Product Info

Choosing the right spring type—compression, extension, torsion, or leaf—improves safety, performance, and equipment durability in industrial systems. Learn how to select the ideal spring based on load, environment, and application.


■ Types of Springs and Their Suitable Applications

1. Compression Springs
✅ Description: Coiled springs that compress under load and return to shape when released.
✅ Applications: Shock absorbers, machinery, automotive engines, electronics.
📌 Best for: Load-bearing uses like engine valves, bumpers, and appliances.

2. Extension Springs
✅ Description: Stretch under tension and contract when force is removed.
✅ Applications: Garage doors, retractable systems, gym equipment.
📌 Best for: Tensile force uses such as door mechanisms and counterbalances.

3. Torsion Springs
✅ Description: Work by twisting along an axis to provide rotational force.
✅ Applications: Hinges, clips, suspension.
📌 Best for: Applications needing torque like furniture hinges and paper clips.

4. Leaf Springs
✅ Description: Layered steel strips designed for heavy loads and shock absorption.
✅ Applications: Trucks, heavy vehicles, machinery.
📌 Best for: High-impact environments and heavy-load suspensions.


■ Key Factors in Spring Selection

1. Material Selection
- Stainless Steel: For corrosion resistance
- Carbon Steel: For strength
- Alloy Steel: For high-heat durability

2. Load & Size Matching
- Ensure proper coil diameter, spring rate, and length for safety and functionality.

3. Environmental Conditions
- Use Inconel or stainless steel in high-heat or corrosive settings.

4. Cycle Life & Durability
- For high-use applications, choose heat-treated or fatigue-resistant springs.
