Introduction
Spherical joint bearing is a precision mechanical component designed to withstand radial, axial, or combined loads. Its spherical contact structure allows flexible rotation within a certain angular range, making it suitable for high-precision, high-impact, or complex working conditions. Our products are manufactured using advanced international processes, with strict control over materials and precision to ensure exceptional reliability and durability.
product highlights
Spherical joint bearing High-precision CNC grinding machines are used to process the spherical surface and raceway, with dimensional tolerances controlled within ±0.001mm and surface roughness Ra≤0.2μm, ensuring uniform fit clearance and smooth rotation.
The main body is made of GCr15 bearing steel (hardness HRC58-62), and the spherical surface is carburized and quenched, combined with a PTFE self-lubricating pad to significantly reduce the friction coefficient and extend service life by over 30%.
The spherical radius and contact angle are optimized for design, with a maximum radial load of up to 500kN (model-dependent), effectively absorbing vibrations and handling frequent start-stop or impact load conditions.
Allows a swing angle of ±15° (up to ±30° for some models), meeting the multi-angle movement requirements of complex mechanical structures such as robotic arms and suspension systems.

FAQ
Q: How do I select the right spherical plain bearing model?
A:Selection is based on:
Bore size (matching the installation shaft, standard 20-300mm, non-standard customization available);
Load type and magnitude (radial, axial, or combined load, refer to the maximum load parameters of the model);
Swing angle requirement (e.g., ±15° or ±30° rotation range for mechanical structures);
Working environment (galvanized/Dacromet coating for wet/corrosive environments, special materials for high-temperature conditions).
