Spiral Flat Wire Coil Spring – Constant Force Tension 0.7–1.5mm
Spiral Flat Wire Coil Spring – Constant Force Tension 0.7–1.5mm
Spiral Flat Wire Coil Spring – Constant Force Tension
This high-quality spiral flat wire coil spring is engineered from premium 60Si2Mn alloy spring steel, delivering consistent torque output across multiple rotation angles. Whether you're building, repairing, or upgrading mechanical assemblies, this constant-force vortex spring is a reliable component for bench drills, clock mechanisms, retractable tools, and other torque-driven applications.
Key Features
- Proportional Torque: Deformation angle is directly proportional to torque output, ensuring smooth, predictable performance across the full range of motion.
- High Torque Capacity: Designed for mechanisms requiring sustained multi-angle torque — ideal for long-duration operational cycles.
- Fatigue Resistant: Built to withstand repeated winding and unwinding cycles without loss of spring force or structural integrity.
- Premium Spring Steel: Made from 60Si2Mn high-quality alloy spring steel for superior elasticity, durability, and corrosion resistance.
- Versatile Sizing: Available in wire thickness from 0.7 mm to 1.5 mm and extended lengths from 680 mm to 1540 mm — choose the exact specification you need.
- New Condition: Each spring is brand new and inspected for quality before shipping.
