Compression Springs 1.8mm Wire OD 16mm — Reliable Load Control in 304 Stainless Steel

When your project demands a spring that holds its shape under repeated cycling, a loose or undersized wire diameter causes premature fatigue and unpredictable load behavior. Engineers, makers, and workshop professionals who need consistent spring force across a wide length range rely on precisely wound compression springs with a defined wire diameter and outer diameter. These 1.8mm wire diameter, 16mm outer diameter compression springs are designed to deliver repeatable performance in demanding mechanical assemblies.

Each spring is wound from 304 stainless steel wire with a wire cross-section (CS) of 1.8mm and an outer diameter (OD) of 16mm. Free lengths span from 10mm to 200mm (approximately 0.39 in to 7.87 in), giving you the flexibility to match the exact travel and load requirements of your application. The close-wound coil geometry provides uniform pitch and consistent spring rate across the full compression range.

Typical use cases include mechanical actuators requiring a 1.8mm wire compression spring for precise return force, DIY jig and fixture design where a 16mm OD stainless steel spring fits a standard bore, and industrial automation components needing a corrosion-resistant compression spring for outdoor or humid environments.

✅ Compatible with standard 16mm bore housings and guide rods up to approximately 12–13mm diameter. Verify free length and spring rate against your load requirements before ordering.

✅ Key Features of These 1.8mm Wire 16mm OD Compression Springs

🔩 304 Stainless Steel Construction

Wound from grade 304 stainless steel wire for strong corrosion resistance in humid, wet, and mildly acidic environments — a reliable choice over plain carbon steel springs.

📐 Precise Wire and OD Dimensions

Wire diameter 1.8mm, outer diameter 16mm — consistent across all length variants so you can swap lengths without redesigning your housing or guide rod.

📏 Wide Length Range: 10mm to 200mm

Choose the free length that matches your required travel and load. Lengths from 10mm (0.39 in) to 200mm (7.87 in) are available in a single product listing.

⚙️ Uniform Coil Pitch for Consistent Spring Rate

Close-wound coil geometry ensures a predictable spring rate and smooth compression stroke, reducing vibration and noise in mechanical assemblies.

📦 Flexible Quantity Options

Available in packs from 1 to 100 pieces. Order the exact quantity you need for prototyping, small-batch production, or stocking your workshop.

🛡️ Durable for Repeated Cycling

Stainless steel work-hardens slightly under load cycling, maintaining spring force over thousands of compression cycles in typical mechanical applications.

❓ Frequently Asked Questions

How do I choose the right free length for my application?

Measure the distance between the two surfaces the spring will sit between when the assembly is at rest (uncompressed). This is your required free length. Add the expected compression travel to confirm the spring will not reach solid height during operation. If you are unsure, select a length slightly longer than your measured gap and verify with a test fit.

What inner diameter guide rod can I use with a 16mm OD spring?

With an outer diameter of 16mm and a wire diameter of 1.8mm, the inner diameter is approximately 12.4mm. A guide rod of 10–12mm diameter is typically recommended to allow free movement without binding. Always leave 0.5–1mm clearance between the rod and the spring's inner diameter.

Is 304 stainless steel suitable for outdoor or wet environments?

Yes. 304 stainless steel offers good resistance to atmospheric corrosion, fresh water, and mild chemical exposure. It is widely used in outdoor fixtures, marine-adjacent applications, and food-processing equipment. For highly saline or chloride-rich environments, 316 stainless steel would provide superior corrosion resistance.

How do I calculate the spring rate for these compression springs?

Spring rate (k) depends on wire diameter, coil diameter, number of active coils, and material shear modulus. For a 1.8mm wire, 16mm OD spring, the rate varies with free length — shorter springs with fewer active coils have a higher spring rate. If you need a specific spring rate, please contact us with your free length and load requirements so we can confirm compatibility.

Can these springs be used in high-temperature environments?

304 stainless steel compression springs are typically rated for continuous use up to approximately 200°C (392°F). Above this temperature, the material may experience stress relaxation and reduced spring force over time. For higher-temperature applications, consider springs made from 17-7 PH stainless steel or Inconel alloys.

How do I select the right quantity for my order?

Select your required SIZE (CSxODxL) first, then choose the quantity (QTY) from the dropdown. Packs range from 1 piece up to 100 pieces. Ordering in larger quantities reduces the per-unit cost and ensures you have spares for maintenance or future builds.

Are these springs compatible with standard spring housings?

Yes. With a 16mm outer diameter, these springs fit standard 16mm bore spring housings and retainers commonly used in pneumatic cylinders, jigs, and mechanical assemblies. Always verify the bore diameter and depth of your housing against the spring's OD and free length before installation.

🛒 Select your SIZE (CSxODxL) and QTY above, then add to cart.
