Joint ball supplier Introduction, A spherical plain bearing is a type of spherical sliding bearing. Its sliding contact surfaces consist of an inner spherical surface and an outer spherical surface, allowing it to rotate and oscillate at any angle during motion. It is manufactured through various specialized processes, including surface phosphating, oil impregnation, roll‑on coating, and spray coating. Spherical plain bearings feature high load-carrying capacity, impact resistance, corrosion resistance, wear resistance, self‑aligning capability, and excellent lubrication performance.
The joint ball supplier stated that, The structure of a spherical plain bearing is simpler than that of a rolling bearing, consisting primarily of an inner ring with a spherical outer surface and an outer ring with a spherical inner surface. Spherical plain bearings are typically used in low-speed oscillating (i.e., angular) motions. Because the sliding surfaces are spherical, they can also accommodate tilting within a certain angular range (i.e., self-aligning motion), allowing the bearing to function normally even when there is a significant eccentricity between the supporting shaft and the housing bore.
Spherical plain bearings can withstand substantial loads. Depending on their type and design, they are capable of handling radial loads, axial loads, or a combination of both. Thanks to the composite material embedded in the outer spherical surface of the inner ring, these bearings provide self‑lubrication during operation. They are typically used in low‑speed oscillating and low‑speed rotating applications and can also accommodate tilting motions within a certain angular range. Even when there is significant eccentricity between the shaft and the housing bore, they continue to function reliably. Self‑lubricating spherical plain bearings are employed in industries such as hydropower and specialized machinery.
The joint ball supplier stated that, Spherical plain bearings are widely used in industries such as engineering hydraulic cylinders, forging presses, construction machinery, automation equipment, automotive shock absorbers, and hydraulic machinery. Spherical plain bearings are spherical sliding bearings. The basic type consists of an inner ring and an outer ring, both featuring spherical sliding contact surfaces. Depending on their design and classification, they can accommodate radial loads, axial loads, or a combination of radial and axial loads.
Because spherical plain bearings feature a large sliding contact area and a wide allowable tilt angle, and because most of them are manufactured using specialized surface treatments—such as phosphating, zinc plating, chrome plating, or the application of liners, pads, or coatings on the outer sliding surface—they offer high load-carrying capacity and excellent shock resistance. They also exhibit corrosion resistance, wear resistance, self‑aligning capability, and superior lubrication performance, including self‑lubricating properties that minimize contamination from lubricant residues. Moreover, they can function properly even when misaligned during installation. Consequently, spherical plain bearings are widely used in low‑speed oscillating, tilting, and rotary motions.
