Railway rail transit bridge ball bearings - TGPZ series

The Three Bridges (Urban Rail) Tong (2008) 8060 series bearings are suitable for bridge structures such as simply supported beams, continuous beams, arch bridges, etc. in urban rail transit engineering (subway, light rail, etc.) (in areas where the design seismic peak acceleration Ag ≤ 0.3g). Sanqiao (Urban Rail) Tong (2008) 8060-C1 is used for designing seismic peak acceleration Ag ≤ 0.15g areas;
