Cylindrical Roller Bearing NJ2318 E.M1C3
The cylindrical roller bearings are separate. This kind of bearing simplifies mounting and dismounting and has heavy carrying capacity of radial loads.
We can supply many kinds of cylindrical roller bearings.
Single row: N, NU, NJ, NF, NUP, NCF and NJG
Double row: NNU, NN, NNC, NNCF and NNCL.
Four rows:SL series
N: The inner ring has two integral flanges and the outer ring is without flanges. Axial displacement of the shaft with respect to the housing can be accommodated in both directions within the bearing itself. Pressed steel and machined brass cages and allowed.
NU: The outer ring has two integral flanges and the inner ring is without flanges. Axial displacement of the shaft with respect to the housing can be accommodated in both directions within the bearing itself. Pressed steel and the machined brass cages are allowed.
NJ: The outer ring has two integral flanges and the inner ring has only one integral flange. The bearings are therefore suitable for the axial location of a shaft in one direction. Pressed steel and machined brass cages are allowed.
NF: The inner ring has two integral flanges and the outer ring has only one integral flange. The bearings can locate a shaft axially in one direction. Pressed steel and machined brass cages are allowed.
NUP: The outer ring has two integral flanges and the inner ring has one integral flange with one separating as flange ring. The bearings can be used as locating bearings, i.e. They can provide axial location for a shaft in both directions.
