Prestressed Power Spring

Material SUS 301, Steel Strip 　Thickness 0.04~1.2mm 　Width 2.5~90mm 　Length Customization 　Force Customization 　Type Customization Prestressed Power springs are made of rectangular section material, are wound flat, and have either special retaining holes or bends on both ends. As the length-to-thickness ratio (L/t) increases, the spiral space between coils increases rapidly. To reduce the space required and maintain a reasonable amount of deflection (turns), prestressed power springs are retained in some type of housing or case in application.
