This roller bearing structures are all spherical roller bearings to
the most simple . The bearing type commonly used in high-speed
applications.
Because the inner ring , outer ring and rollers for line contact ,
this bearing type have greater radial load capacity. A variety of
cylindrical roller bearing structure is
N, JN, NF, NU, RNU; fixed ribs ( flanges ) NH, NP, NUP, NUR; fixed
wall and ( live ) wall NU, NNU; double row bearings
Having an upper mounting flange or the wall of the inner and outer
rings have a living structure can withstand a small axial load, the
bearing of this type is due to the roller end surface and the
flange ( wall ) side of the axial sliding action between the
Therefore, the load received axial load limit .
Double row cylindrical roller bearings for high-speed ,
high-precision applications, such as lathes, milling machines and
machining centers with spindle bearing . Tapered bore bearing
radial clearance can be adjusted when the bearing is mounted on the
supporting journal .
Standard stamped steel cage for the (board ) or polyamide resin (
nylon ) 's . Maintain high strength brass machined bearing frame
for large size or high-speed applications.
