Import New Design Spherical Bridge Bearing — Buy in wholesale FOB from Supplier in Viet Nam

Vinh Hung Tcc Jsc. manufactures a new design spherical bridge bearing in Viet Nam using high‑strength steel of grade Q345 or equivalent, combined with a PTFE sliding surface and EPDM rubber components. The bearing incorporates a PTFE lower plate, a polished hard‑chromium convex calotte, and a secondary PTFE plate recessed into the upper surface, all supported by a stainless‑steel sheet to minimise friction. Protective coatings include two‑component epoxy, polyurethane paint, hot‑dip galvanisation to ASTM A123, and an Al‑Mg spray coating (5% Al, 95% Mg) that has passed a 6000‑hour salt‑spray test. The design allows a rotary angle of at least 0.015 rad in every direction, meeting TCVN 11823, AASHTO LRFD, ASTM D5977 and EN 1337 standards.

These bearings are typical of the bridge‑bearing market where steel housings with PTFE or composite sliding layers are standard for durability and low friction. The use of EPDM rubber components provides additional resilience against dynamic loads, while the hard‑chromium plating on the calotte ensures wear resistance. Corrosion protection methods such as epoxy, polyurethane and Al‑Mg spray coatings are common industry practices that extend service life to around a century under aggressive environmental conditions. The product is positioned for projects that require reliable rotation and translation accommodation, aligning with the technical expectations of modern civil‑engineering specifications.

The bearings are intended for highway bridges, railway viaducts and other large‑span infrastructure where heavy loads and thermal movements occur. Primary buyers are civil‑engineering contractors, bridge designers and infrastructure developers who need components that comply with recognised international standards. Trade terms such as minimum order quantity, incoterms and packaging details are not disclosed in the listing; potential importers should confirm these points directly with Vinh Hung Tcc Jsc. before placing an order.
