Structural Bearings
In order to change their field of application the elastomeric bearings can be combined with complementary bearing devices, such as a restrain system or a sliding system. The restrain type prevents movements in all horizontal directions. Sliding systems, with or without guides, allow movements bigger than the shear capacity in plane surfaces.
Since 2005 the European standard EN 1337-3 has applied to elastomeric bearings for architectural and civil-engineering applications. 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 bearings in accordance with this standard.
Experience shows that, under normal circumstances and with regular maintenance, Trelleborg’s structural bearings can function for decades.
