When a mechanism fails because a spring is too stiff, too soft, or simply the wrong size, the entire project stalls. Engineers, hobbyists, and repair technicians who work with compact assemblies need a reliable source of accurately sized compression springs that fit without modification. These 10-piece Y type compression springs are designed for exactly that scenario — delivering consistent elastic force in a small footprint.
Each pack contains 10 compression springs manufactured from carbon steel wire with a diameter of 1.4 mm or 1.5 mm (approximately 0.055–0.059 in). The outer diameter spans 8–25 mm (approx. 0.31–0.98 in), and free lengths range from 10–50 mm (approx. 0.39–1.97 in) depending on the selected variant. The Y type coil geometry provides a balanced load-deflection curve suited to moderate-duty cyclic applications.
Typical use cases include spring-loaded button mechanisms in consumer electronics, return springs in small pneumatic or hydraulic valves, tension-relief components in 3D printer extruder assemblies, and replacement springs for precision instruments and hobby RC vehicles.
Wound from carbon steel wire for reliable elastic recovery and resistance to permanent set under repeated compression cycles.
Wire diameters of 1.4 mm and 1.5 mm combined with OD 8–25 mm and free lengths 10–50 mm give you a broad selection to match your exact bore and travel requirements.
The Y type winding profile delivers a smooth, progressive load curve — reducing shock loads and extending service life in cyclic applications.
Each order ships as a pack of 10 identical springs, giving you spares for prototyping, testing, or batch repairs without overstocking.
Uniform pitch spacing across the coil body ensures even load distribution and predictable deflection — critical for precision mechanisms and instrumentation.
Compatible with electronics, hobby robotics, 3D printer components, small valves, and general DIY assemblies requiring compact return or cushioning springs.

Start with three measurements: the bore or housing inner diameter (your spring OD must be slightly smaller), the shaft or guide rod outer diameter (your spring ID must be slightly larger), and the required travel or stroke (your free length minus compressed length). Match wire diameter to your load requirement — 1.4 mm wire suits lighter loads, while 1.5 mm wire handles moderately higher forces. Select the variant that best fits all three parameters.
Wire diameter directly affects spring stiffness (spring rate) and load capacity. A 1.5 mm wire spring is stiffer and can carry a higher load at the same deflection compared to a 1.4 mm wire spring of identical OD and free length. If your application requires a softer, more compliant spring, choose 1.4 mm; for a firmer return force, choose 1.5 mm.
These springs are made from carbon steel, which offers good mechanical properties but limited inherent corrosion resistance. For dry indoor environments — electronics, hobby assemblies, 3D printers — they perform reliably. If your application involves moisture, mild chemicals, or outdoor exposure, consider applying a light coat of machine oil or contact us to confirm suitability for your specific environment.
"Y type" refers to the coil winding geometry and end configuration of the spring. Y type compression springs feature a specific coil profile that produces a balanced, progressive load-deflection curve. This makes them well-suited for applications where a smooth, predictable force build-up is needed rather than a sharp, linear response — common in button mechanisms, valve returns, and precision instruments.
Yes. The compact OD range (8–25 mm) and short-to-medium free lengths (10–50 mm) make these springs a practical fit for 3D printer extruder tensioners, bed leveling assemblies, and small servo or linkage return mechanisms in hobby robotics. Verify the specific OD and free length variant matches your component's spring seat dimensions before ordering.
Each order of a single variant includes 10 identical springs. If you need a larger quantity for batch production, prototyping, or stocking purposes, simply add multiple packs to your cart. All springs within a pack are manufactured to the same nominal dimensions for consistent performance across your build.
Use a digital caliper for accuracy. Measure the outer diameter (OD) of the existing spring, the wire diameter (the thickness of the coil wire itself), and the free length (the uncompressed total length). Cross-reference these three values against the variant options above. If your existing spring is worn or deformed, measure the housing bore and shaft guide instead to determine the correct OD and ID range.
