Elastomeric bearings AGOM E-Link AGOM elastomeric bearings are built to withstand loads and simultaneous deformation in any direction, while also allowing for minor rotations in any of the bearing's axes. AGOM E-Link bearings can be made entirely of rubber or can be reinforced with special sheet steel to increase capacity and transversal strength. Bearings can also be produced with special anchor plates or with sliding surfaces to improve the structure's displacement capacity. This kind of bearing can withstand vertical loads of up to 22000 kN. E-Link F plain pad bearings AGOM E-Link F...

E-Link Type C3 Elastomeric bearing with two outer plates with threaded holes for use on metal structures, or as an anti-lift device; in the latter case, suitable anchor bars to withstand the design loads must be inserted into the support. E-Link Type C4 Elastomeric bearing with external plates and pins that connect to suitable steel counterplates in order to secure the bearing to the structure and to allow an easy replacement. E-Link Type C4E Elastomeric bearing with external plates and an upper pin that connect to a suitable steel counterplate in order to secure the bearing to the...

E-Link Type E Elastomeric bearing with a PTFE sheet embedded in the vulcanised top plate, to reduce the coefficient of friction with the welded stainless steel on the upper movable plate: it’s a support designed to allow free movement in the longitudinal and transverse directions. E-Link Type EG Elastomeric bearing with a guided sliding plate: it allows movements in the longitudinal direction, while preventing them in the transverse direction by means of steel guides. A sheet of PTFE is embedded in the vulcanized top plate, to reduce the coefficient of friction with the stainless steel,...

Materials Rubber compound The elastomer used in the machining process can be polychloroprene or neoprene (CR), natural rubber (NR) or SBR according to the required specifications. The mechanical properties of the elastomer are shown in the tables below. AGOM has an in-house research and development laboratory suitable for performing all the required quality controls of the compounds used in the production process. The AGOM quality control department controls each batch and certifies compliance with the standards, as provided by the required international regulations. (a) = not specified (b)...

(a) = not specified (b) = agreed upon request Steel for reinforcement plates Reinforcement plates and outer plates are made with steel according to the standard EN 10025. Austenitic steel sheet The austenitic steel used for sliding surfaces is X5CrNiMo17-12-2 in accordance with EN 10088-2 1.4401 with a minimum thickness of 1.5 mm. The roughness is Ry5i < 1 pm. The hardness is > 150 HV1 and < 220 HV. PTFE AGOM uses only virgin PTFE without regenerated or filler materials. The minimum thickness for bonded PTFE is 1.5 mm. The minimum thickness of recessed PTFE is 4.5 mm and varies according...

Bearing fixing Generally, E-Link bearings with external steel anchor plates are provided with anchor bars suitable for attachment to the lower and upper parts of the structure. In the case of prefabricated structures, bearings can be provided with an upper pin and a counterplate to be embedded in the concrete; in the case of steel beams, bearings can be supplied with an upper pin and / or fixing screws. To account for the angle of inclination of the superstructure, the top plate of the elastomeric support can be made according to the drawing, taking into account the equivalent angle of...

Comprehensive Labelling All the bearings with outer steel plates are provided with a metal label detailing the proprieties of the bearings: • bearing type • maximum vertical and horizontal loads • rotation • order number • date of manufacture • CE Mark The top face of the bearing gives information on the type of the bearing, the direction of the axis of the bridge, the presetting (if any), the position. Furthermore all E-Link bearings are provided with a non-fading mark directly molded on the rubber outlining the properties of the bearing: • international standards • order number • date of...

Guidelines for the design of a structure with AGOM E-Link bearings In this section a simple guideline for the design of a structure equipped with AGOM bearing is presented. The design procedure is summarized in the following steps: 1. Selection of the structure static link scheme (all simple elastomeric bearings or fixed and movable elastomeric bearings). Calculation of the loads (vertical and horizontal) on the bearings according to the fixing scheme. Calculation of the bearing rotations and movements. Insertion of all the bearing design data into the bearing design table (example table...
