Description
Imports of spherical ball bearings is actually a variant of
deep groove ball bearings, is characterized by a spherical surface
of the outer ring outside diameter, can be equipped with the
imported bearing concave spherical play a role in the
self-aligning.
Although its basic properties and deep groove
ball bearings should be similar, but due to this bearing is mostly
applied in the relatively coarse mechanical installed orientation
is not precise enough, the axis of the shaft and housing bore of
the neutral differential, or shaft length and deflection the big
case, and bearing its own accuracy is not high enough, some
structures are more rough, so a considerable discount on the total
performance of the actual performance of the same specifications as
deep groove ball bearings fight. For example, with the top wire of
the outer spherical ball bearings used in stiffness differential
deflection through shaft bearings on both sides with seals tight to
prevent dirt intrusion, Pat filling the right amount of lubricant
in the factory, and need not be washed before installation without
additional lubricant, bearing inner ring on the protruding end of
the top wire screw shaft fastening. Allowable axial load shall not
exceed *0% of the rated dynamic load.
With eccentric sleeve insert ball bearings and
spherical bearings performance with the top wire is basically the
same, just the top wire, not on the inner ring, but in the
eccentric sleeve. Bore tapered bore spherical ball bearings with
1:*2 taper tapered bore can be directly installed on the cone axis,
or through a tight set of bushings installed without shaft shoulder
on the optical axis, and can fine-tune the bearing clearance.
