Large size cylindrical roller bearings NN48/750 size 750X920X170mm
A. Standard single row cylindrical roller bearings are classified according to the different ring rib structure:
The outer ring of the N-type bearing has no ribs. Double ribs on the inner ring
NU type bearing has no ribs on the inner ring and double ribs on the outer ring
N-type or NU-type bearings can allow the shaft to make bidirectional axial displacement relative to the bearing housing within a certain range, so they are suitable for non-locating bearings.
B. Double-row cylindrical roller bearings have two structures: cylindrical bore and conical bore. This type of bearing has the advantages of compact structure, high rigidity, large carrying capacity, and small deformation after being loaded. It is especially suitable for machine tool spindles. To
The structural feature of NN type bearings is that the inner ring has double ribs and the outer ring has no ribs.
NNU type bearings have double ribs on the outer ring and no ribs on the inner ring
These two types of bearings do not limit the relative axial displacement between the shaft and the housing, and are suitable for non-locating bearings. The cage of this type of bearing mostly adopts a car-made solid cage.
C. FC type or FCD type four-row cylindrical roller bearings are used in heavy machinery such as cold and hot rolling mills and billeting machines. The bearings are separated. The bearing rings and rolling element components can be easily separated. The bearings are cleaned and inspected. It is easy to disassemble and assemble.
