Get Instant Quality Info! Our bearing range includes steel and plastic housed bearings for all types of Conveyor Rollers as well as Bearings for Overhead Conveyors which include Crowded Race, Sintered Iron Caged and Ribbon Caged construction.


A bridge bearing is a component of a bridge which typically provides a resting surface between bridge piers and the bridge deck.

The purpose of a bearing is to allow controlled movement and thereby reduce the stresses involved. Bridge bearings also makes rooms for relative movements between superstructure and substructure, for instance, rotation movements and translational movements in horizontal and transverse direction. Bearing used in the construction of bridge structure is divided into two major categories namely expansion bearings and fixed bearings.


AGOM elastomeric bearings, called E-Link, are built to withstand loads and simultaneous deformation in any direction, while allowing for minor rotations in any of the bearing’s axes. E-Link bearings can be made entirely of rubber (natural or synthetic) or can be reinforced with special sheet steel to increase capacity and transversal strength. Bearing is a component of a bridge which typically locates between bridge substructures and superstructures, playing an important role in the force transmission and in accommodating the deformation caused by temperature variation and the earthquake.


Bridge bearing, as connection component, can provide a resting surface between bridge and bridge piers. And the purpose of bridge bearing is to transfer forces from the superstructure to the substructure or reduce the ground vibration to the superstructure. The bridge modelerlocates bearing linksdirectly below the girder web.

To model a different bearing layout, delete the links automatically create then, outside the bridge modeler, manually create links as desired. Bearing pads are used extensively in bridge structure – Pre-stressed and Pre-cast concrete buildings. Spherical bridge bearing features its precision-machined steel plates with concave ad convex surfaces. Besides the functional requirements, the standard describes the design rules, the material properties, the production tolerances and the acceptance tests. Trelleborg designs and manufactures elastomeric bridge bearings in accordance with this standard.


Bridge bearings are devices for transferring loads and movements from the deck to the substructure and foundations. In highway bridge bearings movements are accommodated by the basic mechanisms of internal deformation (elastomeric), sliding (PTFE), or rolling. A large variety of bearings have evolved using various combinations of these mechanisms.


We produce bridge bearings including elastomeric bearing , pot bearing , spherical bearing and seismic isolation bearing. With over years of combined experience in the Agriculture and Automotive spare parts industry, we have the knowledge and skills to find what you need. Bridge bearings support structures at a constant elevation, carrying forces from the superstructure into the substructure and allowing necessary superstructure motions to take place. The same principles apply to all types of structure where forces are exerted.


Movement could be thermal expansion or contraction, or movement from other sources such as seismic activity. Pot bearings are used as another way of compensating for differential movements in various types of structures, and in particular in the bridge engineering sector. They are designed in such a way that they permit vibrations, movements and rotations caused by earthquakes, traffic loads or climatic influences, while simultaneously protecting the structure against damage. Bridge bearings from VSL-CTT are designed and manufactured in accordance with the main codes and specifications. Any other specifications may also be accommodated.


Dynamic pot bearing – including fixed pot bearings are the new generation of bridge bearings designed to meet the demands of today’s complex bridge structures. They carry a vertical load by compression on an elastomeric pad confined in a steel cylinder and which accommodates rotations by deformations of the disc.

Due to years experience for making the bridge bearings , we can also accept the customized bridge bearings. These bearings are devices that must perform multiple functions in the same time. Modification is then done outside of the bridge modeler. This tutorial will follow a two-span continuous reinforced-concrete box-girder bridge with four web sections, supported by two bearings at each substructure location. Three of the steel plate girder bridges on the Dulles Metro Line Project featured Disktron Bearings which ranged from 2kips to 9kips in vertical load capacity.


The rotational capacity of these bearings was 0. PTFE) material (lower component), with or without special components (steel guide bars and bottom plate).
