Characteristics:

To accommodate different axle diameters and the sizes of parts that need to be fixed, this retaining ring is available in a variety of standard sizes for selection.
The retaining ring is constructed from a circular metal disc with an opening in the center, featuring a simple structure that facilitates easy installation.
The retaining ring can be effortlessly installed onto the axle with axial pushing and tapping, eliminating the need for any special tools or equipment.
Due to the varying working environments and requirements of retaining rings, they are constructed from a range of materials, including stainless steel, carbon steel, copper alloys, and more.

Advantages:

Retaining rings guarantee the stability and reliability of mechanical systems by effectively preventing the displacement or detachment of parts from the axle.
Due to their simple structure, retaining rings are suitable for large-scale production, resulting in relatively low manufacturing costs.
High Adaptability: Retaining rings can adapt to various axle diameters and part sizes, demonstrating strong versatility.
Easy Maintenance: Both installation and removal of retaining rings are relatively straightforward, facilitating equipment maintenance and part replacements.

Applicable Scenarios:

Transmission Parts on Axles: In transmission systems, such as gears and pulley wheels, retaining rings can be used to fix parts onto axles.
Bearing Fixation: In some applications, it is necessary to ensure the stability of bearings on axles, where retaining rings come into play.
Positioning Elements: Retaining rings can also serve as positioning elements, ensuring accurate relative positions of other parts on axles.
Frequent Part Replacement Scenarios: Due to their ease of installation and removal, retaining rings are particularly suitable for scenarios requiring frequent part replacements, such as in test equipment and testing benches.
