DIN25201 Carbon Steel Double Deck Wedge Самоблокировка стиральной машины Описание

  1. Shock-Proof, Self-Locking Performance
    • Twin discs machined to DIN 25201 incorporate opposed 30 ° wedge cams whose ramp angle exceeds standard thread pitch; any loosening impulse is instantly converted into additional clamp load, stopping back-off during vibration up to 22 g RMS.
    • Radial serrations on the outer faces embed into joint materials at surface pressures as low as 80 MPa, eliminating the need for spring washers, chemical thread-lockers, or deformation of the bolt threads.
    • Core of medium-carbon steel is through-hardened to HRC 45–52 (≈ 350–500 HV) for long-term wear resistance; a ≥ 8 µm zinc layer with trivalent chromate resists 120 h neutral-salt-spray, while optional clear, yellow, black, olive, or custom RAL/Pantone top-coats push corrosion life past 1 000 h and enable quick visual coding.
    • Proven by Junker transverse-vibration testing (DIN 65151) to retain ≥ 90 % of initial preload after 1 000 cycles, even when reused multiple times.
  2. Межотраслевой спектр Применение
    • Transportation & Mobility: Locks suspension brackets, braking shields, and battery enclosures in passenger cars, rail stock, motorcycles, and light electric vehicles that endure shock, heat, and road debris.
    • Heavy Equipment & Renewable Energy: Secures blade-root studs, hydraulic manifolds, and structural joints on wind turbines, solar trackers, cranes, and earth-moving machinery where service access is costly.
    • Automation & Precision Machinery: Maintains positional accuracy on rotary tables, linear guides, and robotic end-effectors during high-cycle operation and sudden axis reversals.
    • Marine, Offshore & Chemical Systems: Duplex-coated variants guard pumps, valves, and deck hardware exposed to chloride-rich atmospheres or mild acids while allowing non-permanent disassembly.
  3. Установщик-дружественный, экономящий время
    • Supplied as pre-assembled pairs with the cam directions matched—simply place under the bolt head or nut; recommended torque remains identical to a plain-washer joint, so existing tool settings can stay unchanged.
    • Stamped directional arrow on the outer face plus tactile serrations provide positive orientation feedback when gloves, oil, or low light impair visibility.
    • Adds only 2 mm to clamp stack height on M6–M20 sizes, enabling retrofit without longer fasteners or design changes in tight recesses.
    • Available loose in cartons, mounted on captive sleeves, or in tape-and-reel strips for seamless use at field sites, manual benches, or automated feeders.
  4. Verified Quality & Traceability
    • 100 % optical inspection measures cam rise ± 0.02 mm, concentricity ≤ 0.05 mm TIR, and outer-rib depth ≥ 0.20 mm; statistical Cp/Cpk data archived for ISO 9001, IATF 16949, and AS9100 audits.
    • Case-hardening depth (0.1–0.3 mm) and surface hardness validated per ISO 16228 to ensure consistent locking behaviour for repeated re-torque cycles.
    • Materials comply with RoHS 3 and REACH; full PPAP Level 3 documentation, 3.1 material certificates, and Junker test curves supplied on request.
    • QR-coded packaging links every washer set to its melt lot, plating batch, and inspection record, guaranteeing end-to-end transparency for safety-critical infrastructure, aerospace tooling, and medical-device assemblies.
