The fish eye washer is an extraordinary fastener accessory with a distinctive concave-convex architecture. Here, we delve into a comprehensive portrayal of its structural attributes, versatile applications, material specifications, and the invaluable benefits it offers.
1, Structure and Material Characteristics
Revolutionary Concave-Convex Biomimetic Design
Advanced Pressure Dispersion Principle: Utilizing a fisheye-shaped convex surface, the washer disperses concentrated pressure across multiple convex points through point contact rather than surface contact. This innovation significantly mitigates local stress, thereby enhancing the stability and reliability of fastenings.
Core Material Excellence:
Stainless Steel 304 (A2-70): Renowned for its formidable corrosion resistance, this material is ideal for humid or outdoor environments, including shipbuilding, chemical equipment, and more.
Galvanizing Treatment: Select models undergo surface galvanization to amplify rust resistance and lengthen service life, perfect for high-load applications in mechanical manufacturing and construction engineering.
Specification
Extensive Standard Coverage: Available in common specifications such as M3-M12 (metric) and 4 # -18 # (imperial), these washers are designed to complement countersunk and semi-countersunk screws.
Bespoke Customization Service: Tailored non-standard customization is available to meet specific thread or size requirements according to customer needs.
2, Function and Application Scenarios
Augmented Tightening and Strengthening
Ingenious Anti-Loosening Design: The unique concave-convex structure increases friction and diminishes the likelihood of screws loosening due to vibrations or impacts, making it indispensable in precision sectors like mechanical equipment and electronic instruments.
Enhanced Sealing Assistance: Certain models, like the O-section, paired with sealing rings, provide superior shaft or hole sealing. This is ideal for cylinders, valves, and fittings that demand leak prevention.
Versatile Scene Adaptation
Industrial Manufacturing Prowess: In automotive parts, food machinery, and pharmaceutical equipment, fisheye washers ensure enduring operation due to their wear and corrosion resistance.
In civilian applications, such as furniture assembly and home appliance maintenance, these washers reduce material deformation risks and extend service life by effectively dispersing pressure.
3, Technical Parameters and Advantages
Wide Temperature Resistance Range: -40 ºC to 200 ºC / -20 ºC to 150 ºC. Exhibiting remarkable adaptability to extreme environments.
Longevity and Cost Efficiency: Service life extends beyond 5 years under normal conditions, while reducing maintenance costs by 60%.
4, Industry Application Cases
Automobile Making
Sliding Tower Top Modification: By integrating fisheye washers (wave top) into the suspension system, tire adhesion in corners is enhanced, leading to a 10% -15% increase in vehicle cornering speed.
Mechanical Engineering
Hydraulic Cylinder Sealing: Employing fisheye gaskets (like copper straw caps) at high-pressure oil pipe joints effectively prevents oil leakage, ensuring stable system pressure.
Construction Work
Steel Structure Connection: Incorporate fisheye washers at bolt fastening points to disperse stress concentration, thereby reducing the risk of connection failure due to material fatigue.
5, Selection and Usage Suggestions
Key Points for Informed Purchase
Strategic Material Matching: Select materials based on the environment of use. Stainless steel 304 is recommended for humid conditions, while SUS316 is ideal for highly corrosive settings.
Specification Confirmation: Ensure the thread size and screw model match, so that the washer's inner diameter aligns perfectly with the bolt's outer diameter, avoiding improper fitting.
Precautions for Use
Installation specifications: For optimal performance, ensure a precise and balanced installation of gaskets. This careful setup helps distribute force uniformly across the protrusions, effectively preventing any deformation that may arise from localized, excessive pressure.
Regular inspection: To maintain peak functionality, especially in environments subject to intense vibrations or elevated temperatures, it is crucial to conduct a thorough inspection of the gasket every 6 months. Swiftly replace any worn components to ensure sustained and reliable performance.
