The DIN 984 standard describes retaining rings with holes, which are also commonly referred to as elastic retaining rings for holes. These retaining rings are designed to be mounted in holes and, by their elastic properties, to fix or lock parts of the shaft against axial or radial 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:

SELF-LOCKING FUNCTION: The perforated retaining ring has a self-locking function that provides a strong hold on the part without an additional locking device. Ease of operation: The installation and removal process is simple and does not require complicated tools, allowing for quick maintenance and replacement. Material Versatility: These retaining rings can be made from a variety of materials, including various grades of carbon steel, stainless steel, and alloy steel to suit different applications. Corrosion and Wear Resistance: The corrosion and wear resistance of the retaining ring is enhanced by galvanizing, nickel plating or other surface treatment techniques.

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.
