Compression Springs FAQs

1. Can it deflect past L1?
Yes. However, it must be realized that the spring may set slightly.

2. Can the spring buckle?
As a rule of thumb, buckling can happen when the free length (L) is = 4 times the O.D.

3. Has the set been removed?
Set has not been removed from our stock springs. Deflecting a spring past L1 will cause it to take set. Set can be removed by compressing the spring to solid height. Most of the set will be removed after one compression. Excessive loads at solid height sho

4. Is the spring magnetic?
Type 302 stainless steel is slightly magnetic.

5. What about the grind?
All springs with exception of the C0057 and C0088 series are ground on both ends. The grind is a minimum of 270°.

6. What is the finish?
The finish is that of the plain wire. Music wire is oiled to prevent corrosion.

7. What is the Helix?
All compression springs are right-hand wound.

8. What is the linearity?
Compression springs are linear between 15% and 85% of the spring's available travel. Available travel can be computed by subtracting the free length from the solid height.

9. What is the number of coils?
It is always a reference dimension.

10. What is the squareness?
Squareness is within 3° for the springs in the free position.
