A2 Stainless Steel Compression Springs — Reliable Elastic Force for Every Application

When a worn-out spring causes equipment downtime or a DIY project stalls because the right size is impossible to find, engineers and makers alike need a dependable source of precision-wound compression springs. These A2 stainless steel compression springs with 1.5mm wire diameter are designed for professionals, hobbyists, and maintenance technicians who demand consistent performance across a wide range of assemblies.

Each spring is wound from 1.5mm diameter A2 (304) stainless steel wire, offering an outer diameter (OD) range of 9–15mm (approximately 0.35–0.59 in) and free lengths from 10mm to 120mm (approximately 0.39–4.72 in). The closed-end coil geometry ensures stable seating and even load distribution across the full compression stroke.

These small compression springs for industrial equipment are well-suited for use in door mechanisms, curtain hardware, precision instruments, electrical enclosures, and 3D printer heated beds. They also serve as reliable replacement compression springs for automotive components, valve assemblies, and light-duty machinery where corrosion resistance and consistent spring rate are critical.

🔧 Compatibility: Suitable for standard spring seats accepting OD 9–15mm. Verify free length and spring rate against your application before ordering. Sold in packs of 10 pcs.

✅ Key Features of These A2 Stainless Steel Compression Springs

🔩 A2 (304) Stainless Steel Wire

Wound from 1.5mm A2 stainless steel wire, delivering corrosion resistance, abrasion resistance, and stable mechanical properties across a broad temperature range.

📐 Precise OD Range 9–15mm

Seven outer diameter options (9, 10, 11, 12, 13, 14, 15mm) allow exact fitment into existing spring pockets without modification.

📏 Multiple Free Lengths 10–120mm

Available in lengths from 10mm to 120mm, covering short-stroke actuators through longer travel mechanisms in a single product family.

⚡ Consistent Spring Rate & Resilience

Closed-end coil winding maintains a stable spring rate throughout the compression cycle, ensuring repeatable force output and long service life.

🛡️ Anti-Rust & Heat-Resistant Finish

304 stainless steel construction resists rust, oxidation, and mild chemical exposure, making these springs suitable for both indoor and outdoor environments.

📦 Convenient 10-Piece Packaging

Each order ships in a 10-piece pack, ideal for stocking spare parts, prototyping multiple assemblies, or completing repair jobs without over-ordering.

❓ Frequently Asked Questions

How do I choose the correct outer diameter for my application?

Measure the inner diameter of your spring pocket or housing, then select a spring OD that is 0.5–1mm smaller than the pocket ID to allow free movement. For a shaft-guided spring, measure the shaft OD and choose a spring ID (OD minus twice the wire diameter) that clears the shaft by at least 0.5mm.

What is the inside diameter of each spring size?

The inside diameter equals the outer diameter minus twice the wire diameter (1.5mm × 2 = 3mm). So: OD 9mm → ID 6mm; OD 10mm → ID 7mm; OD 11mm → ID 8mm; OD 12mm → ID 9mm; OD 13mm → ID 10mm; OD 14mm → ID 11mm; OD 15mm → ID 12mm.

Are these springs strong enough for load-bearing mechanical assemblies?

These 1.5mm wire compression springs provide moderate spring rates suitable for light-to-medium load applications such as valves, latches, electrical contacts, and instrument mechanisms. For heavy-duty or high-cycle industrial presses, consider a larger wire diameter or die spring. The exact load capacity depends on the selected OD and free length — contact us to confirm if you have specific force requirements.

How corrosion-resistant are A2 stainless steel springs?

A2 (304) stainless steel offers excellent resistance to atmospheric corrosion, fresh water, mild acids, and most organic compounds. It is suitable for outdoor, humid, and lightly corrosive environments. For marine or chloride-rich environments, A4 (316) stainless steel would be a more appropriate choice.

Are these springs compatible with 3D printer heated beds?

Yes. Small compression springs in the 9–15mm OD range and 10–50mm length are commonly used to level and support 3D printer heated beds. Select a free length that provides the desired pre-load travel for your bed adjustment range. The stainless steel construction also handles the elevated temperatures near heated beds without significant relaxation.

How is the free length measured?

Free length is the overall length of the spring in its natural, unloaded state — not compressed or stretched. This is the dimension listed in the variant options (e.g., 10mm, 15mm, 20mm). Always compare the free length to the available travel in your assembly to ensure the spring can compress to the required working length without going solid (coil-bound).

Can I order a custom size not listed in the variants?

The listed variants cover OD 9–15mm with free lengths from 10mm to 120mm. If you need a size outside these ranges or a different wire diameter, please contact us through the store's message system with your required wire diameter, OD, free length, and quantity — we can advise on availability.
