Specification: | IKO Spherical Bushings are self-aligning spherical
plain bushings that have inner and outer rings with
spherical sliding surfaces, and can take a large radial
load and a bi-directional axial load at the same time.
There are many types of Spherical Bushings, but they
are basically divided into steel-on-steel types and
maintenance-free types according to the kind of sliding
surfaces.
Steel-on-steel Spherical Bushings have inner and
outer rings of high carbon chromium bearing steel, of
which sliding surfaces are phosphate-treated and
then dry-coated with molybdenum disulfide ( MoS2) .
They can, therefore, operate with low torque, and
have excellent wear resistance and large load capacity.
They are especially suitable for applications where
there are alternate loads and shock loads. They have
wide applications mainly in industrial and construction
machinery.
Maintenance-free Spherical Bushings consist of an
outer ring which has a special PTFE liner reinforced
with copper alloy meshes on the sliding surface, and
a spherical inner ring of which sliding surface has a
hard chromium plating. Creep deformation due to
compressive load is small, and wear resistance is
superior. Thus, they are maintenance-free and can
be used for extended periods of time without re-lubrication.
They are especially suitable in cases where
fixed directional loads are applied and are used mainly
in food processing machines and construction
machinery and in other applications in which the use
of oil is undesirable or lubrication is not possible. |
