Helical Compression

Round and Rectangular Wire

Push - wide load and deflection range - constant rate.

Push - wide load and deflection range.

Conical springs can be made with minimum solid height and with constant or increasing rate.

Barrel, hourglass, and variable pitch springs used to minimize resonant surging and vibration.

Column 1:

1)Belleville
2)Wave
3)Slotted

Column 2:

4)Finger
5)Curved

1) Push - high loads, low deflections - choice of rates (constant, increasing or decreasing)

2) Push - Light Loads, low deflection-uses limited radial space.

3) Push - Higher deflections than bellevilles.

4) Push - for axial loading of bearings.

5) Push - uesd to absorb axial end play.
