Compression Spring CS=1mm — Zinc-Plated Steel, OD 11–16mm, Reliable Elastic Return Force

When a project demands a compact, consistent spring that won't corrode or fatigue prematurely, finding the right wire diameter and outer diameter combination can be frustrating. These CS=1mm Y-type compression springs are designed for makers, engineers, and workshop professionals who need a dependable elastic component across a wide range of mechanical assemblies.

Each spring is formed from 1mm wire diameter (CS=1mm) zinc-plated steel, following a standard cylindrical (Y-type) coil geometry. Outer diameters span 11mm to 16mm (~0.43" to 0.63"), and free lengths range from 60mm to 100mm (~2.36" to 3.94"), giving you precise control over spring rate and travel distance. The zinc plating provides a corrosion-resistant barrier suited to indoor mechanical environments.

Typical use cases include compression spring replacements in tool jigs and fixtures, return-force mechanisms in DIY automation projects, and load-bearing cushioning in light-duty industrial equipment. These springs are also well-suited for compression spring OD 12mm applications in 3D printer extruder assemblies and small pneumatic valve returns.

🔧 Compatibility: Suitable for standard spring seats and bores accepting OD 11–16mm cylindrical compression springs. Verify bore clearance and seat depth against your selected variant's OD and free length before ordering.

✅ Key Features of These Compression Springs

🔩
CS=1mm Wire Diameter

Consistent 1mm wire cross-section delivers a predictable spring rate across all OD and length variants, reducing guesswork in load calculations.

📐
Wide OD Range: 11–16mm

Six outer diameter options (11, 12, 13, 14, 15, 16mm) let you match the spring to your bore or seat without custom fabrication.

📏
Five Length Options: 60–100mm

Free lengths from 60mm to 100mm in 10mm increments give you fine-grained control over travel and preload in your assembly.

🛡️
Zinc-Plated Corrosion Resistance

The zinc coating protects the steel coil from surface oxidation in typical indoor workshop and mechanical environments.

🔄
Y-Type Cylindrical Coil Geometry

Standard cylindrical (Y-type) form ensures even load distribution along the coil axis and compatibility with flat spring seats.

📦
Flexible Pack Quantities

Available in 1, 5, 10, and 20-piece packs — order a single piece to test fit or stock up in bulk for ongoing production runs.

❓ Frequently Asked Questions

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

Measure the bore or housing inner diameter your spring must fit inside — the spring OD should be 0.5–1mm smaller than the bore for smooth travel. For free length, select a value that gives you the desired compressed and extended positions with adequate preload. Use the variant selector to pick your OD (11–16mm) and length (60–100mm) combination.

What load can a CS=1mm spring handle?

With a 1mm wire diameter, these springs are designed for light-duty applications — typically suitable for return-force mechanisms, small fixtures, and light clamping tasks. Exact load capacity varies by OD and free length. If you need precise spring rate data for your variant, contact us to confirm.

Are these springs corrosion-resistant for outdoor use?

The zinc plating provides good protection against surface oxidation in dry indoor environments and light-humidity conditions. For prolonged outdoor exposure or wet environments, additional sealing or a stainless steel alternative is recommended. These springs are best suited for indoor mechanical and workshop applications.

Are these compatible with 3D printer or automation assemblies?

Yes. The cylindrical Y-type geometry and standard OD sizing make these springs compatible with many 3D printer extruder return mechanisms, small pneumatic valve returns, and DIY automation jigs. Verify the OD and free length against your assembly's spring seat dimensions before ordering.

Can I order a single piece to test fit before buying in bulk?

Absolutely. Each size combination is available in a 1-piece pack so you can verify fit and function in your assembly before committing to a 5, 10, or 20-piece order. Simply select your OD, length, and "1 pcs" quantity in the variant selector.

What is the difference between the 1, 5, 10, and 20-piece packs?

All packs contain identical springs — the only difference is quantity and per-unit cost. Larger packs offer a lower per-piece price, making them ideal for production runs, restocking a parts drawer, or projects requiring multiple springs of the same specification.

How do I verify the spring rate before purchasing?

Spring rate for a cylindrical compression spring depends on wire diameter, OD, and number of active coils. With CS=1mm and ODs of 11–16mm, the spring rate will vary by variant. If you need a confirmed spring rate value for engineering calculations, please contact us with your selected OD and length and we will provide the specification.
