The Drawings:
NU design
The outer ring of an NU design bearing has two integral flanges
while the inner ring has no flanges. Axial displacement of the
shaft with respect to the housing can be accommodated in both
directions.
N design
The inner ring of an N design bearing has two integral flanges
while the outer ring has no flanges. Axial displacement of the
shaft with respect to the housing can be accommodated in both
directions.
NJ design
The outer ring of an NJ design bearing has two integral flanges and
the inner ring has one integral flange. These bearings can locate
the shaft axially in one direction.
NUP design
The outer ring of a NUP design bearing has two integral flanges and
the inner ring has one integral flange and one non-integral flange
in the form of a loose flange ring. These bearings can be used as
locating bearings to locate the shaft axially in both directions.
Spherical Roller Bearings Features:
Spherical roller bearings are a double row, self-retaining units
comprising solid outer rings with a concave raceway, solid inner
rings and barrel rollers with cages. The inner rings have
cylindrical or tapered bores.
The symmetrical barrel rollers orient themselves freely on the
concave outer ring raceway. As a result, shaft flexing and
misalignment of the bearing seats are compensated.
Radial and axial load capacity:
Spherical roller bearings can support axial forces in both
directions and high radial forces. They are designed for very high
load carrying capacity and, since they have the maximum possible
number of large and particularly long barrel rollers, are also
suitable for the heaviest loads.
Due to the narrow osculation between the rollers and raceways, the
uniform stress distribution is achieved in the bearing.
