A retaining ring, also known as a retaining spring, is a part used for axial limiting. A flattened wire retaining ring is one of the types made of flattened wire. It can prevent other parts from axial movement and ensure the stability and reliability of the mechanical device. According to the usage scenario and installation location, the flattened wire retaining ring can be divided into a hole retaining ring, a shaft retaining ring and a C-type retaining ring. Hole retaining ring: mainly used to be installed in the hole, and its elasticity or rigidity is used to limit the axial movement of the shaft or other parts. Shaft retaining ring: mainly used to be installed on the shaft, and its structural characteristics are used to fix the parts on the shaft to prevent axial movement. C-type retaining ring: mainly used to be installed on the shaft. Due to the influence of its use environment, the shaft flattened wire retaining ring cannot be used for assembly (i.e., installed into the groove from one end of the shaft), and radial installation is required. In addition, affected by the usage scenario and installation location, some retaining rings have added mounting holes or slot designs to cooperate with calipers for installation operations.

Automotive stamping parts play an important role in the automobile manufacturing process. They not only provide structural and functional support for vehicles, but also become an indispensable component due to their efficient production and low cost.

A retaining ring, or snap ring, axially limits components. An elastic retaining ring, made by sheet - metal punching, has a radially - gradually - deforming width (from wide to narrow) and an attached ear with a mounting hole at the opening. It ensures mechanical device stability by preventing axial movement of other parts. Based on usage scenarios and installation locations, it can be classified as follows: Hole - type elastic retaining rings: Installed in holes, they restrict the axial movement of shafts or other parts via their elasticity or rigidity. Shaft - type elastic retaining rings: Installed on shafts, they prevent axial movement by fixing components on the shaft using their structural features. E - type open retaining rings: Installed on shafts, due to the use environment, they can't be installed like shaft - type elastic retaining rings (from one end of the shaft into the groove) and require radial installation.

A shim is a thin piece of material used to adjust the gap or position between mechanical parts. It is usually made of metal, plastic or other suitable materials with precise thickness and size to ensure that the mechanical device can operate as designed.

Wave spring, also known as wave spring, is an elastic element with several peaks and valleys on a thin metal ring. It is a high-end elastic element, a thin plate annular elastic metal unit composed of multiple peaks and valleys.

The ball pin is an important part of the car's steering tie rod connection, mainly used for the articulation of the steering mechanism, such as the articulation of the car's steering mechanism and suspension. It enables the up and down bouncing and steering movement of the wheel, ensuring the flexibility and stability of the car's driving.

A spring is a mechanical part that uses elasticity to work. It is made of elastic material and will deform under the action of external force and return to its original shape after the external force is removed.

Special-shaped circlips, as the name suggests, refer to circlips that are different in shape, size or function from traditional standard circlips. Such circlips usually have irregular contours and complex angle designs to meet the needs of specific application scenarios. Their characteristics include high customization, good elasticity and reliable fixing effect.
