Product description
Material & Process:
- Made of bearing steel (such as GCr15) or stainless steel, offering high strength, high hardness and excellent wear resistance. Some variants are phosphated or nickel-plated to improve rust and corrosion resistance.
- The inner and outer spherical surfaces are precision ground with low roughness and high sphericity, ensuring smooth sliding and even load distribution.
- Built-in seals made of nitrile or fluorine rubber effectively prevent dust and contaminants from entering while keeping lubricating grease from leaking out, extending bearing life.
- Some variants feature self-lubricating coatings (such as PTFE) on the inner or outer ring, enabling maintenance-free operation under oil-free or low-oil conditions.
Application:
This spherical plain bearing is mainly used in articulated joints that need to withstand radial loads while accommodating angular misalignment, allowing oscillating or tilting motion within a certain angular range. It is widely used in construction machinery, automotive suspension and steering systems, hydraulic cylinders, automation equipment, aerospace applications and various linkage mechanisms. It not only carries radial loads but also compensates for installation errors, deformations or angular deviations between the shaft and housing bore, reducing jamming and wear during operation and improving the flexibility and reliability of the mechanism. Maintenance-free models can be used in scenarios where regular lubrication is inconvenient, effectively reducing equipment maintenance costs and extending overall service life.
