Introduction
WANBAO spherical bearings ensure the transfer of loads between a structure’s superstructure and its sub-structure. Meanwhile, they can accommodate rotation and movements of the superstructure. WANBAO spherical bearings are generally suitable for the use in any type of structure, especially for large loads and rotation.
WANBAO spherical bearings are designed and manufactured acc. to customer requirements, in accordance with relevant standards such as EN 1337, AASHTO, BS5400 or AS 5100.
