Needle roller bearing

 

Needle Roller Bearings are the roller bearings with cylindrical roller elements, compared with the diameter, the needle roller are both thin and long, so they are called needle roller. Although the section is small, the type of bearings still has the high ablity of load, it specially can be used to the situation of being restricted of the radial space..

Product construction

 

Needle roller bearings consist of an inner race (shaft), needle cage, needle rollers and an outer race. The rollers are cylindrical, thin, and long. These bearings are compact because there is less clearance between the diameter of the shaft and that of the bearing. This quality makes them suitable for situations where there is limited radial space.

Material:

 

Material for needle roller is GCr15 bearing steel,quench-hardening HRC60-65

Material for inner and outer rings is GCr15 bearing steel,quench-hardening HRC60-65

Material for cages is quality low-carbon steel or reinforced nylon.

 

Special Directions:

 

Bearing running clearance and inner-cutting roundness should be regulated according to different

conditions.

 

Machine tolls should be used for press-in fitting or thermal fitting when install the bearing.

Limited by plastic cages(suffixed with TN) and sealing-element material ,operating temperature

is -30℃--+100℃

 

For general-disposition design of bearings,refer to the relevant recommendation in the applied

technology of roller bearings.
