Spherical Bearing

Spherical bearing allows the rotation of the superstructure thanks to the sliding of a spherical calotte utilizing low friction materials. The displacement is achieved thanks to low friction materials sliding on stainless steel surfaces. In addition to the typical properties of pot bearings, spherical bearing also features larger rotation capability and higher durability. The vertical load is normally up to 150000 KN or more. This product can be widely applied to bridges, buildings and other civil engineering structures.

The approvals and certificates of Hirun spherical bearing include CRCC certificates for TJQZ series, National Production License for Industrial Products on Highway, CE certificate in conformity to EN1337.
