Descriptions：
Needle roller bearing is a bearing unit composed of machined outer ring & inner ring,cage and needle roller assembly featuring small section height,big load capacity & rigidity,compact structure and small size,high rotating accuracy with the structure of disposed inner ring.
Needle roller bearings have large bearing capacity and are suitable for mounting support structures with limited dimensions. The surface of the journal is hardened as the rolling surface, and the bearing is pressed into the seat hole without axial positioning.
Needle roller bearing is characterized by multiple structures,broad adaptability and easy installation.
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.
Main applications of needle roller bearing:
It is used in various mechanical equipment such as machine tools, metallurgical machinery, textile machinery and printing machinery, and can make the mechanical system design very compact and dexterous.
Needle roller bearings are a bearing that is classified as either radial or thrust depending on the direction of the load being supported. Needle roller bearings include bearings whose rollers slightly exceed the size range of needle rollers as stipulated by ISO. Needle roller bearings include drawn cup and solid radial bearings, as well as application-specific cam followers, and roller followers. Thrust bearings include thrust needle bearings.Drawn cup needle roller bearings (with a cage and full complement of rollers) have a unique outer ring structure. They have the following features: the thinnest outer ring among rolling bearings, high load capacity, high maximum permissive load owing to the use of carefully selected special alloy steel plates, a surface-hardened cage with high resistance to wear, high limiting speed, and ease of mounting.
