Bridge Bearings Suppliers, UAE
Bridge bearings in the UAE are the elastomeric, pot and spherical bearings that carry flyover, interchange, viaduct and footbridge decks onto their piers while letting them move and rotate. This page explains each bearing type, which design standards UAE consultants specify as of 2026, how heat and coastal salt affect bearing life, and what to send the bridge bearing suppliers listed below to get a firm offer.

What are bridge bearings, and which types are used in the UAE?
A bridge bearing transfers the deck's vertical load and horizontal forces to the pier or abutment while allowing the movement and rotation the designer has assumed. The category belongs to bridge and tunnel products in the UAE, and UAE road and rail structures mostly use three families: laminated elastomeric bearings, pot bearings and spherical bearings, each made fixed, guided or free.
| Bearing type | How it works | Typical UAE use | Key specification |
|---|---|---|---|
| Plain elastomeric pad | Rubber pad deforms in shear and compression | Short spans, precast beam seats, footbridges | Load, shear movement, elastomer grade |
| Laminated elastomeric bearing | Rubber layers bonded to steel plates; may carry a PTFE sliding top | Precast beam and box girder flyovers, car park ramps | Plan size, number of layers, rotation, sliding element if movement is large |
| Pot bearing | Elastomer disc confined in a steel pot, with a PTFE and stainless sliding plate for guided or free types | Continuous box girders, interchange ramps, viaducts with heavy reactions | Vertical and horizontal load, rotation, movement in each axis |
| Spherical bearing | Curved sliding surfaces allow large rotation with low resistance | Long-span steel and concrete decks, curved ramps, rail viaducts | Rotation capacity, sliding material, friction, load |
| Seismic isolator or damper | Lead rubber bearings, curved surface sliders and dampers that limit earthquake forces | Where the design calls for seismic isolation | Device type and performance tested to the named standard |
Bearings are ordered in the same package as the deck movement joints, so read alongside bridge expansion joints in the UAE, which must use the same movement and temperature figures. Cast-in-place decks need bridge formwork systems designed around the bearing and plinth levels, and precast beams from precast concrete suppliers sit directly on elastomeric bearings. Machinery anti-vibration pads are a different product, listed under rubber mounts and vibration dampers.
How do UAE heat, salt and sand affect bridge bearings?
UAE conditions affect bridge bearings in three ways: a large temperature range drives daily deck movement, chlorides corrode exposed steel near the coast, and sand and debris collect around bearings and sliding surfaces. Getting these into the specification costs little compared with replacing bearings under traffic.
- Temperature range. The sliding range of guided and free bearings must cover the design temperature range in the project specification plus creep and shrinkage on concrete decks. Ask the supplier to show the movement calculation, not just the catalogue range.
- Elastomer ageing. High sun and ozone age exposed rubber. Ask for the compound grade and ageing test data, and keep bearings shaded by the deck and diaphragm.
- Corrosion. For creek, lagoon and coastal crossings in Dubai, Abu Dhabi and the northern emirates, specify a coating system for marine exposure, stainless steel mating surfaces for sliding plates and protected anchor bolts.
- Sand and dirt. Fit dust skirts or bellows over sliding surfaces and keep the bearing shelf drained; packed sand stops a free bearing from sliding.
- Access. Leave room and jacking points for future replacement. EN 1337 includes parts on inspection and maintenance and on transport, storage and installation.
Which standards and approvals apply to bridge bearings in the UAE?
UAE bridge bearings are approved against the design standard named in the contract, usually the EN 1337 series or the AASHTO specifications, and through consultant review of calculations, drawings and test reports. There is no single national certificate for bearings. Checked October 2026; confirm the editions in your project specification.
| Requirement | Applies to | Body |
|---|---|---|
| EN 1337-1 general design rules; parts for sliding elements (2), elastomeric (3), pot (5) and spherical and cylindrical PTFE bearings (7) | Bearings on projects designed to European standards | CEN, published in the UK by BSI |
| AASHTO LRFD Bridge Design Specifications, 10th edition (2024) | Bearing design on projects designed to AASHTO | AASHTO |
| AASHTO M 251, plain and laminated elastomeric bridge bearings | Material and fabrication of elastomeric bearings on AASHTO projects | AASHTO |
| EN 15129 anti-seismic devices | Isolators and dampers where specified | CEN / BSI |
| Abu Dhabi Guidelines for Road Engineering Design, update approved July 2022 | Road design in Abu Dhabi emirate | Abu Dhabi Quality and Conformity Council, with the Department of Municipalities and Transport |
What the consultant will ask for
Expect to submit a bearing schedule with loads, movements and rotations per bearing, design calculations, general arrangement drawings, material certificates and type or production test reports for the bearing type and size. Many UAE specifications also ask for load testing of a sample of production bearings, witnessed by the consultant or a third party. Check whether the specification follows European or American rules before you request prices, because the tests and the paperwork differ.
How do you choose a bridge bearing supplier in the UAE?
Choose a bridge bearing supplier in the UAE that will design the bearings to your standard, hold the test evidence for that type and size, and support installation on site. Bridge bearings are made to order, so the manufacturer matters more than the local trading company.
Most bearings for UAE projects are made in Europe or Asia and sold through UAE agents or regional offices; simple elastomeric pads are also made in the region. A stockist rarely helps beyond standard pads, because each bearing is sized for one structure.
- Who manufactures the bearing, and is the UAE company an authorised agent with engineering support?
- Which standard is the bearing designed and tested to, and do the test reports cover the same type and load range?
- Who prepares calculations and drawings, and how many submittal rounds are allowed for in the price?
- Is installation supervision included, along with grouting instructions and temporary transport locks?
- What corrosion protection system and sliding material are offered, and what is the expected service life?

What affects the price and lead time of bridge bearings in the UAE?
Bridge bearing prices in the UAE depend on load, movement and rotation, the bearing type and the testing required. Lead time is design approval plus manufacture plus shipping, so bearings must be ordered well before the deck programme needs them.
- Type and size: pot and spherical bearings for heavy reactions cost far more than laminated elastomeric bearings.
- Movement: long sliding ranges need larger sliding plates and guides.
- Testing: project-specific production tests and third-party witnessing add cost and weeks.
- Protection: marine-grade coatings and stainless components raise price on coastal crossings.
- Logistics: imported bearings land at Jebel Ali or Khalifa Port; large units need careful handling and storage on site.
