Stainless Steel Constant Force Spring
Manufactured from pre-stressed spring steel strip, this constant force spring delivers nearly constant force throughout its working stroke. It is ideal for automatic retraction, counterbalancing, and constant tension applications in automation equipment, medical devices, and consumer electronics.
Manufactured from premium SUS301, SUS304, or high-carbon spring steel strip using precision heat treatment and coiling processes, this constant force spring provides excellent elastic recovery and highly consistent output force. Compared with conventional compression or extension springs, it maintains nearly constant pulling force over an extended working stroke, reducing force variation and ensuring smoother system operation. Its compact design minimizes installation space while delivering excellent fatigue resistance and corrosion resistance, making it suitable for continuous cycling applications. OEM customization is available for output force, strip width, thickness, and coil dimensions.
