High Quality Bearing FAK Cylindrical Roller Bearing RN312

High Quality FAK RN312 For Generators Cylindrical Bearing

    Roller bearing is one of the rolling bearings, which is widely used in modern machinery.It relies on rolling contact between the main components to support the rotating parts.Roller bearings are now mostly standardized.Roller bearing has the advantages of small torque required for starting, high rotation accuracy and convenient selection. 
 

Product Name	cylindrical roller bearing
Material	bearing steel
Color	Original steel color
Standard	DIN GB ISO JIS
Application Area	Mining/metallurgy/agriculture/chemical industry/textile machinery

Characteristics:

    Less friction and low noise, durable.
    Ability to carry heavy loads
    Less coefficient of friction.
    High limiting speed.
    Variations of structure:N,NU,NJ,NF,NUP,NFP,NH,NN,NNU,NNF,FC,FCD.

Physical Characteristics:

    Cylindrical roller bearing can be separated by single row,double rows, and four rows.
    This kind of bearing can be submitted to high radial load and some axial load.
    The rolling element of a cylindrical roller bearing is cylinder, the two ends of the external lines have the corrective slope which can eliminate the contact stress.
    NN and NNU design cylindrical roller bearing have high rigid and apply to machines such as milling

Types of Cylindrical roller bearing: 

    N series cylindrical roller bearing design The inner ring has two integral flanges and the outer ring is without flanges. Axial displacement of the shaft with respect to the housing can be accommodated in both directions within the bearing itself. The bearings are therefore used as non-locating bearings.
  
    NU series cylindrical roller bearing design The outer ring of bearings of the NU design has two integral flanges and the inner ring is without flanges. Axial displacement of the shaft with respect to the housing can be accommodated in both directions within the bearing itself.
 
    NJ series cylindrical roller bearing design The outer ring has two integral flanges and the inner ring one integral flange. The bearings are therefore suitable for the axial location of a shaft in one direction.
 
    NF series cylindrical roller bearing design The outer ring has one integral flange and the inner ring two integral flanges.
 
    NP series cylindrical roller bearing design The outer ring has one integral flange and one non-integral flange in the form of a loose flange ring and the inner ring two integral flanges.
 
    NUP series cylindrical roller bearing design The outer ring has two integral flanges and the inner ring one integral flange and one non-integral flange in the form of a loose flange ring. The bearings can be used as locating bearings, i.e. they can provide axial location for a shaft in both directions.
 
    RN series cylindrical roller bearing design No outer ring and the inner ring two integral flanges.
