Spherical joint bearings are widely used in hydraulic cylinders, forging machines, construction machinery, automation equipment, automotive shock absorbers, and hydraulic machinery. Spherical joint bearings are spherical plain bearings, consisting of inner and outer rings with spherical sliding contact surfaces. Depending on their structure and type, they can withstand radial loads, axial loads, or a combination of radial and axial loads.
Spherical joint bearings have a large spherical sliding contact area and a large tilt angle. Furthermore, most spherical joint bearings utilize special treatments such as phosphating, galvanizing, or chrome plating, or external sliding surface lining, inserts, or spray coatings. These bearings offer high load capacity and impact resistance. They are also corrosion-resistant, wear-resistant, self-aligning, and lubricate well or are self-lubricating, free of contamination. They also maintain proper operation even if misaligned. Therefore, spherical joint bearings are widely used in low-speed swinging, tilting, and rotational motions.
