A flange is a typically ring-shaped component used for connecting, fastening, or supporting machine elements. It enables a detachable, form-fitting, and force-locking connection between two components, frequently using screws. Flanges are employed in mechanical engineering, plant construction, drive technology, as well as in piping and connection systems.
Typically, a flange has a flat or specially machined contact surface as well as holes for screws or bolts. This allows components to be precisely aligned and securely fixed. Depending on the application, a flange can absorb additional forces, transmit torques, or position components axially.
In drive technology, such as with ball screw drives or bearing units, the flange is frequently attached to nuts or housings. There it serves to fasten the nut to the machine structure and enables simple assembly as well as quick replacement.
Flanges are manufactured from different materials, for example steel, stainless steel, aluminum, or cast iron, depending on load, environmental conditions, and weight specifications. The design also varies considerably, such as round flanges, square flanges, or special flanges.
In summary, a flange is a universal connecting element that ensures a stable, precise, and detachable connection between components and is indispensable in numerous technical applications.
