Description of rubber bridge bearing:
Attaining maximum level of clients' satisfaction, our company has positioned itself as a well known supplier of Neoprene Bearing Pads.These are designed to be placed under pre-cast concrete beams & steel beam of buildings and bridges to provide a uniform transfer of load from beam to substructure.In addition, our Neoprene Bearing Pads cushion impact, shock and vibration.Our vendors design these pads at their state of the art machining facility by using quality approved materials and modern technology.
Features of rubber bridge bearing:
High impact strength
Smooth finish
Longer & durable life
Features of rubber bridge bearing:
(1)Quality materials including natural rubber, neoprene complying with AASHTO standards.
(2)Allow for expansions and contractions of precast steel structure of bridges.
(3)Capable to control load distribution, meanwhile accommodate thermal and end-beam rotational movements.
(4)Vibration, sounds and shocks isolation.
(5)Avoid excessive load eccentricity and edge compression.
(6)Simple but robust structure.
(7)Lower price than laminated elastomeric bearing.
(8)High cost effectiveness.

There are ten main types of bridges bearings are supplied to meet your different needs.Some specific designs are also available as your request.
Laminated elastomeric bearing is manufactured through the process of vulcanization and moulding to form a homogeneous unit with layers of steel plated embedded in.Comparing with plain elastomeric bearing, this one has higher vertical load capacity, excellent vibration and sound isolation.It is ideal for bridges with short span and flyovers, etc.
PTFE top elastomeric bearing, a variation of traditional laminated elastomeric bearing, features a layer of PTFE bonded to top surface of the bearing.In conjunction with lubricant in the dimples of PTFE, the bearing allows for excellent sliding movements with reduced friction coefficient.
Elastomeric bearing with steel plate is reinforced with outer steel plates vulcanized directly onto the surface of rubber pad.It can be manufactured with holes or pins for easy fastening.They are ideal for in-situ concrete structure, metal structures and anti-life device, etc.To suit your scheme, six types can be provided by our company.
Plain elastomeric bearing with the simplest structure among all bearing products is exclusively manufactured from natural rubber or neoprene rubber.It is considered to be a low cost choice for short span bridges, prefabricated structures, buildings as well as flyovers, etc.
Pot bearing, is the widest used type designed for structures using the incremental launching methods, highways and railways, etc.PTFE top elastomeric bearing is fitted in the steel pot plate to ease the sliding movements with the help of a stainless steel panel welded on top steel plate.
Spherical bridge bearing features its precision-machined steel plates with concave ad convex surfaces.And it can accommodate large movements and rotations in excess of +/- 0.03 radians.Spherical bridge bearings can be applied to structures with large turning angles, wide and curved bridges regardless of low temperatures even under -30ºC.
Disc bridge bearing features polyurethane disc with excellent chemical resistance, corrosion resistance regardless of various environmental influences.It can bear higher stress than traditional pot bearing and transfer shear forces owing to its threaded shear pin.
Lead rubber bearing, as its name implies, has a lead plug in the middle of the bearing that will assist the bearing to absorb earthquake-generated forces, extending the structure vibration period.In this way, lead rubber bearings protect buildings or structures from damages and severe deformations caused by earthquake.
High damping rubber bearing, manufactured from quality rubber with great damping ability and high durability, is also a seismic isolator similar to lead rubber bearing without the central lead plug.
Rocker bearings, with stainless steel pins are capable to absorb living load, constant load, compression and shear forces by providing stable movements and rotations.With high earthquake-proof property, it can be applied to areas with high seismic intensity up to 9 degrees.
Packaging for Bridge Rubber Bearings:
Plastic Film Wrapping: Each rubber bearing is individually wrapped in plastic film to protect it from moisture, dust, and physical damage during transit.
Palletization: The wrapped bearings are then placed on pallets for stability and ease of handling. Palletization also facilitates the use of forklifts and other materials handling equipment.
Strapping or Banding: To secure the bearings on the pallet, strapping or banding may be used to prevent shifting during transportation.
Transportation of Bridge Rubber Bearings:
Sea Freight Containers: For international shipments, sea freight is a common method due to the ability to handle large quantities and the cost-effectiveness for heavy and bulky goods like bridge rubber bearings.
Container Selection: Depending on the size and quantity of the bearings, appropriate container sizes (such as 20' or 40' standard containers) are chosen to optimize space and ensure safe transportation.
Container Loading: The palletized bearings are carefully loaded into the containers, often with additional securing measures like wooden blocks or braces to prevent movement within the container during sea transport.
Customization: Transport methods can be adjusted to meet customer requirements, including alternative modes of transport such as air freight or land transportation if sea freight is not suitable.
