Conical Springs
Conical springs are a type of compression spring with a wider diameter at the base and a smaller diameter at the top.
This design has the benefit of allowing a reduced solid height as the smaller coils will fit partially, or sometimes fully, inside the larger coils below.

Tension Spring End Types
The 5 commonly used end types are:
- Machine Loop
- Crossover Loop
- Side Loop
- Extended Ends
- Coned Ends

Common Mistakes in Torsion Spring Design & Use
There are 4 key Torsion Spring design flaws that can affect the performance of a torsion spring.
- Incorrect direction of operation
- Inside diameter too small
- Body length too large
- Overstressed

Torsion Spring Leg Types
Torsion spring legs come in many different forms, with almost infinite possible variations.
There are four main torsion spring leg types, determined by the way the legs leave the spring body
- Tangential
- Axial
- Radial
- Radial Over-Centre

Initial Tension
The initial tension is released, when a tension spring is extended to a certain point, where gaps appear between the coils.

Tension Spring Rate
The rate is the strength of a spring as defined by Hooke’s law.
Hooke’s Law states that the force needed to extend a spring is directly proportional to the distance you stretch it. Hooke’s Law can be represented as F = ks.
‘F’ is the spring’s restoring force
‘k’ is the spring constant
‘s’ is the deflection (extension)

Counting Coils on a Tension Spring
Counting coils on a tension spring is the same as counting coils on a compression spring.
The type of ends on a spring will make no difference to the number of coils.

Loads at Length for a Tension Spring
How spring loads work within a tension spring. If too much weight is applied to the spring it will no longer contract, therefore breaking the spring.

Outside Diameter Expansion of a Compression Spring
As a spring is compressed the pitch of the spring is reduces, expanding the outside diameter.

End Types of a Compression Spring
There are three different kinds of end types of a compression spring.

Active & Dead Coils of a Compression Spring
Compression springs can consist of active coils and dead (inactive) coils.
The active coils can take stress or loads. The dead (inactive) coils cannot support any load.

Spring Winding Direction
This video in our Springtelligence video series will show you the winding direction of a spring.
If two compression springs have to operate together (one inside the other) it is important for them to be wound in opposite directions, this will prevent the coils from getting entangled.

Gap & Pitch of a Compression Spring
This video in our Springtelligence video series will show you the gap between two adjacent coils of a compression spring and the simplest method of measuring the pitch on a compression spring.

Diameters of a Compression Spring
The third video in our new Springtelligence video series will show you the Wire Diameter (d), Outside Diameter (OD), Inside Diameter (ID), and Mean Diameter (D) of a compression spring.
Watch the video to find out how to identify and then measure the Wire Diameter (d), Outside Diameter (OD), Inside Diameter (ID), and Mean Diameter (D) of a compression spring.
Measuring Compression Spring Lengths
When specifying springs you must know your spring’s dimensions. There are millions of possibilities when it comes to spring design, so just knowing the working loads or the spring rate will not be enough as the spring can be any size in diameter or length.
Watch the video to find out how to measure compression spring lengths.
How To Count Coils
Counting the coils of a spring is one of the most frequently misinterpreted concepts of spring manufacturing. Failure to count and specify coils correctly can result in errors in specification drawings which can then carry through to the final production of the spring.
Watch the video to find out how to count coils correctly.
