Construction of this roller bearing type is the simplest of all radial roller bearings. This bearing type is often used in high-speed applications. Because the inner ring, outer ring, and rollers are in line contact, this bearing type has a large radial load capacity.
Various Cylindrical roller bearing configurations are N,NJ,NF,NU,RNU: integral ribs (flanges) NH,NP;NUP;NUH: integral and loose ribs NN,NNU: double-row bearings. Configurations having integral flanges or loose ribs on both the inner and outer rings can sustain a small amount of axial load.
Since this bearing type supports axial loads as sliding action between the end of the rollers and flange faces, axial loading is Limited. Double-row Cylindrical roller bearings are used for high-speed, high-accuracy applications such as; main spindle support for lathes, milling machines, machining centers.
