Retaining rings

Design and operation of snap rings

They prevent axial displacement of structural elements and ensure their stable position during operation. The basic principle is its elastic grip on the part, which creates a secure fit. As a result, they are widely used in mechanical engineering, the automotive industry, aircraft construction, and other areas where precision and durability of connections are required. These fasteners can be internal or external, depending on how they are installed: internal rings are mounted in holes, while external rings cover shafts, providing a strong hold.

Snap ring sizes

The dimensions of circlips vary depending on the application and the standards to which they are manufactured. The main characteristics are the diameter of the bore or shaft, the thickness and the shape. It is important to choose the right size of the circlip so that it provides a secure hold without deformation or excessive stress on the part. Industrial and technical specifications usually use standard sizes that meet the requirements of international standards.

Range of circlips

The range of snap rings includes many variants that differ in design and application. Among the most common are models according to DIN 472, DIN 6799, DIN 7993-A, DIN 7993-B standards. DIN 472 and DIN 6799 are most often used for external and internal fastenings on shafts and in holes. At the same time, DIN 7993-A and DIN 7993-B are more specialized versions that are used in complex mechanisms operating under high loads.

How to choose the right retaining rings

To select the correct retaining rings, you must first determine whether they are internal or external. Then the diameter of the seating area must be measured: for inner rings - inner diameter, for outer rings - outer diameter. It is important to choose the right material depending on the operating conditions, e.g. steel, stainless steel or spring steel. It is also important to make sure that the ring complies with the required standard, such as DIN, GOST or ISO.

Where circlips are used

These fasteners are used in various industries that require reliable fastening of moving or static parts. In the automotive industry, they fix axles, bearings, and gears. In mechanical engineering, such rings are used to hold elements of mechanisms operating under load and vibration. In hydraulic and pneumatic systems, they are used to seal and protect components from axial displacement. They also find their application in household appliances, electrical equipment and many other areas where precise and secure connections are required.
