Crest-to-Crest® Wave Springs (Metric)

Crest to Crest Springs are pre-stacked in series, decreasing the spring rate proportionally to the number of turns. Uses are typically applications requiring low-medium spring rates and large deflections with low-medium forces.

Product Information

Crest to Crest Springs are pre-stacked in series, decreasing the spring rate proportionally to the number of turns. Uses are typically applications requiring low-medium spring rates and large deflections with low-medium forces.

As a replacement for helical compression springs, our Crest to Crest spring can develop similar forces, yet occupy 50% or less axial space. This allows for strict space constraints and reduced operating heights, free heights, and solid heights.

Our Crest to Crest Spring are also available with squared-shim ends. Shim ends provide a 360° contact surface when compared to the wave point contact of plain ends.

Dimensions: millimetres (mm)
* Not available with shim ends
Use part number prefix “YCM” for plain ends. Use YCMS prefix for squared-shim ends.
Add suffix -S17 for 17-7 stainless steel.
