Introduction
WANBAO pot bearings ensure the transfer of loads between a structure’s superstructure and its sub-structure. They also accommodate rotation and movements of the superstructure. WANBAO POT bearings are generally suitable for use in any type of structure, and can be subjected to low or high loading and frequent movements and rotation.
WANBAO pot bearings are designed and manufactured acc. to customer requirements, in accordance with relevant standards such as EN 1337, AASHTO, BS5400 and AS 5100.
Quality guarantee
WANBAO pot bearings have been used successfully for more than 1000 bridges over a period of over 30 years in China and abroad.
Quality and durability of bearings are ensured by:
Ø Qualified and experienced personnel
Ø Cleverly designed and reliable components
Ø High-quality materials (PTFE-disc with a minimum thickness of 5 mm, DU-strips with bronze pieces, well controlled silicone oil, etc.)
Ø High quality standard (certified to ISO9001)
Ø QA certified working and manufacturing practice
