RJ Watson Spherical Bridge Bearings consist of a concave bearing plate, a convex mating plate, an upper sole plate and a lower masonry plate. Sliding surfaces consist of bonded PTFE mated to highly polished stainless steel. RJW Spherical Bearings are used to accommodate thermal, seismic and mechanical expansion and contraction and also provide multidirectional rotation for highway bridges, railway bridges and other civil engineering structures.
