The rolling body is a centripetal rolling bearing of a cylindrical roller. The internal structure of cylindrical
roller bearings adopts rollers arranged in parallel, and a spacer or isolation block is installed between the rollers,
which can prevent the tilt of the rollers
or the friction between the rollers, and effectively prevent the increase of rotation torque.

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
