Wire retaining ring for hole DIN 7993B 7 mm

Product detailed description

The DIN 7993B wire-wound retaining ring with a diameter of 7 mm is specifically designed for applications requiring light axial locking inside the hole. This component is ideal for less demanding applications where mounting space is limited. It is made of spring steel, which provides the necessary flexibility and resistance, but without additional surface treatment, which is important to consider in applications exposed to corrosive environments.

The geometric parameters of this ring include a diameter of d 7 mm, which is the basic dimension for the hole in which the ring is installed. The diameter d1 is 7.8 mm and the diameter d2 is 7.9 mm, which provides a slight expansion for a secure fit in the hole. The wire diameter, designated as d3, is 0.8 mm, which ensures sufficient strength while maintaining flexibility. The radius r is 0.5 mm, which contributes to the optimal distribution of stress in the material under load. The width of the e-ring is 4 mm, which is important for proper seating and function in the application.

The DIN 7993B standard and the equivalent ČSN 022925 standard define precise design and material requirements for this type of circlip, ensuring its reliability and consistency in industrial applications. This wire ring is suitable for use in various mechanical assemblies where components need to be secured against axial displacement within a hole.
