    custom barrel springs by katy spring

    Types of extension springs

    Key Characteristics

    • Shape and Design: Extension springs are tightly coiled and usually have hooks, loops, or end coils at both ends. These ends attach to different components, providing a mechanism to exert force when the spring is pulled apart.

    • Material: These springs are typically made from high-tensile materials like stainless steel, music wire, or other durable alloys. This ensures they can withstand repeated stretching and return to their original shape without significant wear or deformation.

    • Load and Deflection: Extension springs are characterized by their load (the force required to extend the spring) and deflection (the distance the spring can be stretched). The spring’s design determines its load capacity and deflection range.

    Advantages of Using Extension Springs

    • Energy Storage: Extension springs efficiently store mechanical energy when extended, releasing it to return to their original position. This makes them ideal for applications requiring tension and recoil.

    • Durability: Made from robust materials, extension springs are resistant to fatigue, wear, and environmental factors, ensuring a long service life even under repeated use.

    • Versatility: With various sizes, materials, and end configurations available, extension springs can be tailored to fit a wide range of applications, from small precision devices to large industrial machinery.

    Best Practices for Custom Spring Orders

    • The normal squareness tolerance for ground ends is 2-3 degrees.|
    • Use conical compression springs when a short, solid height is needed to reduce buckling and surging.
    • Leave the wind direction optional for compression springs. Use right-hand wound when the compression spring is being threaded on a bolt, or one right and one left when two springs are being used inside the other to avoid meshing coils.
    • Make Katy Spring aware of the spring travel and any solid height requirements
    • Specify a force with a tolerance (+/- 10 percent) at an exact compressed height rather than a definite deflection. Spring rate is the difference of two forces divided by the amount of deflection between those forces.
    • Make Katy Spring aware of unusual conditions such as temperature, corrosive environments, impact force, and fatigue life.
    • Specify the mandatory requirements only to Katy Spring, and leave the exact wire size and number of coils to the discretion of Katy Spring whenever possible.
