Cylindrical Roller Bearing

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:
NU, NJ, NUP: integral ribs (flanges)
(See the Cylindrical roller bearing dimensional data section for description of configuration design).
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.
