vägglager
Vägglager, or wall bearing, is a term used in Swedish engineering to describe a bearing assembly that is mounted in or on a wall to transmit load or support a rotating shaft. In structural engineering, vägglager refer to supports that anchor beams, lintels, or arches to a wall, transferring vertical loads and moments into the structural wall through fixed brackets, corbels, or embedded anchors. In mechanical applications, a vägglager denotes a bearing unit mounted in a wall or in a wall-mounted housing to support a shaft or axis; this type may involve flange bearings, sleeve bearings, or ball bearings housed within a wall flange.
Design and installation considerations include alignment accuracy, load type (radial and axial), moment transmission, and service
Materials commonly used are steel or bronze for bearing surfaces, with concrete, steel brackets, or masonry
