When a project demands consistent return force, precise load bearing, or vibration dampening in a compact form factor, finding the right compression spring can be frustrating — wrong wire gauge, wrong free length, or a material that corrodes within weeks. These 1.4mm wire diameter stainless steel compression springs are engineered for makers, engineers, and maintenance professionals who need dimensional accuracy and corrosion resistance in a single, dependable component.
Each spring is formed from 1.4mm wire diameter stainless steel, with outer diameters ranging from 10mm to 25mm (approximately 0.39 in to 0.98 in) and free lengths spanning 10mm to 200mm (approximately 0.39 in to 7.87 in). The coil geometry delivers a consistent spring rate across the compression range, with closed and ground ends on applicable sizes for stable seating.
Typical use cases include compression spring replacements in mechanical assemblies, return-force elements in jigs and fixtures, cushioning components in 3D printer Z-axis beds, and load-bearing inserts in custom enclosures or valve mechanisms — all scenarios where a stainless steel compression spring with a defined wire diameter and outer diameter is required for repeatable performance.
Formed from stainless steel wire for resistance to oxidation and moisture, extending service life in exposed or humid environments.
Consistent wire gauge across all variants ensures predictable spring rate and load capacity for engineering-grade applications.
Outer diameters from 10mm to 25mm and free lengths from 10mm to 200mm cover a broad spectrum of mechanical design requirements.
Available in packs of 1, 5, or 10 units — order the quantity that matches your project scope without overstocking.
Uniform coil pitch and closed ends provide stable seating and repeatable compression-extension cycles across the spring's rated travel.
Suited for 3D printer beds, valve assemblies, jig fixtures, electronic enclosures, and general mechanical return-force applications.

Measure the bore or housing your spring will seat in to determine the maximum allowable outer diameter — select an OD slightly smaller than the bore for clearance fit. For free length, measure the uncompressed gap the spring must fill, then account for the required compressed length at working load. This product offers OD options from 10mm to 25mm and free lengths from 10mm to 200mm to cover most standard mechanical configurations.
Spring rate varies by outer diameter and free length combination. Because rate is a function of wire diameter, coil diameter, and number of active coils, each size variant will have a different rate. If you need a specific spring rate value for your design, please contact us with your selected variant dimensions and we can provide further guidance.
Yes. These springs are made from stainless steel, which provides good resistance to oxidation, moisture, and mild chemical exposure. They are suitable for use in humid environments, outdoor enclosures, and applications where carbon steel springs would corrode prematurely. For highly aggressive chemical environments, please confirm material compatibility with your specific media.
These compression springs are general-purpose components compatible with any mechanical assembly that requires a coil spring with 1.4mm wire diameter and OD between 10mm and 25mm. Common applications include 3D printer bed leveling, valve return mechanisms, jig and fixture clamping, electronic enclosure latches, and light industrial automation. No special tools are required for installation — springs are simply seated in their housing or over a guide rod.
Pack quantities of 1, 5, or 10 are available depending on the size variant. Smaller free-length springs (10mm–50mm) are typically available in packs of 10, mid-range lengths (60mm–100mm) in packs of 5, and longer springs (120mm–200mm) in packs of 1. Select the variant that matches both your dimensional requirements and the quantity you need for your project.
Standard stainless steel compression springs are generally suitable for temperatures up to approximately 250°C (480°F) depending on the alloy grade. For applications exceeding this range or involving cryogenic conditions, please contact us to confirm suitability before ordering.
A larger outer diameter with the same wire diameter results in a lower spring rate (softer spring), while a smaller outer diameter produces a higher spring rate (stiffer spring) for the same free length. Choose the OD that fits your housing geometry first, then verify the resulting spring rate meets your load requirements. If you need help selecting between sizes, contact us with your load and deflection specifications.
