Cylindrical Wheel Bearing

One, the inner ring double guard, cylindrical roller bearing structure in the form of different outer rim
 

(1) no guard single row cylindrical roller bearing outer ring, model for n***0 type. Circle of its components can be separated from the outer ring, can't bear axial load, the influence of shaft installed in scale and machining error, easy for free end bearing (floating).

(2) a single guard single row cylindrical roller bearing outer ring, the model for nf***0 type. Respectively installed outer and inner components, can withstand the axial load in one direction, in the absence of a fixed end and free end to distinguish, can use a pair.
(3) the outer ring no guard with double lock ring of single row cylindrical roller bearings, for ncl***0v type. This kind of bearing with no cage, the number of roller is more, compared with the same size bearing model can withstand the bigger radial direction load, very eye speed is relatively lower. But due to the effect of double ring, can't separate installation, fixed end bearing.
 

(4) the outer ring type single row cylindrical roller bearings for rn***0. This kind of bearing the biggest advantage is the installation position of the radial dimension reduction, install the bearing housing is equivalent to the bearing outer ring, the escrow n***0 type bearing outer ring, bearing capacity, and its type ring and roller cage with n***0 gm.

2. Outer double guard, different guard forms of cylindrical roller bearing inner ring structure
(1) no guard single row cylindrical roller bearing inner ring, for nu***0 type. Can install inner ring and outer ring components respectively, not limit shaft and the shell axial displacement, unable to bear axial load, a free end bearing.
(2) a single guard single row cylindrical roller bearing inner ring, for nj***0 type, can be installed in the separation, can withstand the axial load in one direction, in the absence of a fixed end and free end to distinguish, can use a pair.
(3) the inner ring has a single guard with a retaining ring single row cylindrical roller bearings, for nup***0 type, have the ability to withstand two-way axial load. Flat collar to separate, inner ring axial fixation, used as a fixed end bearing.
(4) the inner ring with a helical baffle ring for the nj type single row cylindrical roller bearings, for nh***0 type, have the ability to withstand two-way axial load. Helical baffle ring to separate, inner ring axial fixation, used as a fixed end bearing.
