Introducing our state-of-the-art anti-loosening washers, engineered for unparalleled stability and security in diverse applications across industries.
Ingenious Working Principle
Friction-Based Anti-Loosening: Our washers, such as spring washers, harness the power of elastic deformation. When a nut is tightened, the washer compresses, exerting pressure on the nut, enhancing friction between the nut and bolt, effectively preventing loosening.
Mechanical Locking Anti-Loosening: Emulating the robust design of a toothed washer, these washers interlock with the surface of the connected part through their tooth tips, preventing the nut from rotating relative to the bolt, ensuring steadfast anti-loosening performance.
• Tension Anti-Loosening: Our double-layered self-locking washers capitalize on the tension between two washers and the meshing of inclined tooth surfaces. When loosening occurs, only the inner inclined tooth surfaces move, generating lifting tension to return the nut to its original position.
Versatile Types
Elastic Washers: Crafted from durable rubber or plastic, these washers boast excellent wear and shock resistance. Available as flat or convex washers, they are ideal for high-friction and vibration-prone equipment.
Waveform Washers: Featuring a unique serrated design, these washers cushion between fasteners and workpieces, crafted from stainless steel or copper, they are indispensable in chemical, aerospace, and other advanced fields.
Disc-Shaped Elastic Washers: Also known as DIN6796, these conically structured washers endure axial loads, storing energy and rebounding to release potential energy, preventing loosening in medium to high-strength bolt connections.
SK Anti-Loosening Washers: Ingeniously blending toothed patterns with disc spring geometry, these washers compensate for tension loss due to vibration, boosting friction and mitigating dynamic load impacts.
VSK Anti-Loosening Washers: These saddle-shaped washers, featuring a non-slip hemp surface, are tailored to prevent thread loosening from axial loads. The VSKZ variant is optimized for cylindrical head screw installations.
• SCHNORR® Safety Washers: These advanced conical ring double-sided ratchet washers, based on disc spring principles, prevent friction damage, offer superior vibration resistance, and ensure optimal load distribution with high pre-tightening force.
Diverse Application Areas
Automotive Manufacturing: Essential for securing connections between engine, transmission, and suspension components, these washers guarantee automobile safety and performance.
Aerospace: Critical for maintaining the reliability of aircraft engines, wings, and other key components, ensuring fasteners remain secure even in extreme environments.
Industrial Machinery: Crucial for equipment like pumps, fans, and compressors, our anti-loosening washers enhance operational stability and safety.
Architecture: In construction, these washers are vital for fastening steel bars and bolts, ensuring the structural integrity and safety of buildings.
