Compression Spring Steel Coil — Reliable Elastic Force for Every Mechanical Assembly

When a project demands consistent return force and dimensional accuracy, undersized or mismatched compression springs cause premature failure, uneven load distribution, and costly rework. Engineers, robotics builders, and hands-on DIYers who need a dependable stock of compression springs in precise metric sizes will find this range an essential bench staple.

Each spring is wound from spring steel wire with a nominal diameter of 1.5 mm (0.059 in). Outer diameters span 19–30 mm (0.75–1.18 in) and free lengths range from 10–100 mm (0.39–3.94 in). Springs are sold in packs of 10 pieces, making it straightforward to keep spares on hand or prototype multiple configurations at once.

Typical use cases include compression spring for robotics end-effectors requiring controlled return travel, mechanical jig and fixture spring loading for consistent clamping force, and DIY tool and appliance repair where an exact metric compression spring replacement is needed.

⚙️ Compatibility: Suitable for spring housings, bores, and guide rods sized to accept OD 19–30 mm springs. Verify bore clearance and free-length travel before ordering.

✅ Key Features of These Compression Springs

🔩Spring Steel Wire
Wound from carbon spring steel for consistent elastic modulus and fatigue resistance across repeated compression cycles.

📐Precise Metric Sizing
Wire diameter 1.5 mm, OD 19–30 mm, free length 10–100 mm — select the exact dimension from the variant menu above.

🔄Closed & Ground Ends
Flat-ground end coils provide stable seating on flat surfaces and reduce lateral buckling under load.

📦10-Piece Pack
Each order ships as a pack of 10 identical springs, giving you spares for prototyping, repair, or batch assembly.

🛡️Corrosion-Resistant Finish
Springs carry a light surface treatment to resist oxidation during storage and normal indoor mechanical use.

🔧Wide Size Range
OD options from 19 mm to 30 mm and lengths from 10 mm to 100 mm cover a broad spectrum of mechanical design requirements in a single product family.

❓ Frequently Asked Questions

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

Measure the bore or housing inner diameter and subtract 0.5–1 mm for clearance to get your target OD. For free length, measure the available travel distance and add the compressed height you need. Select the matching Size variant from the dropdown above.

What material are these compression springs made from?

These springs are wound from carbon spring steel wire, which provides a good balance of tensile strength, elastic recovery, and cost-effectiveness for general mechanical applications.

Are these springs suitable for outdoor or wet environments?

The springs carry a light surface treatment that resists oxidation during storage and dry indoor use. For prolonged outdoor or high-humidity exposure, consider applying a compatible grease or selecting stainless steel springs instead.

Can I use these springs in robotics or automation equipment?

Yes. The consistent wire diameter and closed-end construction make these springs well-suited for robotics end-effectors, linear actuator return mechanisms, and sensor-mounting assemblies where repeatable spring force is required.

What is the difference between the OD sizes in this range?

Each OD step (19 mm, 20 mm, 21 mm … 30 mm) is a distinct spring wound to that outer diameter. Larger ODs generally produce higher spring rates at the same wire diameter and free length. Choose the OD that fits your housing bore with appropriate clearance.

How many springs are included per order?

Each order of a single variant includes 10 pieces of identical springs. If you need multiple sizes, add each size variant to your cart separately.

Can these springs be used as replacement parts for tools or appliances?

Yes, provided the replacement spring matches the original's wire diameter (1.5 mm), OD, and free length. Cross-reference your original part dimensions with the variant options above before ordering.
