TENSION (EXTENSION) SPRINGS
Precision Tension Spring Manufacturer in Faridabad, India
Tension springs, also known as extension springs, are tightly wound helical springs designed to work under tensile load. These springs store mechanical energy when stretched and apply a pulling force to return connected components to their original position. They are widely used in systems that require controlled return motion, consistent tension, and reliable performance over repeated cycles.
What Are Tension Springs?
Tension springs operate by resisting pulling forces. Unlike compression springs, they are manufactured with initial tension, meaning the coils are already under load even at rest. When the spring is stretched, it generates increasing resistance and delivers predictable return force once the load is released.
Tension springs are typically fitted with hooks, loops, or custom end configurations to suit specific mounting and functional requirements.
Applications of Tension Springs
Tension springs are used across a wide range of industrial and mechanical applications, including:
- Automotive assemblies such as throttle linkages, seat mechanisms, and brake systems
- Industrial machinery including conveyors, levers, and return mechanisms
- Garage doors, access systems, and hinged closures
- Agricultural and construction equipment
- Tools, fitness equipment, and mechanical devices
- Valves, switches, and motion control assemblies
Their ability to deliver consistent tensile force makes them essential in both light-duty and heavy-duty applications.
How Tension Springs Work
When a tensile load is applied, the spring stretches and stores energy in the form of elastic deformation. The resistance increases proportionally with extension, allowing controlled force delivery. Once the applied force is removed, the spring contracts back toward its original length, providing reliable and repeatable return action.
Key Design Parameters
At Surya Springs, tension springs are engineered based on precise application requirements, including:
- Free length and maximum extended length
- Required pulling force at defined extension
- Wire diameter and coil diameter
- Type of end fittings such as machine hooks, side hooks, or custom loops
- Expected operating cycles and fatigue life
- Material selection and surface finish based on environment and usage
Each parameter is carefully evaluated to ensure optimal performance and long service life.
