Compression Springs FAQ


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.

What is the Helix?

All compression springs are right-hand wound.

Can the spring buckle?

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

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 ho.

Is the spring magnetic?

Type 302 stainless steel is slightly magnetic.

What is the finish?

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

Can it deflect past L1?

Yes. However, it must be realized that the spring may set slightly.

What is the number of coils?

It is always a reference dimension.

What about the grind?

All Compression springs ground on both ends.


Tension Spring or Extension Springs FAQ

 

Number of coils

It is always a reference dimension.

Helix?

Extension springs are left- or right-hand wound.

What are the hooks?

All extension springs have full hooks which have not been cut for installation purposes. Closed loops are provided to help alleviate tangling. The I.D. of the hook is approximately equal to the I.D. of the spring body.

What about the end positions?

Springs are manufactured with end positions.

What is the finish?

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

Is the spring magnetic?

Type 302 stainless steel is slightly magnetic.

Can it be deflected past L1?

No. L1 is the recommended maximum deflection for static applications.

Torsion Springs FAQ

 

What is torsion springs?

A torsion spring is a spring that works by torsion or twisting; that is, a flexible elastic object that stores mechanical energy when it is twisted. When it is twisted, it exerts a force (actually torque) in the opposite direction, proportional to the amount (angle) it is twisted.

How many types of torsion springs are there?

There are two types of torsion springs are there, Torsion bar (Torsion fiber) & helical torsion spring (Small coil torsion springs)

What is the application of torsion springs?

 

What is the application of torsion springs?

To operate clothespins & Mouse Strap

Small coiled torsion springs for POP doors on small consumer goods like digital cameras and compact disc players

Vehicle

Which are synonyms of torsion springs ?

Small coiled torsion springs, Helix coil spring, helical torsion spring, coil spring, torsion spring

Wave Spring Washers FAQ

 

Can it deflect past H1?

Yes. It should be noted that loads are greater than computed when a washer is deflected more than 80% of its available travel. It must be understood that the spring may set, however.

What is the linearity?

Wave washers are linear between 20 and 80% of the spring's available travel. Available travel can be computed by subtracting the thickness "t" from the height "H".

What kind of plating?

Electroplating is permitted although Hydrogen cracking is still possible. Mechanical plating can be used as an alternative because it substantially reduces this risk. The washers can also be black-oxided, or phosphate-coated.

What are the advantages of Series stacking?

Series stacking increases the amount of available travel. The load-carrying ability of the stack does not increase. In a theoretical world, the applied load is equally transmitted to each washer. To stack properly, spacers must be inserted between washers.

What are the advantages of parallel stacking?

Although Parallel stacking increases the load proportionally to the number of washers, it is not recommended, due to the manner in which wave washers orientate in parallel.

Is the spring magnetic?

Type 302 stainless steel is slightly magnetic.

What is the finish?

It is that of the plain material. Carbon steel is oiled to prevent corrosion.
