Features：

Retaining ring (or snap ring) features one or more integral tabs or protrusions designed to engage with a notch or keyway on a shaft or housing. These tabs help prevent rotation and movement of the ring, providing additional stability and security in high-vibration or high-load applications.

Based on the installation position, it can be categorized into shaft and hole types:
For shaft applications: The retaining ring is installed on the designated shaft. Depending on the installation method, it can be classified as fastening (axial installation) or bearing support (radial installation).
For bore applications: The retaining ring is installed on the designated bore and groove.

Spiral Retaining Ring：

Spiral Retaining Ring is a type of earless retaining ring that consists of a coiled, flat metal strip wound into multiple turns to fit into a groove on a shaft or inside a bore. Unlike traditional snap rings, it has no ears (lugs or protrusions), making it ideal for applications where a smooth and uninterrupted circular profile is required.
