About This Product
■A variety of compression springs that contribute to product miniaturization, quality improvement, and man-hour reduction.
CWS is an abbreviation for coiled wave spring, and it is a compression spring made of flat wire material that is especially suitable for static load applications. (A small “deflection (stroke)” can also handle dynamic loads.)
They are useful for downsizing products, improving quality, and reducing man-hours because they have high stability and parallelism in deflection when compressed, and because they require less installation space than regular compression springs.
In addition, by changing the number of threads and turns, the spring constant and load characteristics can be varied in a variety of ways, making it a spring with a high degree of freedom. For example, it is possible to create a compression spring with a large diameter and a weak load while maintaining stability in deflection.
We manufacture CWS using our own processing method, leveraging our many years of experience and know-how in manufacturing irregularly shaped wire springs.
■Size and weight reduction
The load can be stronger than normal compression springs, and the installation height can save space. Contributes to miniaturization of products.
■Stable deflection
The structure allows the entire spring to receive the load evenly, resulting in high stability and parallelism in deflection (stroke) during compression.
■Contribute to reduce activities
Disc springs and wave washers always produce offcuts, but CWS almost never produces offcuts, contributing to activities to reduce waste.
■Uses of CWS
It is used in a wide range of fields including automobile parts, medical equipment, industrial machinery, factory equipment, machine tools, and fishing gear. *Since the load is smaller than a disc spring, it cannot be simply replaced, but depending on the application, it can simplify the troublesome assembly.
■Replacement of wave washer
Wave washers are often used to finely adjust gaps and prevent rattling when assembling machines and equipment, apply preload to cushions and bearings, and prevent screws from loosening, but if they are pushed in too tightly, the washer may become plastically deformed. Have you ever? CWS allows for a larger amount of deflection than wave washers, reducing the risk of plastic deformation (sagging).
