3E-4371 Internal Retaining Ring
Cat® 229.49 mm Free Diameter Internal Snap Ring
Description
An internal retaining ring, also known as an internal snap ring or circlip, is a fastener used to secure and fasten components inside a bore or housing. Unlike external snap rings that are installed on a shaft or pin, internal snap rings are installed inside a bore or groove to hold components in place. The main purpose of an internal snap ring is to prevent axial movement or displacement of components inside the bore or housing. It acts as a retaining device that holds components such as bearings, shafts or seals securely in place.
Features
- Manufactured to exact specifications for rugged durability, reliable performance and high efficiency.
- Made of durable materials for high strength and corrosion resistance.
- Compressed snap ring inserts into the groove or recess of the bore.
Applications
The internal retaining ring is used to secure the bearing in the bearing cage and keep it in place in the transmission planetary.
