Cylindrical 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. 

1. 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.
2. 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
