Accordion Springs

Accordion springs are flat, accordion-shaped compression springs engineered to deliver high torque damping in a compact form factor. They smooth out power transfer and absorb torsional vibrations, protecting critical components in places where traditional coil springs cannot perform effectively. Thanks to their lightweight, folded design, accordion springs provide stable repetable stiffness under demanding conditions. We use them to replace traditional helical springs when axial space, mass, or dynamic response are critical constraints.

RPK Group manufactures custom accordion springs tailored to your performance requirements, defined by material thickness, number of folds, pitch, radii, and free length. We validate every design through FEA and manufacture high-volume parts using high-speed multislide technology, ensuring repeatable stiffness, durability, and tight tolerances. We select high-grade spring steels to guarantee consistent performance under high-cycle, high-torque conditions. The result is a robust spring that maintains its damping characteristics over a long service life without set or load loss.
