FAQ Spring

Question: What are the different types of springs?: Answer: There are many types of springs, but some of the most common include:
Compression springs: These coils compress when force is applied. They are used in everything from pens to car suspensions.
Extension springs: These coils stretch when force is applied. They are often used to counterbalance weight or create tension.
Torsion springs: These coils twist when force is applied. They are used in hinges and clamps.
Die springs: These compact springs offer high force in a small space.
Question: What information do I need to find the right spring?: Answer: In order to choose the right spring, you will need to know the following:
The type of spring you need (compression, extension, torsion, etc.)
The dimensions of the spring (wire diameter, coil diameter, free length, etc.)
The spring rate
The material
Question: Are materials of round wire coil spring (SWP-A and SUS304-WPB) magnetic material?: Answer: Both of them are magnetic material.
Question: At which spring deflection position does the maximum load (N max)?: Answer: Load at maximum deflection of spring (F max)
Spring may be damaged if it travels over the deflection limit.
Question: What is Total number of winding and number of active windings of tension spring?: Answer: Total number of windings ={L-2 (D-d) }÷d
Number of active windings＝ Total number of winding -2
Total number of windings is only for reference value, it varies to production lot of spring.
Question: What is total number of winding and number of active windings of round wire coil spring?: Answer: Total number of windings＝solid length÷wire diameter (d) -1
Number of active windings＝ Total number of winding -2
Total number of windings is only for reference value, it varies to production lot of spring.
Question: How do you calculate the force required to compress a spring?: Answer: Force required to compress a spring＝
Pre-tension (N) + Spring constant (N/mm) ｘSpring deflection (mm)
