Conical spring

Conical spring resist compressive forces and store mechanical energy when compressed. Once theload is released, they return to their original shape. They can be produced in a wide range of wire diameters,lengths, and load requirements. Materials include stainless steel, carbon steel, and alloy steel. Surface treat-ments are available to enhance corrosion resistance and durability.

Applications:

automotive suspension and braking systems, engine components, mechanical valves, shock absorbers, household appliances, industrial machinery, agricultural equipment, medical devices, and precision instruments.

All dimensions are in mm

  • Dt = Wire diameter
  • Dm = Mean diameter
  • Di min = Inner diameter with smallest possible tolerance
  • Lo = Unloaded length
  • nt = Total number of coils
  • Ln = Permitted loaded length for static load
  • Fn =Spring force in Newtons at Ln
  • R = Rate Newton / mm
  • Po = Pitch
  • Lst = Solid length = Dt x nt
  • s = Deflection

Conical spring for general use.Dimensions according to international standards.

Min load length and temperature

Springs having a calculated high stress under load to Ln are pre-set to solid length.

Pre-setting

Minimum load length Ln applies for static or pseudo static loaded springs operating at temperature up to about 40℃ for unalloyed springs and up to about 150℃ for stainless steel springs.

The relaxation, i.e. the power loss over time, will then stay within acceptable values for most applications. At higher operating temperatures or dynamic life demands, more than 10,000 cycles, the spring should not be loaded as far as Ln·

Inspection& Shipment

All springs are fully inspected for dimensional accuracy, mechanical performance, and surface quality before being stored. Only approved products are released to the warehouse and prepared for shipment following final order verification and packaging.
