Meander spring V spring cantilever spring SS301

The V spring, also known as a cantilever spring & meander spring, is the most commonly used energizer in spring energized seals. With its V-shaped or U-shaped cross-section, the spring applies consistent force to the sealing lip, ensuring reliable sealing and wiping performance in dynamic and static applications.

  • Medium load with wide deflection range – provides excellent flexibility for diverse sealing applications.

  • Enhanced compensation capability – maintains effective sealing even under wear or material deformation.

  • Tolerance for shaft runout and eccentricity – ideal for conditions with shaft misalignment or radial movement.

  • Reliable wiping effect – ensures clean contact and prevents leakage of fluids, gases, or contaminants.
