Frequently asked question (FAQ)

Question: What distinguishes the Strong Spring TM (Middle Load) from conventional coil springs?
Answer: The Strong Spring TM features a rectangular wire cross-section, which increases load capacity in limited spaces compared to standard round-wire coil springs. Its optimized geometry ensures better stress distribution and consistent performance under medium-load conditions.
Question: What materials are used in Strong Spring TM (Middle Load)?
Answer: It is manufactured from silicon-chromium steel for springs, providing excellent fatigue resistance, dimensional stability, and long-term reliability under repeated compression cycles.
Question: What size options are available for this spring?
Answer: Strong Spring TM is available in free lengths ranging from 10 mm to 350 mm and inner diameters from 4 mm to 38.5 mm, accommodating diverse mechanical installation requirements.
Question: What is the spring rate range, and why is it important?
Answer: The spring offers a precise spring constant ranging from 5.32 to 367.48 N/mm. This ensures predictable load response and reliable performance across different stroke lengths in medium-load applications.
Question: How is the Strong Spring TM protected against wear and corrosion?
Answer: The spring undergoes Red electrodeposition coating, which enhances corrosion resistance, reduces surface wear, and increases durability in industrial environments.
Question: What applications are best suited for Strong Spring TM (Middle Load)?
Answer: It is ideal for press dies, mold ejection systems, clamping mechanisms, and industrial automation equipment. It is also suitable for mechanical assemblies, fixtures, and motion control systems requiring repeatable, medium-load spring performance in compact spaces.
