Stainless Steel Compression Springs Spring Ø0.6mm/0.7mm/0.8mm wire , L= 10-50mm

Wire diameter directly affects spring stiffness (spring rate) and load capacity. A thicker wire (0.8mm) produces a stiffer spring with higher load capacity, while a thinner wire (0.6mm) gives a softer, more compliant spring. Match the wire diameter to your required force range — if you need a light return force for a small switch, 0.6mm is typically sufficient; for heavier mechanisms, choose 0.7mm or 0.8mm.

The outer diameter (OD) of the spring should be slightly smaller than the inner diameter of the pocket or bore it sits in — typically 0.2mm to 0.5mm clearance is sufficient for free movement without binding. For a shaft-guided spring, the inner diameter (ID ≈ OD minus 2× wire diameter) should be slightly larger than the shaft diameter.

Free length is the uncompressed length of the spring. Choose a free length longer than your required working length so the spring is under compression in its installed position. A common rule of thumb is to select a free length approximately 20–30% longer than the compressed working length to ensure adequate preload and travel.

Yes. Stainless steel offers good corrosion resistance in most ambient and mildly humid environments. For prolonged exposure to saltwater, strong acids, or highly corrosive chemicals, additional protection or a different alloy may be required. For typical indoor DIY, electronics, and light outdoor use, stainless steel is a reliable choice.

Yes — small compression springs in the 0.6mm–0.8mm wire range are commonly used in 3D printer extruder tensioners, bed leveling mechanisms, and robotic gripper return systems. Select the OD and free length that match your design's spring seat dimensions and required travel.

The inner diameter is approximately equal to the outer diameter minus twice the wire diameter. For example, a spring with OD 6mm and wire diameter 0.6mm has an approximate ID of 4.8mm. Use this to check shaft clearance when the spring is guided on a pin or rod.
