Product Description:
Spherical roller bearings are a type of rolling bearings that
possess the capability of withstanding large radial loads and
certain axial loads. The remarkable feature of these bearings is
that the centers of their inner and outer rings can be tilted to
the axis. As a result, they can automatically adjust their centers
and possess the ability to align themselves.
The spherical roller bearings are designed with double-row rollers,
a common spherical raceway on the outer ring, and two inner ring
raceways that are tilted at an angle relative to the bearing axis.
With this unique structure, these bearings can automatically adjust
axis misalignment which can be caused by the deflection or
non-concentricity of the shaft or housing. They provide excellent
aligning performance in this manner.
Features:
The spherical roller bearing has an automatic self-aligning
property, which is a result of its design. The presence of a
spherical raceway between the inner and outer rings of the bearing
enables it to automatically adjust the deviation of the axis and
maintain stable operation even if the shaft or housing is deflected
or not concentric. This feature greatly reduces the requirements
for installation accuracy and prolongs the service life of the
bearing.
Aside from its automatic self-aligning capability, the spherical
roller bearing also boasts a high load-bearing capacity. Its
double-row roller structure and spherical raceway design between
the inner and outer rings enable the bearing to maintain stable
operation when bearing heavy loads. This feature effectively
disperses the load and minimizes stress concentration on the
bearing.
The spherical roller bearing can also withstand impact loads due to
its automatic self-aligning and high load-bearing capacity. This
makes it ideal for mechanical equipment that requires stability and
durability when bearing impact loads.
In terms of applicability, the spherical roller bearing has an
inner hole that is cylindrical and conical. The tapered inner hole
bearing is equipped with a tightening sleeve or a withdrawal
sleeve, which allows for easy assembly on smooth or stepped machine
shafts. This design enables the bearing to adapt to a variety of
installation requirements and improve its applicability.
The spherical roller bearing operates smoothly, maintaining a
stable state during operation and reducing vibration and noise.
This helps to enhance the operating efficiency and service life of
mechanical equipment while also reducing noise pollution in the
surrounding environment.
Maintenance of the spherical roller bearing is relatively simple
and easy. Disassembly and installation can be done quickly when
replacement or maintenance is needed, reducing downtime and
maintenance costs.
