ERGOFLON SPHERE type devices are spherical bearings, which allow rotations up to +/- 0.055rad around any horizontal axis through the coupling of a convex surface and a concave surface with the interposition of a low friction surface made with PTFE (or different material) – stainless steel coupling.
The bearings are designed to be used as hinges (fixed type) or one-way (unidirectional type) or two-way (multidirectional type).
The connection to the structure can be made, depending on the nature and extent of the actions, with mechanical anchorages or by gluing with resin.
