Needle Roller Bearings Spherical Bushings

IKO Spherical Bushings are compact self-aligning spherical bushings with inner and outer rings in contact with the sphere, which can support a large radial load and a bi-directional axial load at the same time. There are many models 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 made of high-carbon chromium bearing steel. The sliding surfaces are phosphate-treated and then dry-coated with molybdenum disulfide (MoS2) so they can operate with low torque, and have excellent wear resistance and large load capacity. They are well suited for applications where there are alternate loads and shock loads, and they are used 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 on sliding surfaces with hard chromium plating. The creep deformation due to compressive load is small, and it has superior wear resistance. Also, since they are maintenance-free they can be used for extended periods of time without re-lubrication. They are most suitable when fixed directional loads are applied, mainly in food processing machines and construction machinery, and in other applications where the use of oil is undesirable or lubrication is difficult.
