Spherical bearings are advanced structural supports that utilize a spherical force transmission mechanism to perfectly address the needs of large-span bridges for immense load-bearing capacity and multi-directional rotation. Their main advantages are as follows:
Firstly, they offer flexible rotation and high load capacity. The core of their design is the sliding movement of the spherical lining plate, which results in an extremely low rotational frictional moment. This allows them to easily accommodate large angles of rotation caused by loads and temperature changes, while simultaneously providing exceptionally high compressive load-bearing capacity, making them suitable for large bridges and structures.
Secondly, they provide superior displacement capability. Through the use of guided or non-guided configurations in their horizontal sliding components, spherical bearings can effectively release or restrict longitudinal and transverse displacements, offering reliable constraint and support for complex structural systems.
Finally, they exhibit excellent durability and require minimal maintenance. These bearings typically incorporate high-performance sealing rings and low-friction materials, and can be designed with internal oil reservoirs for long-term lubrication. This significantly reduces wear, extends service life, and minimizes the need for upkeep.
