E-Type Snap Ring (E-Clip) - Stainless Steel/Carbon Steel
The E-type retaining ring (snap ring) is a mechanical component used on shaft ends to prevent axial movement of parts. It conforms to the GB896 standard, is made of stainless steel or carbon steel, and is available in a wide range of specifications.
Why Choose the E-Type Snap Ring?
Space Saving: With a thickness typically less than 1mm, it saves up to 90% space compared to traditional nuts.
Anti-Rotation: Its three-point contact design effectively prevents parts from shifting.
Shock Absorption: The elastic material absorbs minor vibrations.
Corrosion Resistance: Commonly made from stainless steel, it withstands humid environments
The Cardinal Rule for Selection
When measuring the installation location, remember the 'Three-Measurement Rule':
Inner Diameter determines the snap ring size.
Outer Diameter affects the fixing range.
Thickness correlates with the load capacity.
A common mistake is focusing solely on the inner diameter while neglecting the other parameters. In reality, these three dimensions are like the three legs of a stool – none can be omitted

Key Applications:
Automotive Industry: During automotive manufacturing, E-type snap rings are frequently used for connecting and securing core components such as engines, gearboxes, and steering systems. For example, in the connection between the engine crankshaft and the connecting rod, E-type snap rings effectively ensure the axial positioning of the crankshaft and connecting rod, thereby preventing loosening or disengagement caused by vibration or impact.
Aerospace Sector: The aerospace sector imposes stringent requirements on connection stability and precision. E-type snap rings, with their distinctive shape and stable performance, serve as critical fasteners for connecting and securing core components like aircraft engines and landing gear.
Machinery Manufacturing: In the machinery manufacturing process, E-type snap rings are commonly employed for connecting and securing components like transmission shafts and bearing housings. By carefully selecting the appropriate size and tolerance specifications, E-type snap rings effectively ensure the axial positioning of the transmission shaft and bearing housing, thereby enhancing the stability and reliability of the mechanical system.
Electronics Manufacturing: Electronics manufacturing demands extremely high levels of precision and reliability, making the selection and use of E-type snap rings particularly crucial. In the fixing and positioning of components like circuit boards and connectors, E-type snap rings play a vital role in ensuring the stable operation of electronic devices.
