Description
Product overview
mageba RESTON SPHERICAL bridge and structural bearings transfer vertical loads between a structure's superstructure and substructure while accommodating rotations about every axis and translations in every direction. A convex curved element slides on a matching concave surface to transmit vertical forces and permit the required movements. Designed for compact installation heights, these bearings offer long service life and are maintenance-free.
Key features
Operating principle
RESTON SPHERICAL bearings use a convex sliding element running on a matching concave surface. Vertical loads are transferred through the contact interface while the geometry allows rotation about any horizontal axis and movements in all directions. The design supports sliding both on planar and curved sliding surfaces.
Applications
Suitable for bridges and structures requiring medium to high load transfer combined with significant cumulative sliding and rotation, for example suspension and long-span bridges subject to wind and thermal movements. The high-strength sliding material enables a reduced bearing footprint where installation space is limited.
