    100mm Bore Cylindrical Roller Bearing NU 420 / NU 420 M Single Row 250mm

    100mm Bore Cylindrical Roller Bearing NU 420 / NU 420 M Single Row


    Cylindrical roller bearing are of high load capacity and can operate at high speeds because they use rollers as their rolling elements. They can therefore be used in applications involving heavy radial and impact loading.

    The rollers are cylindrical in shape and crowned at the end in order to reduce the stress concentrations. They are also suitable for applications that require high speed because the rollers are guided by ribs which are either on the outer or inner ring.


    Feature:


    High load carrying capacity

    High stiffness

    Accommodate axial displacement
    Except for bearings with flanges on both the inner and outer rings.

    Low friction (Roller end / flange contact area)
    The open flange design , together with the roller end design and surface finish, promote lubricant film formation resulting in lower friction and higher axial load carrying capacity.

    Long service life
    The logarithmic roller profile reduces edge stresses at the roller/raceway contact and sensitivity to misalignment and shaft deflection.

    Enhanced operational reliability
    The surface finish on the contact surfaces of the rollers and raceways supports the formation of a hydrodynamic lubricant film.

    Separable and interchangeable
    The separable components of SKF cylindrical roller bearings are interchangeable . This facilitates mounting and dismounting, as well as maintenance inspections.
