Specifications

These bearings belong to the removable ones, which are convenient in mounting and dismounting.
Cylindrical roller bearings are classified as single row, double row and multiple row, of which the
single row cylindrical roller bearings with cage are more applied.

In general, the cylindrical roller bearings can only carry radial loads. Only the single row
cylindrical roller bearings with inner rings and outer rings having ribs can a certain smaller
amount of constant axial loads or bigger amount of intermittent axial loads be carried. Generally
for cylindrical roller bearings the shafts are not allowed to incline to the outer housings. However
for single row cylindrical roller bearings, under the condition of light loads, the inner rings and
outer rings are allowed to incline to each other for 2' ; under the condition of bigger loads, errors
can be allowed to be slightly bigger, but not more than 4'.

According to the different ribs of rings, the single row cylindrical roller bearings fall into the following
types: type N0000(2000)-the outer rings have no ribs and the inner rings have double ribs; type
NU0000(32000)-the inner rings have no ribs and the outer rings have double ribs; type
NF0000(12000)-the inner rings have double ribs and the outer rings have single ribs; type
NUP0000(92000)-the outer rings have double ribs and the inner rings have single ribs plus
flat snap sings ect.
 
Size: bore diameter 20 to 150mm
Series: N, NF, NJ, NP, NUP, NU, NN, NNU
Support heavy-radial loads and are suitable for high-speed operations
 
 
 
Single row cylindrical roller bearing
Single row cylindrical roller bearings are manufactured in several different designs, the main
difference being in the configuration of the flanges. The most popular are the NU, N, NJ and NUP
designs.
Cylindrical roller bearings can accommodate heavy radial loads and high speeds. Some with
different strcuture of ribs can also bear one way ot two way axial load. NN and NNU double row
cylindrical roller bearings have a low cross section, high load carrying capacity and high stiffness,
therefore it is mostly used in machine tool spindle stands. FC, FCD, FCDP four row cylindrical roller
bearings with large capacity of radial load, mostly applied in rolling mill and heavy machinery.
