Spherical Plain Bearings (Joint Bearings) feature a spherical sliding contact surface that allows angular misalignment and oscillating motion while reliably transmitting high radial loads and, depending on the design, axial loads in one or both directions. Their self-aligning structure helps compensate for mounting errors, shaft deflection, or housing deformation, ensuring stable performance under vibration, shock, and heavy-duty operating conditions. Available in maintenance-required (steel-on-steel) or maintenance-free (PTFE/liner) versions, spherical plain bearings are widely used in construction machinery, hydraulic cylinders, mining and metallurgy equipment, agricultural machinery, industrial linkages, and lifting systems, where durability and flexible alignment are essential.
