Conical Extension Spring

The conical extension spring is designed with a tapered winding structure (narrow at one end and wider at the other), enabling a gradual and linear change in tensile force during extension. This results in smooth rebound performance, stable elasticity, and high resistance to tensile fatigue.

Compared with conventional straight extension springs, the conical extension spring offers a more controlled force transition and improved adaptability for special traction and non-standard mounting structures.

Customization options include:

• Hook and loop styles
• Taper ratio (cone structure)
• Coil quantity
• Maximum extension length
• Dimensional tolerance requirements

It is widely used in:

• Precision instruments
• Fitness equipment
• Door and window hardware
• Automation systems
• Non-standard transmission and traction components

Even under long-term high-frequency operation, it maintains stable performance without easy fatigue failure.

Our professional team responds within 12 hours to customer inquiries, ensuring clear communication on specifications, quantities, delivery schedules, and export compliance requirements.

 

Within 3–5 working days, feasibility evaluation for customization is completed, along with:

• Free technical parameter support
• Product testing reports
• Accurate quotation analysis
• Optimal procurement planning assistance

Each conical extension spring project is handled with a structured pre-sales process to ensure efficient and reliable cooperation.
