What is the initial tension?

It can be understood that when a general tensile spring is under tension, the tension measured when it is about to undergo elastic deformation without deformation (critical state) is called the initial tension. It is realized by properly controlling the process parameters in the manufacturing process of tensile spring. MISUMI tension spring specifications (except for free designation) have been standardized, i.e. the maximum load of the same diameter is a certain value. Because the tensile spring is made on the basis of the maximum load, the initial tension and spring coefficient are the reference values.

What is the life of the tensile spring?

Some hook installation methods of tension springs may cause stress concentration, so the standard use times cannot be provided. To increase the use times, it is recommended to use it under 70% of the allowable displacement Fmax. · It is recommended to use it at room temperature below 40°C, and the load value will decrease due to service conditions at temperatures over 40°C .

What is the spring constant?

The spring constant is the force necessary to give the spring unit displacement, which is used to express the characteristics of the spring.

What are the JIS standards for general spring-related materials?

Piano wires: JIS G 3522 Iron wires: JIS G 3532 Hard drawn steel wires: JIS G 3521 Stainless steel wires for springs: JIS G 4313

What is the difference between a piano steel wire spring and a hard drawn steel wire spring?

There is little difference in appearance between the two materials. In short, the piano wire is an advanced material, and the hard drawn steel wire is a general material. The piano wire is often used as a spring for precision machinery while the hard drawn steel wire is mostly used as a peripheral spring for groceries or blinds. They are both high-carbon steels with almost the same chemical composition. The production of piano wires is time-consuming and they are expensive because there is additional standardized management and inspection of impurities, the depth of surface scars, and the depth of decarburized layer. Although the subtle difference is invisible to the naked eye, it has a great influence on the quality of the spring.

Specification Overview

The initial tension and the spring constant are reference values, which are different slightly depending on batches. Load {kgf} = Load N × 0.101972
Method for calculating the number of coils (reference value):
Total number of coils = (L - 2 (D - d)) / d
Effective number of coils = Total number of coils - 2
The number of coils is a reference value and may vary slightly depending on the batch.

Product Features

Tension spring (also known as draw spring) is a spiral spring which bears axial tension. It has side hooks at both ends to ensure the tension source of tension spring.
When not bearing load, the coils of tension spring are generally tight without clearance.
The working principle of tension spring is to act in reverse when stretching or pulling away, and to work by using the resilience (pulling force) after stretching, so as to control the movement of machine parts, absorb and store energy, measure the force and so on.

■ Corrosion resistance: 72-hour salt spray test

· Conclusion: Rust resistance is 9 times that of market products
· Differences between economy extension springs, standard products, and market-available products

· Product information: Material: SUS304-WPB

· Test conditions: Initial length 40 mm, allowable displacement 19.2 mm, allowable load 24.52N, stretching frequency 309 times/minute

· Conclusion: Service life is 3.08 times that of market products
*Products circulating on the market are similar products randomly purchased by our company from online or offline markets
* The test data are obtained through testing by our company, which are for reference only

Precautions

[Precautions for Use]
▶Operating temperature
SWP-A type: Room temperature (0–40°C)
Stainless steel type: -10–100°C
*If used under conditions exceeding the above temperature, the load value may decrease depending on the usage conditions.
When used in an environment with high and low temperature differences and humidity such as outdoors, it is recommended to choose stainless steel products.

▶Approximate usage standard: around 1,000,000 times
*The above number of times is for reference only. The number of times of use varies with the tensile direction, operating temperature/environment, and amount of deformation. To increase the usage count, it is recommended to use the spring up to 70% of the allowable displacement Fmax..

▶Others
· Use within the allowable displacement Fmax. (mm). If it is used under the condition of exceeding the allowable displacement, the spring may be deformed, or damaged after using only a limited number of times. Please also be careful not to stretch the tensile spring beyond the allowable displacement when installing it.
· Stainless steel springs are also magnetic. Please be careful.

Frequently asked question (FAQ)FAQ

Question:Question: What is the initial tension?: Answer:Answer: It can be understood that when a general tensile spring is under tension, the tension measured when it is about to undergo elastic deformation without deformation (critical state) is called the initial tension. It is realized by properly controlling the process parameters in the manufacturing process of tensile spring.
MISUMI tension spring specifications (except for free designation) have been standardized, i.e. the maximum load of the same diameter is a certain value. Because the tensile spring is made on the basis of the maximum load, the initial tension and spring coefficient are the reference values.
Question:Question: What is the life of the tensile spring?: Answer:Answer: Some hook installation methods of tension springs may cause stress concentration, so the standard use times cannot be provided. To increase the use times, it is recommended to use it under 70% of the allowable displacement Fmax.
· It is recommended to use it at room temperature below 40°C, and the load value will decrease due to service conditions at temperatures over 40°C .
Question:Question: What is the spring constant?: Answer:Answer: The spring constant is the force necessary to give the spring unit displacement, which is used to express the characteristics of the spring.
Question:Question: What are the JIS standards for general spring-related materials?: Answer:Answer: Piano wires: JIS G 3522
Iron wires: JIS G 3532
Hard drawn steel wires: JIS G 3521
Stainless steel wires for springs: JIS G 4313
Question:Question: What is the difference between a piano steel wire spring and a hard drawn steel wire spring?: Answer:Answer: There is little difference in appearance between the two materials. In short, the piano wire is an advanced material, and the hard drawn steel wire is a general material.
The piano wire is often used as a spring for precision machinery while the hard drawn steel wire is mostly used as a peripheral spring for groceries or blinds.
They are both high-carbon steels with almost the same chemical composition. The production of piano wires is time-consuming and they are expensive because there is additional standardized management and inspection of impurities, the depth of surface scars, and the depth of decarburized layer.
Although the subtle difference is invisible to the naked eye, it has a great influence on the quality of the spring.
