The DIN 984 standard describes elastic retaining rings for holes of type A, also known as hole circlips or hole retaining rings. These retaining rings are designed to be installed in holes and by their elastic action to fix or locate parts on the shaft against axial movement.

Carbon Steel: Typically used for general applications.

Stainless Steel: For environments where corrosion resistance is required.

Alloy Steels: Used in applications requiring high strength or high temperature resistance.

Advantage:

Elastic locking: The elastic retaining ring for A-type holes utilizes its elastic deformation to provide locking force, effectively preventing axial movement of parts in the hole. Easy installation: Retaining rings are easy to install and remove without special tools for quick maintenance and replacement. Corrosion resistance: the material is usually spring steel, the surface may be galvanized or other surface treatment to improve corrosion resistance. Various materials: Different materials can be selected according to different application requirements, such as carbon steel, stainless steel, alloy steel, etc., to adapt to different working environments.

Scope of Application

Mechanical Manufacturing: In the field of mechanical manufacturing, it is used to fix rotating or sliding parts such as gears, bearings and bushings. Automotive industry: in the engine, gearbox, chassis and other key parts of automobiles to ensure the correct positioning and fixation of parts. Electrical equipment: In electrical equipment, used to keep electrical connectors and terminals in place and prevent loosening due to vibration. Aerospace: In aerospace, to ensure the precise installation and fixing of critical components to withstand extreme operating conditions.
