They permit rotation at the bearing point due to deflection or misalignment. They absorb vibration and prevent sound transfer, while reducing the destructive action of vibration between movable and stationary members. They also provide for movement caused by normal expansion and contraction.

1. Product Overview VSR Elastomeric Bearings made by Vinh Hung investment and production Co., Ltd (Vinh Hung IP) are in compliance with TCVN 10308: 2014, AASHTO LRFD Section 18, AASHTO M 251 96 (2011), BS5400, EN1337, KSF4420 VSR Elastomeric Bearings have been used in road bridge constructions, with a maximum load of 5000kN. 2 PRODUCT CHARACTERISTIC Elastomeric bearings are composed of rubber and steel plates which are chemically bonded through vulcanization. The thickness of the bearing is calculated to ensure the load, displacement and rotation as the requirement. Elastomeric bearings are simple geometric structures, bringing convenience during the installation, operation and maintenance. In addition, this type of bearing provides high resistance of vibrations impacted to the bridge span structures and piers.
1. Product Overview VHC spherical Bearings/ Bridge bearing manufactured by Vinh Hung Investment and Production Company Limited (Vinh Hung IP) are capable of withstanding the high loads and movements suitable for structures requiring the rotary angle equal or bigger than 0.015 rad in all directions. VHC spherical bearings are designed and manufactured according to current standards such as: TCVN 11823, AASHTO LRFD, ASTM D5977, EN 1337, 2. PRODUCT CHARACTERISTICS VHC spherical bearings/ bridge bearing possesses a bottom plate (6) which has a PTFE sliding plate (4) on it is upper curved surface. A convex calotte (5) is placed on top of this, which, thanks to it is polished hard-chromium plated surface, can slide within the lower part with low friction, thus facilitating rotations about every axis. A second sliding plate of PTFE (4) is recessed into the upper surface of the calotte. Together with the upper plate (2) above it, this accommodates longitudinal and/or transverse sliding movements of the superstructure, if required. To reduce sliding resistance to a minimum, the lower surface of the top plate features a polished stainless steel sheet. In the case of bearings which should allow movement along one axis only, the direction of movement is controlled by guiding bars (3). In the case of fixed bearings, the top plate does not have a stainless steel sheet. The bearing is connected to the superstructure and the substructure by means of anchor dowels (1) or threaded sleeves (depending on design), or alternatively by means of separate anchor plates with shear studs. To ensure the long-life durability, VHC spherical bearings are protected against corrosion by the following methods: coating with two-component epoxy, PU-based painting (Polyurethane), hot-dip galvanization according to ASTM A123 standards and especially the Al-Mg spray coating method (at the ratio of 5% Al and 95% Mg) which ensure the anti-corrosion durability of up to 100 years, this method is proved by the salt-spraying test in 6000 hours (8-hour dry-wet cycle) according to ASTM B117
Elastomeric bearings reinforced internally with one or more steel plates, chemically bonded during vulcanisation are called laminatid elastomeric bearings. Elastomeric bearings permit a smooth and uniform transfer of loads from beams to substructure and also allow beam rotations at the point of support due to deflection of beam under loading. They further allow lateral and longitudinal movement of beams caused by thermal forces. Elastomeric bearings have no moving parts and thermal expansion and contractions are supported by shear capacity of elastomers. There is no sliding motion between bearing and beam or between bearing and abutment.

PTFE Bridge Bearing Plate The PTFE bridge bearings plate is typically made of PTFE (Polytetrafluoroethylene), a high-performance polymer known for its low friction, excellent chemical resistance, and durability. PTFE is chosen for bridge bearing plates because of its ability to withstand heavy loads and environmental conditions. As a leading PTFE bridge bearings supplier, we select PTFE for its exceptional capacity to withstand heavy loads and environmental conditions, making it the ideal choice for bridge construction.

Piston and pot plate work as the connecting parts between the structures. Besides, the plus guiding part can be designed to limit or allow the movements as required from the structures. 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.
