spreiz

Spreiz is a German term built from the verb spreizen, meaning to spread apart or widen. As a noun, Spreiz is primarily found in technical contexts and appears in compounds such as Spreizung (the act or extent of spreading), Spreizwerkzeug (a tool designed to spread apart components), or Spreizklammern (spreading clamps). The related verb spreizen describes actions that create space, widen gaps, or separate parts in a controlled way.

In mechanical engineering and industrial assembly, a Spreiz refers to the mechanical action of forcing two halves or elements away from each other. This is typically achieved with wedges, springs, hydraulic or pneumatic force, or other transmitting mechanisms. Spreading devices are used to facilitate assembly, disassembly, or maintenance tasks, for example when inserting bearings, separating flanges, or preparing joints without inducing unwanted deformation.

In construction and maintenance, the concept of spreading is employed in procedures that require controlled expansion to fit parts or to create working clearances. The term often appears in manuals and specifications that describe equipment designed to apply lateral force evenly and steadily.

Other domains may reference the general idea of spreading with related terms, though the standalone noun Spreiz is less common outside technical or specialized discourse. Related concepts include Spreizung (spreading action or extent) and Spreizer (spreader device).
