Springs

Conical / Taper Spring

Cone-shaped compression springs that telescopically compress into their own height.

Engineered cone-shaped compression springs where the coil diameter gradually decreases from base to top. Allows the coils to telescope inside each other when compressed, achieving a solid height equal to a single wire diameter.

Specifications

Technical profile

Geometry
Conical tapered profile (constant or variable pitch coiling)
Solid height
Telescopic nesting allows ultra-low solid height (approx. 1× to 2× wire dia)
Spring rate
Non-linear progressive spring rate (stiffens as larger coils bottom out)
Material grades
SS304 / SS316 / Music Wire / Phosphor Bronze / 17-7 PH Stainless
Stability
Natural lateral stability prevents buckling even at high slenderness ratios
Wire diameter
0.4 mm to 8.0 mm wire stock

Key benefits

Why this product

  • Telescopic coil nesting saves up to 70% axial space in low-profile battery contacts and push-button valves
  • Progressive spring rate provides soft initial cushioning followed by high resistance against overload bottoming
  • Broad base diameter provides inherent self-centering stability without requiring internal guide rods
  • Natural resonance damping prevents spring surging in high-speed reciprocating valve mechanisms
