The typical application of roller supports is in large bridges. In civil engineering, roller supports can be seen at one end of a bridge. A roller support cannot prevent translational movements in horizontal or lateral directions and any rotational movement but prevents vertical translations. [1] [5] Its reaction force is a single linear force ...
In earthquake engineering, a metallic roller bearing is a base isolation device which is intended for protection of various building and non-building structures against potentially damaging lateral impacts of strong earthquakes. This bearing support may be adapted, with certain precautions, as a seismic isolator to skyscrapers and buildings on ...
Flat surface bearings often consist of rollers and are mounted in a cage, which is then placed between the two flat surfaces; a common example is drawer-support hardware. Roller-element bearing for a shaft use bearing balls in a groove designed to recirculate them from one end to the other as the bearing moves; as such, they are called linear ...
Cross-sections of continuously rolled structural shapes, showing the change induced by each rolling mill. Structural shape rolling, also known as shape rolling and profile rolling, [1] is the rolling and roll forming of structural shapes by passing them through a rolling mill to bend or deform the workpiece to a desired shape while maintaining a constant cross-section.
Commercial buildings will often have complex pre-fabricated components. These include: elevators, windows, cabinets, air handling units, generators, appliances and cooling towers. These pieces of equipment often require close coordination to ensure that they receive the correct power, fuel, water and structural support.
A simple support (pin or roller) is equivalent to a point force on the beam which is adjusted in such a way as to fix the position of the beam at that point. A fixed support or clamp, is equivalent to the combination of a point force and a point torque which is adjusted in such a way as to fix both the position and slope of the beam at that point.

Another type of bridge bearing is the mechanical bridge bearing. There are several types of mechanical bridge bearing, such as the pinned bearing, which in turn includes specific types such as the rocker bearing, and the roller bearing. Another type of mechanical bearing is the fixed bearing, which allows rotation, but not other forms of movement.
