Compression Spring Pressure Spring A2 Stainles Steel Wire Dia 1.4mm Ø 16mm-25mm

Measure the bore diameter of your housing — the spring OD should be slightly smaller than the bore to allow free movement. Then measure the available travel distance and required preload to determine the free length. Use the variant dropdowns to select the OD (16–25 mm) and free length (10–100 mm) that match your assembly.

The ID is calculated as: ID = OD − (2 × wire diameter). For example, the 16 mm OD spring has an ID of approximately 13.2 mm, and the 25 mm OD spring has an ID of approximately 22.2 mm. This determines the maximum shaft diameter the spring can slide over.

Yes. 304 (A2) stainless steel provides good resistance to atmospheric corrosion, moisture, and mild chemical exposure. These springs are appropriate for outdoor enclosures, marine-adjacent applications, and food-adjacent equipment where rust is a concern. For highly aggressive chemical environments, consider 316 stainless steel instead.

Yes. The 1.4 mm wire diameter provides a firm but compressible spring rate suitable for bed leveling on most FDM printers. The stainless steel construction resists heat from the heated bed better than carbon steel alternatives. Select a free length that matches your printer's standoff height — typically 15–25 mm for most bed leveling applications.

For the same wire diameter and OD, a shorter free length (fewer active coils) produces a stiffer spring with a higher spring rate, while a longer free length (more active coils) produces a softer spring with a lower rate. If you need a specific spring rate, contact us with your load and deflection requirements for guidance.

The 2-piece pack is ideal for single repairs or prototyping where you only need a small quantity. The 10-piece pack offers a lower per-unit cost and is suited for batch production, stocking spare parts, or projects requiring multiple springs of the same size. Both options ship the identical spring — only the quantity differs.

Yes, stainless steel springs can be used in housings made of carbon steel, galvanized steel, aluminum, or plastic. There is no galvanic corrosion concern in most dry or indoor environments. In wet environments with dissimilar metals, ensure adequate sealing or use compatible materials throughout the assembly.

The listed variants cover the most common sizes for 1.4 mm wire diameter springs. If you require a size outside the available options — such as a different OD, a longer free length, or a specific spring rate — please contact us with your specifications and we will advise on availability or custom options.
