High-Load, Precision Spring Performance
• Engineered to DIN 2093 “A, B, C” classifications, these conical disc springs deliver highly predictable load–deflection curves:
– Type A (0.2–1.25 mm thick) for light, accurate preload in miniature mechanisms
– Type B (1.25–6 mm) for general machine assemblies
– Type C (6–16 mm) for heavy shock absorption and bolted-joint compensation.
• Rolled from solution-annealed and work-hardened stainless steels (17-7 PH, 301, 304 or 316) then shot-peened, resulting in surface compressive stresses that raise fatigue life above 2 × 10⁶ cycles at 75 % of maximum deflection.
• Single-stack or series/parallel arrangements achieve forces from 50 N to >1 000 kN while maintaining spring rate tolerances to ±10 %; laser-engraved lot and load codes simplify field verification.
• Stainless construction resists chloride, humidity and many industrial chemicals from −200 °C to +350 °C, eliminating red-rust risk without the galvanic concerns of plated carbon steel washers.
Широкий, межотраслевой спектр применения
• Power Generation & Wind Turbines: Maintains constant bolt preload on tower flanges and gearbox covers despite temperature swings and vibration.
• Oil, Gas & Chemical Processing: Acts as live-loading elements behind gland followers, preventing leakage during thermal cycling and pressure fluctuations.
• Automotive, Rail & Off-Highway Equipment: Absorbs impact loads in suspension bushings, couplers and braking systems while withstanding road salt and de-icing agents.
• Precision Engineering & Robotics: Provides compact, high-force springs in overload clutches, ball-screw tensioners and servo-motor mounts where space is at a premium.
Установщик-дружественный, экономящий время
• Chamfered inner/outer edges avoid scoring during insertion over shafts or inside bores; orientation marks guide rapid stacking in series or parallel without manual measurement.
• Compatible with standard torque charts—simply substitute for flat washers and the spring action automatically compensates for joint settling and thermal expansion.
• Low creep stainless alloys hold height under sustained compression, reducing maintenance intervals compared with elastomeric or Belville stacks made from softer materials.
• Supplied individually, shrink-wrapped columns, or tape-on-reel for automated feeders; optional PTFE-free dry-film lubrication cuts insertion friction and galling on high-cycle assembly lines.
Проверенное качество и долгосрочная долговечность
• 100 % dimensional laser scanning checks thickness ±0.01 mm, cone angle ±0.25°, and parallelism ≤0.05 mm; Cp/Cpk ≥1.67 data furnished for aerospace and nuclear audits.
• Each lot undergoes residual-stress measurement, salt-spray validation (≥1 000 h), and load–deflection sampling on calibrated servo presses, guaranteeing traceable compliance with DIN 2093 tables.
• Shot-peened surface Ra ≤0.8 µm plus passivation minimise crack initiation; optional electropolish achieves Ra ≤0.4 µm for food, pharmaceutical and semiconductor tools.
• Heat-number & load curve encoded in a QR matrix on packaging link every washer to melt chemistry, hardness, non-destructive test and fatigue report, ensuring full transparency for mission-critical applications.
