Double Curvature Steel Bearing

Double curvature steel bearing is designed to allow the flexible rotation along the longitudinal direction and limited rotation along the transversal direction due to different radius. The small rotation radius along the longitudinal direction leads to the flexible rotation with larger angle while the big rotation radius along the transversal direction to larger rotating friction and angle. The vertical load normally varies from 1500kN to 3000kN and itcan be designed individually for higher load. This product is mainly applied to railway bridge structures.

The approval and certificate of Hirundouble curvature steel bearing includes CRCC certificates for SQMZ series
