Nachi Cylindrical Roller Bearings
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, and machining centers. Radial clearance of tapered-bore bearings can be adjusted during mounting of the bearing(s) onto the mating journal. Standard cages are pressed steel or polyamide resin. Machined cages of high-strength brass are used for bearings of large dimension or for high-speed applications.
