1, can carry vertical load;
2, with anti-vertical tension performance guarantee when the upper and lower vertical seismic structure is not out of line;
3, the performance level of force with anti ensure not out of line when the horizontal seismic structure;
4, can be adapted to the radial and circumferential displacement request;
5, can be adapted to any direction angle request;
6, damping bearings with outstanding damping performance;
7, through the spherical bearing force transmission, does not appear necking force acting on the structure of the reaction force under uniform;
8, the carrier does not have to rubber under pressure, there is no impact on the aging of rubber bearings, and long service life. Guangzhou Steel
