Cylindrical Roller Bearings
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
Various Cylindrical roller bearing configurations
are: N,NJ,NF,NU,RNU : integral ribs (flanges) NH,NP ,NUP
,NUB : integral and loose ribs NN,NNU : double-row bearings
(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,
applications such as; main spindle support for lathes,
milling machines, and machining centers.
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
of high-strength brass are used for bearings of large
or for high- speed applications.
