Compression Springs — 16–19mm OD, 20–200mm Length for Reliable DIY Automation

When a mechanical assembly loses its return force or a jig fails to hold consistent pressure, the culprit is almost always an undersized or worn compression spring. Makers, workshop technicians, and automation hobbyists who need a dependable, drop-in replacement will find these compression springs sized precisely for the job — without having to order custom parts or wait on specialty suppliers.

Each spring is wound from 3mm wire diameter steel, with outer diameters spanning 16mm, 17mm, 18mm, and 19mm (approximately 0.63"–0.75"). Body lengths range from 20mm to 200mm (roughly 0.79"–7.87"), giving you the flexibility to match the exact free-length your application demands. Available individually or in economical 3-piece sets.

These compression springs are well-suited for DIY linear actuator builds, 3D printer bed-leveling assemblies, custom jig and fixture clamping systems, small robotics return mechanisms, and general-purpose spring replacement in light machinery and automation rigs.

⚙️ Compatibility: Fits standard spring pockets and guide rods designed for 16–19mm OD compression springs. Verify your bore/pocket inner diameter and free-length requirement before ordering.

✅ Key Features of These Compression Springs

📐 Wide Size Range

Four outer diameters (16, 17, 18, 19mm) combined with 14 length options (20–200mm) cover the most common DIY and light-industrial spring pockets without custom ordering.

🔩 3mm Wire Diameter

Consistent 3mm wire gauge across all variants ensures predictable spring rate behavior and straightforward substitution in existing designs.

🔄 Reliable Return Force

Wound to maintain consistent compression and extension cycles, making these springs dependable for repetitive-motion applications such as clamping fixtures and actuator returns.

🛡️ Corrosion-Resistant Finish

Surface treatment helps resist oxidation in typical workshop and indoor automation environments, extending service life compared to bare steel alternatives.

📦 Single or 3-Piece Packs

Order 1 piece for a quick repair or 3 pieces for a project build or spare-parts stock — both options available across the full size matrix.

🔧 Drop-In Replacement Ready

Standard metric dimensions make these springs straightforward replacements in 3D printers, robotics frames, jig assemblies, and light machinery without modification.

❓ Frequently Asked Questions

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

Measure the inner diameter of your spring pocket or the outer diameter of your guide rod. The spring's OD should be slightly smaller than the pocket bore (typically 0.5–1mm clearance) and larger than the guide rod OD. For example, if your pocket bore is 17.5mm, a 16mm or 17mm OD spring is a good starting point.

What free length should I select?

Free length is the uncompressed length of the spring. Choose a free length that is longer than your required working length by the amount of compression travel you need. For instance, if you need 10mm of travel and your working length is 30mm, select a spring with a free length of at least 40mm.

Are these springs strong enough for clamping fixtures?

These springs are designed for light-to-medium duty applications such as DIY jigs, 3D printer bed leveling, and small automation return mechanisms. For heavy industrial clamping requiring high spring rates, please contact us to confirm suitability before ordering.

How corrosion-resistant are these springs?

The springs feature a surface treatment that provides resistance to light oxidation in typical indoor workshop environments. They are not recommended for prolonged exposure to moisture, chemicals, or outdoor conditions without additional protection such as lubrication or coating.

Can I use these springs in a 3D printer bed-leveling system?

Yes. The 16mm and 17mm OD variants in shorter lengths (20–30mm) are commonly used in 3D printer bed-leveling assemblies. Verify the OD fits your printer's spring pocket and that the free length matches your bed gap requirements before ordering.

What is the difference between the 1 Pcs and 3 Pcs options?

The 1 Pcs option is ideal for single-unit repairs or testing a size before committing to a larger quantity. The 3 Pcs pack offers a lower per-unit cost and is suited for project builds, symmetric assemblies (e.g., four-corner bed leveling), or keeping spares on hand.

Are the spring dimensions metric or imperial?

All dimensions are metric. Wire diameter is 3mm, outer diameters are 16–19mm, and lengths are listed in millimeters (20mm–200mm). Approximate inch equivalents: OD 0.63"–0.75", lengths 0.79"–7.87".

How do I confirm compatibility before purchasing?

Check your existing spring's wire diameter, outer diameter, and free length using a caliper. Match those measurements to the variant options listed above. If you are unsure, feel free to contact us with your measurements and application details — we are happy to help you select the right size.
