This custom flat spiral spring (scroll spring) is specially engineered for servomotor position feedback cable retraction, widely matched with damper actuator systems. Manufactured from premium 60Si2MnA silicon-manganese spring steel, it delivers stable, consistent torque for automatic cable rewinding during full piston stroke movement.

Unlike ordinary 65Mn spring steel, 60Si2MnA features higher tensile strength, outstanding anti-relaxation performance and superior cyclic fatigue resistance, making it ideal for long-term continuous industrial operation with repeated winding & unwinding cycles. Our spring is strictly produced per client technical specifications, with precise segmented winding structure to maintain smooth tension without cable stretching or jamming.

Key Technical Specifications

Raw Material: 60Si2MnA alloy spring steel strip
Strip Dimension: 2mm thickness × 39mm width
Total effective turns: 23 turns (13 tightly wound base turns + 10 spaced working turns)
Actual max tightening rotation per full stroke: 5.6 turns
Inner first coil diameter: 40mm | Drive shaft matching diameter: 29mm
Outer fixing pin diameter: 10mm | Inner straight hook length: 25mm
Matching housing inner diameter: 275mm
Surface finish: Black oxide anti-rust treatment (custom paint/Dacromet available)
Working function: Automatically rewind position feedback cable of servomotor rod

Structural Design Features

Segmented winding layout: 13 inner compact base turns stay fully attached during operation to provide stable baseline torque; 10 outer spaced turns serve as flexible working section for stroke retraction
Precision formed inner & outer hooks: Standard hook size fits housing fixing pin and motor drive shaft tightly, avoiding slip or fracture under torsion
Smooth strip edge machining: No burrs to scratch position cable during retraction, protecting cable integrity
Customizable dimensions: We support full customization of strip thickness, width, total turns, hook sizes and torque curves to match different servomotor & damper assemblies

Application Scenarios

Damper servomotor position feedback cable retraction system
Industrial actuator linear position sensing cable reel
Valve control motor automatic cable winding mechanism
Construction & hydraulic equipment servo reset assemblies
