Description
Four row cylindrical roller bearings can carry much heavier radial load and shock load. They have higher precision and can be applied in the equipment which runs with high rotational speed. Grinding the surface of raceway and roller at same time after the inner ring is pressed on roller neck, it favors the improvement of rolling precision and the free adjustment of mounting clearance of bearings. These bearings are mostly applied to the working roller and backup roller of rolling mills and some other cases.
FC: double outer rings, single inner ring, and inner without flange.
FCD: double outer rings, double inner rings, and inner ring without flange.
FCDP: double outer rings, only have center flange, but with loose rib, double inner ring, inner without flange.Cylindrical roller bearings without outer ring capped edge
The NU cylindrical roller bearing has double capped edges on outer ring and without capped edge on inner ring
The N cylindrical roller bearing has double capped edges on inner ring and without capped edge on outer ring
The NU and N cylindrical roller bearings, the shaft is allowed two-way displacement toward the bearing box, i.e. the cylindrical roller bearings can bear the change of shaft length due to thermal expansion. Thus It is suitable to serve as a non-fixed bearing. It can bear larger radial load, but cannot take axial load.
Cylindrical roller bearings with capped edge on both outer ring and inner
The NJ cylindrical roller bearing has double capped edge on outer ring and single capped edge on inner ring.
The NF cylindrical roller bearing with the single capped edge on outer ring & double capped edges on inner ring
The NJ & NF cylindrical roller bearing, the axial-displacement of the shaft or housing on one-direction can be limited. The one-direction axial positioning can be reached. It can burden smaller axial load from one-direction.
The NUP cylindrical roller bearing with double capped edges on the outer ring & with capped edge on one side of the inner ring, as well as with inner ring loose rib on the other side of the inner ring. The two-way axial positioning toward the shaft can be reached. The bearing can bear two-way axial force. The NUP & N cylindrical roller bearings can be chosen for the structure. The NJ and HJ cylindrical roller bearing with separate thrust collar is similar to the NUP cylindrical roller bearing, it can be used as the fixed (positioning) bearing.
Cylindrical roller bearings without inner ring or without outer ring
The RNU cylindrical roller bearing has an outer ring with double capped edges but does not come with inner ring. Such bearing is the NU cylindrical roller bearings without the inner ring
The RN cylindrical roller bearing has an inner ring with double capped edge but does not come with outer ring.
The RNU and RN cylindrical roller bearing are used with a component having a limitation on radial dimension. The axial journal or the surface of the housing bore can be used as the raceways. The hardness and the machining precision as well as the surface quality should be same as the raceways of the inner ring and the outer ring.
PackageFor the medium and large size bearings,we usually pack it by wrapped belt and wooden case.This will avoid any damage to the bearing surface and make the bearing better performance when it arrives at the destination.Also,we can pack it by customer's requirement.| Bearing No | Dimension(mm) | Basic Loading(kN) | Mass(kg) |
