Cantilever V Spring

Cantilever V Spring Overview

Cantilever V Spring is also known as: Meander V Spring, V Spring, Elgiloy Cantilever Spring, Punch Finger Spring.

V-Spring is a cantilever beam geometry made from stainless steel or other alloys and is applied as a radial or axial compression energizer inside of U-Cup type seals. The V-Shape provides a moderate load over a wide deflection range and is used in dynamic and static applications. The V-spring is available in six standard sizes and can be ordered by the foot or cut and welded to specific diameters. Custom sizes and materials are also available.

What Makes Cantilever V Springs Unique?

A cantilever V spring is defined by its distinctive “V” shape and single-point mounting, combining the rigidity of a cantilever design with the flexibility of a coiled spring. This unique structure offers:

  • Controlled Deflection: The V-shaped profile ensures predictable, linear force distribution across a wide range of deflections, making it ideal for applications requiring precise load management. in infusion pumps, ventilators, and drug delivery systems

  • Space Efficiency:
    Compact design fits into tight assemblies where traditional springs can’t—critical for miniaturized devices and high-density machinery.

  • High Cycle Life: Manufactured from premium alloys, our springs withstand millions of cycles without fatigue, reducing maintenance and replacement costs.

  • Customizable Force: Tailored to your exact load requirements (from ounces to tons) through material selection, thickness, and V-angle adjustments.

    Standard Size Range & Materials

    The Cantilever V Spring chart below shows the standard dimensions of the Standard V Cantilever/Meander type springs. All dimensions are subject to standard manufacturing print tolerances. Those tolerances may be requested if needed. Each Cantilever V Spring is manufactured in its own standard tool & die set. If these dimensions do not work for your situation minor variations to “L “and “K” can be made with minor adjustments to our standard tooling.

    However if you are needing more aggressive changes such as width of the raw material or radius dimensions we suggest you inquire about one of our 100 or more other nonstandard cross sections of V and U springs.

    The table is a part of specification size, more specifications please see attached. You can also contact engineers for customization.
