Zylinderende

Zylinderende is a term used in engineering to denote the end surface of a cylindrical object. The word combines Zylinder (cylinder) with Ende (end) and appears in German- and Dutch-language technical texts, especially in diagrams and component specifications. In most contexts, a cylinder has two ends: the end face at one extremity of the axis and the opposite end face. The end can be simply a flat end or may be formed into an end cap or cylinder head, sometimes incorporating mounting bosses, seals, or ports.

Geometric properties: For a cylinder of radius r and height h, the end face is a circle with area pi r^2. The end surfaces are perpendicular to the cylinder axis, and their geometry must satisfy tolerances to ensure proper sealing and alignment.

Applications: The term is commonly encountered in mechanical engineering, hydraulic and pneumatic cylinders, and piston engines. In diagrams, labels such as Zylinderende may indicate features located at the ends, such as end caps, mounting surfaces, or seal grooves. In Dutch and German practice, more specific terms like cilinderkop (cylinder head) or cilinderbodem (cylinder base) / Zylinderkopf / Zylinderboden may be used depending on context.

Variations and standards: The exact definition of what counts as the “end” can vary by design and standard. Engineers specify permissible flatness, perpendicularity, surface finish, and any features on the end face to guarantee proper assembly.
