Product Feature of Round Wire Springs

Different from ordinary springs on the market, MISUMI Round Wire Springs are more precise and refined, divided into the inner diameter standard type and the outer diameter standard type, the former of which is manufactured givingpriority to the inner diameter tolerance while the latter is manufactured giving priority to the outer diameter tolerance.

Select an appropriate Round Wire Springs type according to the actual installation situation, and refer to the published content for the specific inner and outer diameter tolerance values.
* The solid length is a reference value. If it is used under the limit condition of the solid length, the spring may be deformed, or damaged after using only a limited number of times. Therefore, use within the allowable displacementFmax.(mm).
To increase the usage count, it is recommended to use the spring up to 70% of the allowable displacement Fmax..

Example Use of Round Wire Springs

Example of Use for Springs
Hole Reference Positioning Mechanism
A Round Wire Springs is mechanism for positioning the workpiece based on the hole reference.
Loosening during positioning can be reduced by using a tapered pin to eliminate the deviation caused by the tolerance of each workpiece hole.
Select the compression spring to move from the beginning of the positioning contact with the workpiece.

Precautions of Round Wire Springs

Precautions for use of Round Wire Springs
Operating temperature of Round Wire Springs
SWP-A……Normal temperature (0~40℃)
Stainless steel……-10~100℃
Spring oil tempered steel wire……Normal temperature (0~40℃)
*If the spring is used under conditions exceeding the above temperature, the load value may decrease due to 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.
* Heat-resistant springs can also be used. For details, refer to the Plastic Mold Components Catalog.
Stainless steel springs are also magnetic. Please be careful.

Frequently asked question (FAQ)

Question: How long is the life of a basic round wire coil spring?
Answer: Unfortunately, there are no specific test values as reference regarding the life of a round wire coil spring because there is individual difference to a certain extent and the installation conditions are complicated.
The usage count varies with the 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..
Question: What are the JIS standards for general spring-related materials?
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: What influence will the usage without a spring rail have on the spring?
Answer: The usage without a spring rail will cause buckling of the spring, bending of its body and other problems, leading to breakage due to high stress locally generated on the inner side of the bending part. To ensure the service life of the spring, install the spring using the shaft, outer diameter guide rail, etc.
※Basically, it is ideal to use the spring on the intermediate shaft of the inner diameter side guide rail, passing it through from the upper surface to the lower surface.
Question: What influence will the usage count of more than 300,000 times beyond the maximum displacement (when used close to the solid length) have on the spring?
Answer: The usage count of more than 300,000 times beyond the maximum displacement (when used close to the solid length) will cause high stress breakage above the calculated value on the section. In addition, near the solid length, the effective coil part will gradually get close and the spring constant will increase. Therefore, be sure to use within the allowable displacement Fmax.(mm).
Question: What is the difference between a piano steel wire spring and a hard drawn steel wire spring?
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.
