Rubber Neoprene Laminated Elastomeric Bearing Pad

Structure and performance of Elastomeric Laminated Bearings
Types of bearing pads:
1.PLAIN BEARING(Non-reinforced elastomeric bearing)
Non-reinforced elastomeric bearing, also called plain elastomeric bearing, is the common and economical type of elastomeric bearing. It is manufactured from high quality nature rubber or neoprene rubber to meet AASHTO and many other standards, then molded to any required shape.

2.LAMINATED ELASTOMERIC BEARING PAD
Elastomeric Laminated Bearings is sulfurized and stuck gether by several layers of rubber sheet and thin steel plate. It has sufficient vertical rigidity, and can reliably transfer the counterforce on the upper structures to pier platform; it has fine elasticity, and can adapt to the rotation of beam end; it has great shearing deformation capacity, and can satisfy the horizontal displacement of the upper structures.
3.PTFE ELASTOMERIC BEARING PAD- Freely Sliding
Adhere a layer of 1.5mm to 3mm thick polytetrafluoroethylene plate on the surface of the above Elastomeric Laminated Bearings, and polytetrafluoroethylene sliding Elastomeric Laminated Bearing is formed. Besides vertical rigidity and elasticdeformation, able to endure vertical load and suit to the rotation of beam end, the beam end can freely slide on the surface of the tetrafluoro plate due to the low friction coefficient of the polytetrafluoroethylene plate, and the horizontal displacement is not limited; it
specially suit to bridges with medium or low load and large displancement.





Shape and size
Rectangular--100X100X14mm to 700X700X200mm in common, can be customized
Round --100mm to 1000mm in common, can be customized

C. EPDM Rubber bearing (applicable temperature -40~60°C )

Applicability of Elastomeric Laminated Bearings

General Elastomeric Laminated Bearing suits to bridges with span less than 30m and small displacement. Different flat shape suits to different bridge span structures: orthogonal bridges adopt rectangular bearing; curvilinear bridges, obique crossing bridges and cylindrical pier bridges adopt circular bearing.

Tetrafluoro Elastomeric Laminated Bearing suits to bridges with large span, several spans in continuous, with simply supported beam and continuous plates strutures, and large displacement. It can still be used as the sliding block in pushing of continuous beam and cross sliding of T-shaped beam. 

Quality test of Elastomeric Laminated Bearings:
If required by the client,full-scale factory production control testing can be carries out.
or we can supply with independent 3rd party testing. for special projects,customised testing can also be performed if requested by the client.(also our factory will supply free sample for you)
Customer Support
Our product specialists will be glad to advise you is selection of the optimal solution for your project,and to provide you with a quotation.
