 Cylindrical roller bearings type from Ledun(Shanghai)Precision Bearing Co.,Ltd:

1.N, NU type 

N-type bearing outer ring without ribs , the inner sides of a wall . Allows the bearing axis relative to the axial direction 
between the two displacement directions . NU type ribs on both sides of the bearing outer ring , inner ring without ribs .
Can allow the shaft between the bearing seat in the axial displacement in both directions .
Therefore, such a structure is suitable for use as a mobile end bearings .

2.NJ, NF type

NJ-type bearing outer ring on both sides of wall, inner side with ribs . Can withstand a certain amount of axial load . 
NF type outer side has wall, inner sides of ribs .
Also can withstand a certain amount of axial load . Therefore, such a structure is suitable for positioning the axial direction as a single bearing .

3.NUP, NFP type

NUP type on both sides of the outer ring of the bearing wall , the inner side of the band ( fixed ) single-wall , 
while the other side is detachable flat ring . Can withstand a certain amount of axial load .

NFP type bearing outer side of the belt ( fixed ) single-wall , while the other side is detachable flat ring , the inner sides of ribs . 
Also can withstand a certain amount of axial load .
This class can limit bearing structure relative to the bearing shaft in the axial displacement in both directions . 
Therefore suitable for use as the fixed end bearings .

4.NH (NJ + HJ) type

NH NJ type bearings are bearings with thrust collar combination HJ -type structure . As NUP type bearing inner shorter and the flat ring is not fixed ,
inconvenient to use ,
The NH NJ type bearings can be used bearing the entire width of the inner ring with the shaft maintain closer cooperation. 
And NH-type bearings in the installation and removal easier .

NH-type bearings can limit the shaft relative to the housing in the axial displacement in both directions . 
Therefore suitable for use as the fixed end bearings .

Double row cylindrical roller bearings

Double row cylindrical roller bearings with cylindrical bore and conical bore ( bearing post code plus K) two structures. 
The bearing has a compact, rigid, carrying capacity,

By deformation after the load , etc., especially suitable for machine tool spindle bearing .
Conical bore can also play the role of micro- adjust clearance and positioning device can be simplified structure, 
easy installation and removal .
Commonly used double row cylindrical roller bearings under the following forms
