 The cylindrical roller bearings of various structures are divided as per the different retaining edges. NU type cylindrical roller bearings have two retaining edges on the outer ring with non-retained inner ring. N type cylindrical roller bearings have two retained inner rings with non-retained outer ring. Both NU and N types cylindrical roller bearings are shifting bearings with separable inner and outer rings for easy dismounting. NJ type bearings have double retained outer rings with single retained inner ring. NF type bearings have double retained inner rings with single retained outer rings. They can bear the single directional axle force . NUP type cylindrical roller bearing is used as fixed bearing which can bear the alternative directional axial force. Bearings of this type have double retained outer ring with one retaining ring.


Re-enforced cylindrical roller bearing                                                                                       

To distinguish from the common cylindrical roller bearings, the re-enforce E cylindrical roller bearings are marked with the suffix E. This E type bearings have the same main dimensions as the common bearings except the increased diameter , length , and numbered of the rollers. The load capacity is also enhanced accordingly.

This type bearings have big rational load. So as shown in Figure, when compared with the common bearings of the same shaft diameter, the bearing outer diameter should be reduced or the shaft diameter should be increased when the bearings with same outer diameter are used so that the rigidity of the shaft can be enhanced.

Besides, the incircle of E type is different from the common bearings , so they are not inter-changeable.



Steel plate punched retainer or entity retainer are used with cylindrical roller bearings are common used for cylindrical roller bearings. But retainers made of fiber glass re-enforced nylon 66 is also used for the temperature of - 20?200C, or for 1500C short time operation.


Cylindrical roller bearings with stopping ring groove                                                                 

DEBU-cylindrical roller bearings SL04, 50 and SL 04 series , the bearings with single face or double face sealing are positioning bearings of two line and full-rollers. A complete unit is directly assembled with inner ring, rollers and outer ring. The cylindrical rollers are guided by the inner retaining edge while there is a entity middle retaining edge on the outer ring. There are two circle grooves on the outer surface. It is easily positioned in axial direction with the stopping ring. The seat width may be smaller than the width of the bearing so as to reduce the axial directional space requirement.
