Guided Sliding Pot Bearing

1. PRODUCT OVERVIEW
VHB pot bearing made by Vinh Hung Investment and Production Company Limited (Vinh Hung IP) are in compliance with standards (TCVN
10268:2014, AASHTO LRFD: 2007, Section 18, ASTM D5212â??03, BS5400, EN1337, KS4420).
VHB pot bearing is capable of withstanding high loads, displacements and wide angle rotation.
This type of bearing is suitable for middle-range span structure, continuous bridge structure etc.
with a load capacity of 60000kN or above depending on projects requirements. VHB pot bearing has well-shaped structure, superior
design, which is convenient for installation and maintenance during operation

PRODUCT CHARACTERISTICS
VHB pot bearing is comprised of 4 main parts: top plate, piston, pot plate and elastomeric pad. The elastomeric pad is placed inside of pot plate, under the pressure of the load, the elastomeric pad experiences
the temporary deformation inside the pot plate volume, it is capable of withstanding the forces and allows the movement as well as rotation along horizontal axis. Piston and pot plate work as the connecting parts
between the structures. Besides, the plus guiding bar can be designed to limit or allow the movements as required from the structures.
Pot bearing is divided into 2 main types: Fixed pot
bearing and sliding pot bearing.
Fixed pot bearing: The bearing only allows the head of structure to have rotary movement and transfers the pressure through a fixed point.
Sliding pot bearing: This type of bearing, including free sliding bearing and guided sliding bearing, allows the head to have both rotary movements and transversally or multidirectional movements.
To ensure the long-life durability, VHB pot bearing is protected against corrosion by the following methods
two-component epoxy coat, PU-based painting (Polyurethane), hot dip galvanization according to ASTM A123 standards and especially the Al Mg spraying method (at the ratio of 5% Al and 95% Mg) which ensures the anti-corrosion durability of up to 100 years, proven by salt-spraying test in 6000 hours (8-hour dry-wet cycle repetition) under ASTM B117

Pot Bearings are divided into 2 main types: Fixed pot bearings and sliding pot bearings.
Fixed pot bearings: The bearings only allows the head of structure to have rotary movement and transfer the pressure through a fixed point.
Sliding pot bearings: This type of bearings includes Free sliding bearings and Guide sliding bearings, which allows the dead to have both rotary movements and unidirectional or multidirectional movements.
To ensure the long-life durability, VHB pot bearings are protected against corrosion by the following methods: painting with two-component epoxy coat, PU-based painting (Polyurethane), hot-dip galvanization according to ASTM A123 standards and especially the Al-Mg coating spraying method (at the ratio of 5% Al and 95% Mg) which ensures the anti-corrosion durability of up to 100 years, this method is proved by
the salt-spraying test in 6000 hours.

The bearings we have defined so far are the basic types, which constant feature is the fact that they allow all-ways movements and rotation.

However, movements can be limited in one or all ways, thus obtaining guided or fixed bearings, respectively. In the first case -guided bearings- the restriction is obtained by means of guides parallel to the supporting axe that allows movement.

To make friction as low as possible, PTFE and stainless steel sheets are welded to the guides.
