Spring Steel Compression Y Type Pressure Spring Wire Diameter 0.3 To 0.9 mm Description

  1. Performance
    • Gentle, Progressive Force Curve – Y-type pressure geometry combined with fine wire diameters Ø0.3 – 0.9 mm delivers low-to-medium spring rates (≈ 0.02 – 0.80 N mm⁻¹). Force builds smoothly along the stroke, cushioning delicate components while ensuring reliable return.
    • High-Elasticity Metallurgy – Options include cold-drawn music wire (ASTM A228) for maximum energy density or 304/316 stainless for corrosion-critical environments. Both undergo oil tempering and dual stress-relief at 250 °C, achieving 1 300 – 1 750 MPa tensile strength with <2 % permanent set after 100 000 cycles.
    • Versatile Dimensions – Outer diameters Ø3 – 15 mm and free lengths up to 200 mm support miniature tactile buttons through to light shock-absorbing mounts. Variable-pitch or conical coils can be specified for progressive load curves or shortened solid heights.
    • Stable Across Temperatures – Modulus variation remains within ±3 % from −40 °C to +120 °C; optional heat stabilization to 300 °C keeps load drift below 3 % for continuous high-temperature duty.
  2. Application Scenarios & Assembly Requirements
    • Precision Returns – Ideal for microswitches, syringe pumps, camera shutters, and laboratory pipettes where low preload prevents seal damage or trigger fatigue.
    • Light Shock Absorption – Serves as miniature bump-stops in robotics joints, drone landing gear, sensor probes, and wearable devices, dissipating kinetic energy without harsh recoil.
    • Assembly Guidelines
    – Guide Clearance: bore ID = spring OD + 0.10 × wire Ø to avoid side-load buckling.
    – Working Stroke: cap compression at 80 % of solid height to maintain ≥ 95 % initial load over one million cycles.
    – End Style: squared & ground ends ensure axial load concentricity; closed-unground ends suit plastic seats with generous pockets.
    – Custom Profiles: barrel or telescopic versions mitigate resonance or allow nesting where axial space is limited.
  3. User-Friendly Operation
    • Pre-Scragged & Ready – Each spring is compressed to solid during production and re-set, so catalog forces are valid immediately—no run-in period required.
    • Clean Handling – Stainless variants withstand ultrasonic or solvent cleaning for sterile builds; carbon-steel versions arrive lightly oiled in anti-static trays to prevent tangling.
    • Quick Identification – Epoxy color dots on one coil encode wire size and spring rate, speeding up line-side sorting and maintenance swaps.
    • Tool-Free Installation – Small sizes can be seated by fingertip pressure; longer coils slide over simple mandrels—no specialty compressors or lubricants necessary.
  4. Quality & Longevity
    • ISO 9001 & IATF 16949 Manufacturing – Statistical process control on wire drawing, coil pitch, and heat treatment holds force tolerance to ±6 % and free-length tolerance to ±0.5 mm.
    • Proven Fatigue Life – Laboratory tests show <4 % load decay after 1 000 000 cycles at 60 % solid height; shot-peened surfaces reveal no micro-cracks under metallography.
    • Surface Protection Choices – Passivation (ASTM A967), black oxide, clear zinc, or PTFE dry-film coatings (≤ 8 µm) extend neutral salt-spray resistance to 72 – 120 h without altering spring rate.
    • Full Traceability – Laser-etched batch codes link each spring to 3.1 material certificates, load/deflection graphs, and RoHS/REACH compliance records, guaranteeing predictable performance for OEM, medical, and aerospace applications.
