bottenstopp

Bottenstopp, translating roughly to "bottom stop" or "end stop" in English, is a generic term used in engineering and design to describe a component that prevents movement beyond a defined lower limit of travel. The function is to establish an end position, absorb impact, and protect mechanisms from overtravel, wear, or damage. Because it is a broad concept, the exact form and specification vary by application.

Common implementations rely on mechanical contact with a fixed surface or a cushioning element housed at the bottom of a guide, drawer, slide, or frame. Materials range from hard plastics such as nylon or acetal to rubber, metal, or composite substances. Shapes include cylindrical pins, discs, domes, or modular blocks, and they may be fixed, adjustable, or spring-loaded.

Applications include linear motion systems in machinery and automation, where bottenstopp defines the minimum travel for slides or pistons; in furniture and cabinetry to limit closing and reduce noise or damage; and in consumer products to provide impact protection at the base.

Design considerations include load and wear, impact energy, environmental conditions (temperature, chemicals), and compatibility with mating surfaces. Installation may require screws, bolts, adhesive, press-fit, or magnetic mounting; alignment and preload are important for consistent function. Regular inspection or replacement is advised when wear or deformation is evident.

Although the term is Swedish, the concept is widely used in end-stop design, bumper assemblies, and footings. Related terms include end stop, limiter, bumper, and stopper.
