Product Introduction
Xuanyu Springs supports custom-made non-standard parts for various double-hook tension springs. We can provide full technical support and flexible production solutions, from material selection and size design to surface treatment, according to your specific application needs.
A double-hook tension spring is an axially tensioning elastic element with hook-shaped structures at both ends. In its natural state, its coils are closely arranged; when subjected to axial tension, the spring stretches and stores energy, and quickly returns to its original shape after the external force is removed, thereby realizing functions such as traction, reset, tensioning, or force transmission.
These springs have a simple structure and are easy to install. They are widely used in mechanical equipment, automotive parts, home appliances, industrial equipment, and various occasions that require linear reset or constant force tension.

Advantages of Xuanyu Double Hook Tension Springs
1. High fatigue life and reliability
The springs are optimized in design and manufacturing process, and maintain stable mechanical properties under repeated stretching conditions, making them suitable for mechanical systems that operate in long-term cycles.
2. Flexible size and performance customization
It supports non-standard designs, and the wire diameter, outer diameter, free length, initial tension, etc. can all be adjusted as needed. A variety of materials and surface treatments are also available.
3. Hook reinforcement structure
The double hook section is reinforced and molded for a secure connection, preventing deformation or detachment under dynamic loads and improving overall safety.
4. Wide range of environmental adaptability
The appropriate material and surface treatment can be selected according to the usage scenario. For example, stainless steel or zinc plating is used in outdoor environments, while nickel or chrome plating is used in corrosive environments.
Main Application Scenarios
Mechanical equipment and automation: used for conveyor belt tensioning, valve reset, and safety mechanism linkage, etc.
Automotive industry: Used in components such as seat adjusters, throttle reset, and trunk supports.
Home appliances and furniture: Used in washing machine balancing devices, cabinet door buffers, and folding mechanism aids, etc.
Instruments and fitness equipment: used for applications such as tension adjustment, stroke control, and resistance simulation.
We can provide full-process support, from selection advice to customized production, based on your specific application needs. Please feel free to provide drawings or samples, and we will match you with the most suitable double-hook tension spring solution.
