Spherical plain bearings are primarily sliding bearings with a special structure consisting of an inner ring with an outer spherical surface and an outer ring with an inner spherical surface.

Spherical plain bearings can withstand large loads. Depending on their type and structure, they can withstand radial loads, axial loads, or combined radial and axial loads.  Because the outer spherical surface of the inner ring is lined with composite material, the bearing is self-lubricating during operation. They are generally used for low-speed oscillating motion and low-speed rotation, and can also perform tilting motion within a certain angular range. They can still operate normally even when the shaft and housing bore have significant misalignment. Self-lubricating spherical plain bearings are used in industries such as water conservancy and specialized machinery.

Spherical plain bearings are widely used in engineering hydraulic cylinders, forging presses, construction machinery, automation equipment, automotive shock absorbers, and water conservancy machinery. Introduction and Classification of Spherical Plain Bearings: Spherical plain bearings are spherical sliding bearings. The basic type consists of inner and outer rings with spherical sliding contact surfaces. Depending on their structure and type, they can withstand radial loads, axial loads, or combined radial and axial loads.

Because spherical plain bearings have a large spherical sliding contact area and a large tilt angle, and also because most spherical plain bearings use special processing methods, such as surface phosphating, galvanizing, chromium plating, or outer sliding surface lining, padding, and spraying.

Therefore, they have a large load capacity and impact resistance, and possess characteristics such as corrosion resistance, wear resistance, self-alignment, good lubrication or self-lubrication without lubricant contamination. They can even operate normally even with misalignment during installation.  Therefore, spherical plain bearings are widely used in low-speed oscillating, tilting, and rotating movements. Spherical plain bearings mainly consist of an inner ring with an outer spherical surface and an outer ring with an inner spherical surface.  Due to the completely different structure and working mechanism of spherical plain bearings compared to rolling bearings, spherical plain bearings have their own unique technical characteristics and maintenance requirements.
