DIN 137A / GB 860 Curved Spring Washer
Curved spring washers are specialized elastic components designed to provide axial tension and accommodate thermal expansion, vibrations, or dimensional variations in assemblies. Their curved design allows for smooth and reliable force distribution, making them ideal for precision applications.




Features and Performance:
• Material Options:
• Carbon Steel (65Mn, C75S): Ensures excellent elasticity, wear resistance, and long-lasting performance under repetitive stress.
• Stainless Steel (AISI 304, 316): Offers outstanding corrosion resistance for use in demanding environments.
• Specialty Alloys: Available for high-temperature or unique performance requirements.
• Surface Treatment:
• Black oxide coating for improved wear resistance and reduced friction.
• Zinc plating, nickel plating, or passivation for enhanced corrosion protection.
• Performance:
• Provides consistent and predictable axial force.
• Absorbs vibrations and compensates for assembly tolerances, reducing the risk of loosening.
Applications:
• Frequently used in mechanical assemblies, automotive systems, and industrial machinery to maintain tension in bolted connections or bearing assemblies.
• Suitable for use in precision instruments, electronics, and dynamic systems where consistent force is required.
Advantages:
• Smooth load-bearing characteristics and low stress concentration.
• Easy to install, with compact design suitable for space-limited applications.
• Custom dimensions and materials available to meet specific requirements.
