Description
The 304 Stainless Steel External Snap Ring is a crucial fastener designed for positive axial positioning of components on a shaft. Conforming to the Chinese National Standard GB894.1, this headless, semi-flexible lock washer is seated into a machined groove on a shaft, creating a secure shoulder that prevents parts (like bearings, pulleys, or gears) from moving along the shaft's axis. Constructed from premium 304 Stainless Steel, this external snap ring offers exceptional high wear resistance and robust corrosion resistance, making it ideal for machinery, automotive, and industrial applications exposed to moisture or environmental humidity. The standardized design, featuring standard clamp holes at the ends, allows for quick, tool-assisted installation and removal, greatly contributing to faster assembly and maintenance times.
Features & Benefits
- Superior Axial Retention: Provides a reliable mechanical stop, ensuring components remain precisely positioned on the shaft and preventing axial movement.
- High Corrosion & Wear Resistance: Made from premium 304 stainless steel, offering strong resistance to rust, oxidation, and humidity—ideal for indoor and outdoor environments.
- Standardized Design for Easy Assembly: Manufactured to GB894.1 specifications with precise clamp holes for quick installation using circlip pliers, reducing assembly time and slippage risk.
- Durable Construction: The robust thickness and high hardness prevent deformation, maintaining a continuous tightening seal and securing force.
