Description

Compression Spring 32–40mm OD — Reliable Elastic Force for DIY & Mechanical Projects

When a worn-out spring causes a mechanism to fail mid-project, finding the right replacement quickly matters. Whether you are a hobbyist repairing a tool, a maker building a custom fixture, or a technician maintaining industrial equipment, these compression springs deliver consistent elastic force across a wide range of applications.

Each spring is wound from 3mm wire diameter steel, with outer diameters spanning 32mm to 40mm (approximately 1.26"–1.57") and free lengths ranging from 20mm to 100mm (approximately 0.79"–3.94"). The coil body features a uniform helical pitch with closed and ground ends for stable seating. Available in 1, 3, or 5-piece quantities to suit single repairs or batch builds.

Typical use cases include compression spring replacement for mechanical assemblies, spring-loaded jig and fixture design, and DIY repair of garden tools, latches, and valve mechanisms — all scenarios where a reliable compression spring with 32–40mm outer diameter is essential.

⚙️ Compatible with standard spring seats and bores sized for 32–40mm outer diameter. Verify free length and spring rate against your application before ordering.

✅ Key Features of These Compression Springs

📐Wide Size Range

Outer diameters from 32mm to 40mm and lengths from 20mm to 100mm cover a broad spectrum of replacement and design needs.

🔩3mm Wire Diameter

Consistent 3mm wire gauge across all variants ensures predictable spring rate and load-bearing performance.

🔄Closed & Ground Ends

Flat, ground end coils provide stable seating on flat surfaces, reducing lateral deflection under load.

📦Flexible Quantity Options

Choose 1, 3, or 5 pieces per order — ideal for single repairs, prototyping, or keeping spares on hand.

🛠️Versatile Application

Suited for mechanical assemblies, jigs, fixtures, latches, valves, and general DIY compression spring applications.

✔️Consistent Coil Geometry

Uniform helical winding maintains even load distribution and repeatable deflection across the full compression range.

❓ Frequently Asked Questions

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

Measure the bore or housing your spring sits in. The spring's outer diameter should be slightly smaller than the bore to allow free movement without binding. For a shaft-guided spring, the inner diameter (outer diameter minus twice the wire diameter) should clear the shaft with a small gap. Select from 32mm, 34mm, 35mm, 36mm, 38mm, or 40mm outer diameter options above.

How do I select the correct free length?

The free length should be longer than your required compressed length plus the desired travel (deflection). A common rule is to choose a free length at least 20–30% longer than the maximum compressed height in your assembly. Available lengths range from 20mm to 100mm in this listing.

What load or spring rate can I expect from these springs?

Spring rate depends on wire diameter, outer diameter, free length, and number of active coils. With a fixed 3mm wire diameter, shorter springs with smaller outer diameters will generally have higher spring rates. For precise load requirements, please contact us to confirm — spring rate data is available on request.

Are these springs corrosion resistant?

Corrosion resistance depends on the material and surface finish of the specific variant. If your application involves moisture, chemicals, or outdoor exposure, please contact us to confirm the material specification before ordering. For corrosive environments, a zinc-plated or stainless steel option is typically recommended.

Can these compression springs be used in outdoor or wet environments?

Suitability for outdoor or wet environments depends on the surface treatment of the spring. Standard carbon steel springs may develop surface oxidation over time when exposed to moisture. For outdoor or humid applications, verify the finish specification with us before purchasing.

Why should I order 3 or 5 pieces instead of just 1?

Ordering multiple pieces is cost-effective for projects requiring matched springs (e.g., parallel spring assemblies), for keeping spares on hand to avoid downtime, or for prototyping where you may need to test several lengths or diameters before finalising your design. Multi-piece packs offer a lower per-unit cost compared to single-piece orders.

How do I measure a spring I need to replace?

Measure three key dimensions: (1) the outer diameter with calipers, (2) the free length (uncompressed height), and (3) the wire diameter. Match these to the variant options in this listing. If your existing spring is worn or deformed, measure the housing bore and shaft diameter instead to determine the required outer and inner diameter range.

🛒 Select your size (wire dia. × outer dia.), length, and quantity above, then add to cart.
