Compression Spring 1.4mm Wire Dia Stainless Steel Springs Length Up To 100 mm

Measure the bore or housing your spring will sit inside, then select an outer diameter (OD) that provides a small clearance — typically 0.5mm to 1mm smaller than the bore. If the spring rides over a guide pin or shaft, the inner diameter (ID = OD − 2.8mm for 1.4mm wire) must be larger than the pin diameter. Available ODs range from 8mm to 25mm in this listing.

Free length is the uncompressed length of the spring. Choose a free length that, when compressed to your working height, still has coil clearance (coils should not be fully closed under normal load). As a starting point, your working deflection should be no more than 70–80% of the free length. Options in this listing range from 10mm to 100mm.

Yes. Stainless steel provides good resistance to rust and oxidation in humid, wet, and mildly saline environments. For highly aggressive marine or chemical environments, verify the specific stainless alloy grade meets your corrosion resistance requirements. Contact us to confirm the alloy grade if needed.

Load capacity depends on the specific outer diameter and free length combination selected. With a 1.4mm wire diameter, these are light-duty to medium-duty springs suited for mechanisms requiring moderate return force. For precise load and spring rate data for a specific variant, please contact us to confirm before ordering for load-critical applications.

Absolutely. The compact size range (OD 8–25mm, length 10–100mm) and consistent stainless steel construction make these springs well-suited for extruder arm return mechanisms, bed leveling assemblies, servo linkages, and other maker or robotics applications where a reliable, corrosion-resistant compression spring is needed.

Pack quantity varies by the length variant selected: shorter lengths (10mm–50mm) typically come in packs of 10 pieces; medium lengths (60mm–70mm) come in packs of 5 pieces (for some OD sizes) or 2 pieces; longer lengths (60mm–100mm for larger ODs) come in packs of 2 pieces. The exact quantity is shown in the variant name (e.g., "30mm & 10pcs" means 30mm free length, 10 pieces per pack).

Outer diameter (OD) is the overall width of the spring coil measured from outside edge to outside edge. Inner diameter (ID) is the clear opening through the center of the coil, calculated as OD minus twice the wire diameter. For these springs: ID = OD − 2.8mm. For example, an 8mm OD spring has an ID of approximately 5.2mm.
