Compression Springs 1.4mm Wire Dia — Reliable Elastic Force for Precision Applications

When a project demands consistent return force in a compact footprint, finding the right compression spring can be frustrating. Undersized wire snaps under load; oversized coils won't fit the housing. These 304 stainless steel compression springs are engineered for makers, engineers, and small-batch manufacturers who need dimensional accuracy and corrosion resistance in a single, ready-to-use component.

Each spring is wound from 1.4mm (0.055 in) wire diameter 304 stainless steel. Outer diameters span 20mm, 22mm, and 25mm (0.787–0.984 in), with free lengths ranging from 10mm to 50mm (0.39–1.97 in). The open-coil helical design provides linear spring rates suitable for light-to-medium duty elastic return applications.

Typical use cases include DIY mechanical assemblies requiring spring-loaded latches or plunger returns, robotics and automation fixtures needing repeatable elastic force, and small-batch manufacturing jigs where consistent spring geometry is critical for part alignment and ejection.

⚙️ Compatibility: Suitable for spring housings, guide rods, and plunger assemblies with bore diameters matching the selected OD variant. Verify free length and OD against your housing dimensions before ordering.

✅ Key Features of These 304 Stainless Steel Compression Springs

🔩 1.4mm Wire Diameter

Consistent wire cross-section across all variants ensures predictable spring rate and load capacity for light-to-medium duty applications.

📐 Three OD Options: 20 / 22 / 25mm

Select the outer diameter that fits your housing bore. Sizes span 0.787–0.984 in, covering a broad range of standard spring pockets.

📏 Free Lengths 10–50mm

Nine length options per OD group let you dial in the exact travel and preload your assembly requires without custom fabrication.

🛡️ 304 Stainless Steel Construction

304 grade stainless offers solid oxidation and corrosion resistance, making these springs suitable for humid environments and light outdoor exposure.

📦 Bulk Quantity Packs (10–100 pcs)

Order from 10 to 100 pieces per variant to match prototype runs or production batches, reducing per-unit cost at higher quantities.

🔄 Open-Coil Helical Design

Standard open-coil geometry provides linear deflection characteristics and allows visual inspection of coil spacing during assembly.

❓ Frequently Asked Questions

How do I choose the right OD and length for my application?

Measure the inner diameter of your spring housing or guide rod diameter first. The spring OD should be slightly smaller than the housing bore (typically 0.5–1mm clearance) or slightly larger than the guide rod. Then select a free length that gives you the desired preload and travel range within your assembly's compressed and extended limits.

What load can a 1.4mm wire diameter compression spring handle?

Load capacity depends on the OD, free length, and number of active coils — all of which vary by variant. As a conservative guide, 1.4mm wire springs in this OD range are suited for light-to-medium duty elastic return forces, typically in the range of a few Newtons to tens of Newtons depending on deflection. Contact us to confirm load data for your specific variant.

Are these springs corrosion-resistant enough for outdoor or humid environments?

304 stainless steel provides good resistance to atmospheric corrosion, moisture, and many mild chemicals. It is suitable for indoor humid environments, light outdoor exposure, and non-marine applications. For highly corrosive or saltwater environments, 316 stainless steel would be a more appropriate choice.

Are these compatible with standard spring guide rods or plunger assemblies?

Yes. The open-coil helical design is compatible with standard guide rods and spring pockets. Ensure the guide rod diameter is smaller than the spring ID (OD minus 2× wire diameter), and the housing bore is larger than the spring OD. For the 20mm OD variant, the approximate ID is 17.2mm; for 22mm OD, approximately 19.2mm; for 25mm OD, approximately 22.2mm.

Can I use these springs in robotics or automation fixtures?

Yes. These springs are well-suited for robotics end-effectors, gripper return mechanisms, sensor probe springs, and automation jig ejectors where repeatable elastic return force and dimensional consistency are required. The stainless construction also tolerates light cleaning agents used in automated assembly environments.

How do I decide between ordering 10 pcs vs. 100 pcs?

For prototyping or design validation, the 10-piece pack lets you test fit and function before committing to larger quantities. For production runs or stocking a workshop, the 50–100 piece packs offer a lower per-unit cost. All quantity variants ship the same spring specification — only the pack size differs.

What is the difference between the 20mm, 22mm, and 25mm OD variants?

The outer diameter determines which housing bore or guide rod the spring fits. A larger OD also generally means more coil material and a stiffer spring rate at the same wire diameter and length. Choose the OD that matches your housing geometry first, then select the length for the required travel and preload.
