Structural bearings   Concept Principle mageba RESTON®DISC bearings are uniquely defined by their Polyether-Urethane (PU) rotational element which is placed between two plates, the upper bearing plate and the lower bearing plate. The rotational element’s elasticity enables tilting movements of the upper bearing plate around any horizontal axis. The rotational capacity is facilitated by a “V” shaped groove along the exterior contour of the disc. A shear pin placed in the centre of the rotational element absorbs the horizontal forces and keeps the upper and lower bearing plates in position. The...

Structural bearings   Properties Materials The following high-quality materials are used in the manufacture of RESTON®DISC bearings: Due to its high compressive strength, the rotational element requires no confinement. Dimensioning of the PU disc is based on the behaviour of a linear elastic material, unrestrained laterally at its top and bottom surfaces. The unconfined disc accommodates rotation by the differential deflection of the PU element. The horizontal structural loads are transmitted by a steel pin located at the centre of the disc. It is designed to be fully functional at up to twice...
