Spherical Ball Bearing Introduction
Spherical ball bearings is actually a variant of deep groove ball bearings,
is characterized by its outer diameter surface of the sphere,
it can be equipped into play within the corresponding concave spherical
bearing self-aligning role.
Although its basic properties and deep groove ball bearings should be similar,
but because most of the bearings used in the rough mechanical,
the installation location is not precise enough, the axis of the shaft and
housing bore neutral difference, or the long axis deflection By and large the case,
and bearing itself precision is not high enough, some structure is relatively coarse,
so the actual performance of the performance of the same size deep groove ball bearings
play on a considerable discount.
Spherical bearings priority for applications that require simple equipment and
spare parts occasions, such as for agricultural machinery,
transportation systems or construction machinery.
Mainly used to bear radial load mainly radial and axial load, generally should not
alone bear the axial load, such bearings can be installed separately inner ring
(with the whole group of roller and cage) and the outer ring.
This kind of bearing does not allow the shaft relative to housing is inclined in
the radial load appointments will produce additional axial force.
This kind of bearing axial clearance of the size of the bearing can work in it
when the axial clearance is too small, the higher temperature;
axial clearance is large, bearing easily damaged. Therefore, the installation and
operation of special attention to adjust the bearing axial clearance,
if necessary, preloaded installation, in order to increase the rigidity of the bearing.
The SKF Spherical ball bearing mainly be produced in Sweden SKF factory.
As a professional authorized distributor of branded bearings,
BEST Bearing Group has plenty Sweden SKF bearing, German FAG bearing, Japan NSK bearing in stock.
