Product Description:
Since the rollers of cylindrical roller bearings make line the contact with the raceways, these
bearings can support heavy rodial loads and are suitable for high speed operation.
Cylindrical roller bearings come in various configuration as shown in the dimensional table.
The rollers are guided by the collars of either the inner or outer ring.
Since NU and N type bearings are not provided with a collar on the inner and outer ring.
the inner and outer ring can flow axially relative to the other under an axial load. These
bearing are most suitable for use on the free side of the shalt.
Bearing type NJ, NUP and NF having collar ring on the both inner and outer ring and can
receive a certain amount of axial load. These bearing types are sometimes used on the fixed
side of the shalt.
Sinoe cylindrical roller bearings are separable, they can easily be mounted or dismounted,
in cases when interference fits are required.
TYPE E CYLINDRICAL ROLLER BEARINGS :
The boundary dimensions of type E cylindrical roller bearings are the same as those of the
standard type. The load capacity of type E bearings is increased by enlarging the roller
diameter, increased roller length, and by increasing the number of rollers. The bearings are
classified by attaching the suffix "E™ at end of the basic number.
Allowable misalignment
The allowable misalignment for cylindrical roller bearings is approximately 0.001 radian
(0°, 3.5’) for bearing series 0 and 1 and 0.115 radian (0°, 1.5‘) for bearing series 2. for
double row cylincial roller bearings. basically no misalignment is permitted
