Übermaßlaufbuchse

Übermaßlaufbuchse is a German term that translates to "oversize bearing bush" or "oversize sleeve bearing" in English. It refers to a type of bearing component that is manufactured to be larger than the standard or original size. This intentional increase in diameter is typically done to compensate for wear, damage, or dimensional inaccuracies in the mating shaft or housing.

These bushings are commonly used in mechanical engineering applications where components have experienced wear over time. Instead of replacing the entire shaft or housing, which can be a more expensive and time-consuming process, an oversize bearing bush can be installed. The larger internal diameter of the Übermaßlaufbuchse accommodates the worn surface of the shaft, effectively restoring the proper fit and function of the assembly.

The manufacturing process for an Übermaßlaufbuchse involves precision machining to ensure that the increased dimensions are accurate and that the bush maintains the correct tolerances for its intended application. They are often made from materials like bronze, brass, or various polymers, chosen for their wear resistance and lubricating properties. The use of an Übermaßlaufbuchse is a common repair and maintenance strategy in many industries, including automotive, industrial machinery, and agricultural equipment, to extend the service life of worn parts.
