Supply Dali round laminated rubber bearings

Circular plate is laminated rubber bearing rubber bearings improved. Wherein arranged between the layers of rubber and steel plate with a circular rubber bearings are identical, while the top surface of the holder is made of pure rubber, a spherical surface, the spherical center of the maximum thickness of the rubber 4-13mm, the spherical edge of 15mm, to fit into the 3% 4% slope aspect, the center beam and bearing contact surface tends to round laminated rubber bearing in the center. Beam end reaction force gradually spread through the spherical surface of the rubber sheet and spread beneath layers of rubber layer. In the rubber bearing underside circle diameter D = 2.5mm plus semicircular rubber ring, when the first bearing force from the bottom of the ring deformation compaction, adjust the underside force status, in order to improve or avoid bearing the underside Void phenomenon, even by force bearing underside
