Frequently asked question (FAQ)

Question: What is a coil spring?
Answer: A coil spring is a mechanical device made from a wound wire in a helical shape, designed to store and release energy, absorb shock, or maintain a force between contacting surfaces. Commonly used in automotive suspensions, machinery, and mechanical assemblies, coil springs offer flexibility, resilience, and stability.
Question: What is the purpose of coil spring?
Answer: The main purpose of a coil spring is to absorb mechanical energy and then release it when needed. In automotive applications, it supports vehicle weight and cushions road impacts. In machinery, it maintains tension, pressure, or spacing, contributing to smooth motion and load management.
Question: What are coil springs called in various industries?
Answer: Coil springs are also referred to as:
  • Compression springs (used to resist compression forces)
  • Tension springs (when designed to handle pulling forces)
  • Helical springs (based on their wound shape)
The naming may vary depending on the application and force direction.
Question: How are oil-tempered coil springs different from standard springs?
Answer: Oil-tempered coil springs are heat-treated and quenched in oil to enhance strength and durability. This process increases their fatigue resistance and load capacity, making them ideal for high-stress applications like industrial equipment or automotive suspensions.
Question: What materials are typically used for coil springs?
Answer: Coil springs are often made from carbon steel, stainless steel, or oil-tempered wire. The oil-tempered wire used in SWH-type coil springs offers superior toughness, wear resistance, and longevity, especially under cyclic loading conditions.
Question: Can coil springs be customized for specific loads or environments?
Answer: Yes. Coil spring dimensions—such as wire diameter, coil count, free length, and outer diameter—can be adjusted to meet specific force requirements, working loads, and environmental conditions.
Question: Are coil springs suitable for high-temperature environments?
Answer: Standard coil springs made from oil-tempered wire function well in moderate heat. For high-temperature environments, materials like Inconel or stainless steel are preferred to maintain structural integrity without softening or losing elasticity.
Question: How do you determine the right coil spring size?
Answer: Selecting the correct coil spring involves evaluating several parameters:
  • Load requirement
  • Spring rate (stiffness)
  • Operating environment
  • Space constraints
Accurate coil spring dimensions ensure optimal performance without overloading or premature fatigue.
Question: What are common signs of coil spring failure?
Answer: Symptoms of a failing coil spring include deformation, reduced load-bearing capacity, uneven force distribution, and visible cracks or corrosion. Regular inspection is crucial in high-cycle applications to avoid unexpected mechanical failures.
Question: How are coil springs maintained in industrial settings?
Answer: Although coil springs are low-maintenance, ensuring cleanliness, proper installation, and periodic inspection helps extend their life. In corrosive or high-load environments, protective coatings or using corrosion-resistant materials is recommended.
