Heavy Duty Fixed Pot Bridge Isolation Bearing for Structures
AVIDA pot bearings ensure the transfer of loads between a structure’s superstructure and its sub-structure. Meanwhile they can accommodate rotation and movements of the superstructure. AVIDA POT bearings are generally suitable for the use in any type of structure, and can be subjected to low or high loading and frequent movements and rotation.
AVIDA pot bearings are designed and manufactured acc. to customer requirements, in accordance with relevant standards such as EN 1337, AASHTO, BS5400 or AS 5100.a.
Structure
Rubber Physical&Mechanical Properties
The austenitic steel used for sliding surfaces is X5CrNiMo17-12-2 in accordance with EN 10088-2 1.4401 with a minimum thickness of 1.5 mm. The roughness is Ry5i ≤ 1 μm, The hardness ≥ 150 HV1 and ≤ 220 HV1.
AVIDA uses only virgin PTFE without regenerated or filler materials.
The minimum thickness for bonded PTFE is 1.5 mm and varies in according with the bearings size and type.
The minimum thickness of recessed PTFE is 4.5 mm and varies in according with the bearings size.
Different Types Bridge Bearings
Features
1, With low-profile yet high loading capability over 50,000 KN.
2, Maximized shearing strength of elastomer pad through the method of encasing it in the steel pot.
3, Allow for large rotations ranging from 0 to 0.03 rad.
4, Low friction coefficient between 1% and 3%.
5, Excellent fatigue, impact and aging resistance of the layer of PTFE.
6, All the metallic parts are protected against corrosion by galvanization and epoxy painting according to EN 1337-9 (other protective coatings are available as your requirements).
7, Complying with BS EN-1337, KS4424, AASHO, ISO or other custom standards.
