainer. 
The assembling unit of needles and retainer is suitably used in the place where the shaft and the seat hole can be used as the rolling race. If the dimensions and geometric shape of races on shaft and seat hole are accurate ,it can get a high rotary accuracy. 
The operation clearance of bearing depends on the tolerance of internal and external race, the needle type and the operation temperature.The necessary tolerance range at different running condition can be selected from table 1. 
For the assembling unit of needles and retainer, its space bength between the axial positioning surfaces shall comply with HII"BC".
