803591181 Standard Spring Washer XCMG XDE130 Electric driving dump truck spare parts

The 803591181 standard spring washer effectively solves problems caused by high-frequency vibration in equipment, such as fastener loosening, thread clearance movement, assembly noise, locking failure, and component wobbling and misalignment. The product is compatible with XCMG excavators, cranes, aerial work platforms, loaders, and other engineering machinery. It is widely used in fastening points such as frame connections, chassis assembly, electrical cabinets, hydraulic components, and protective structures. Relying on its own elastic tension, it continuously presses against the contact surface, offsetting clearance changes caused by equipment vibration, locking the thread tightening force, preventing fasteners from rotating and loosening, and significantly improving the reliability of equipment assembly. This product is made of high-elasticity spring steel, hardened by quenching and tempering, elastically strengthened, and treated with rust and corrosion prevention. It has passed comprehensive tests for elasticity durability, fatigue resistance, compressive deformation resistance, and vibration anti-loosening, possessing advantages such as long-lasting elasticity, strong anti-loosening performance, resistance to fatigue failure, and wear and corrosion resistance.
