Stützenring

A Stützenring, also known as a support ring or retaining ring, is a mechanical component used to maintain the position of a shaft or other cylindrical part within a housing or bore. It is typically made of a resilient material such as rubber, plastic, or metal, and is designed to provide a tight fit around the shaft while allowing for some axial movement.

Stützenringe are commonly used in various industries, including automotive, aerospace, and manufacturing, to prevent axial displacement of shafts and ensure proper alignment and function of mechanical assemblies. They can also help to reduce wear and tear on the shaft and housing by distributing the load more evenly.

There are different types of Stützenringe, including fixed rings, floating rings, and spring rings, each designed for specific applications and operating conditions. Fixed rings are secured in place and do not move axially, while floating rings can move axially within a certain range to accommodate thermal expansion or contraction of the shaft. Spring rings, on the other hand, use a spring mechanism to provide a constant force to maintain the shaft's position.

Proper selection and installation of Stützenringe are crucial for the reliable operation of mechanical systems. Factors such as the material properties, dimensions, and operating conditions must be carefully considered to ensure optimal performance and longevity of the Stützenring and the overall assembly.
