Descripton of special shaped spring:

hourglass-shaped compression springs allow for "telescoping" - a term which describes when coils are formed in order to allow some of them to go "inside" other coils when the spring is compressed.


hourglass-shaped compression springs offer the advantage of a reduced solid height compared to straight compression springs, especially when capable of "telescoping." Conical Compression Springs are cone shaped springs designed to provide a near constant spring rate and a solid height lower than a normal spring. Each spring features a variable pitch to achieve the constant spring rate and coils which nest during deflection to provide a solid height approximately equal to two wire diameters.


Some uses for conical shaped springs are as follows:

  • Small Solid Height: A Conical spring can be designed so that each active coil fits within the next coil, so the solid height can be equal to one or two thickness of wire. This is useful where the solid height is limited.
  • Variable Rate: These springs offer a constant, or uniform pitch, and have an increasing force rate instead of a constant force rate (regular compression springs). The larger coils gradually begin to bottom as a force is applied. A variable pitch can be designed to give a uniform rate if necessary.
  • Stability: Conical compression offers more lateral stability and less tendency to buckle than regular compression springs.
  • Vibration: Resonance and vibration is reduced because Conical Compression springs have a uniform pitch and an increasing natural period of vibration (instead of a constant) as each coil bottoms.
