High Precision Needle Bearings NA-2RS Series is characterized by multiple structures,broad adaptability and easy installation.
Needle Bearings With Inner NA-2RS Series is widely used in automobile,machine toll,lathe,metallurgical,textile,printing industry and etc. Various machinery equipment. With this kind of bearing,machine design can realize the goal of small-scale & light weight.

Seal Ring Needle Bearings NA-2RS Series 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.

Features
Lowest cross section among rolling bearings 
In applications where less space is available, needle roller and cage assemblies offer a very compact solution.
High load carrying capacity 
Due to their large number of rollers, needle roller and cage assemblies have a high load carrying capacity. 
High stiffness 
Due to their large number of small-diameter rollers, needle roller and cage assemblies have high stiffness.
