Core technical parameters

– Product Model: 805301374
– Product Name: Washer (Special for XCMG Construction Machinery)
– Material specifications: The main body is made of 65Mn spring steel or SUS304 stainless steel (selected as needed). 3Cr13 material can be selected for some scenarios. It is treated with quenching and tempering process to improve hardness and elasticity. The inner diameter of the gasket is 8-50mm, the outer diameter is 16-68mm, and the thickness is 1.2-5.0mm. The surface is treated with electrophoretic coating or chrome plating for corrosion protection.
– Processing technology: Through multiple core processes such as raw material screening and purification, CNC precision stamping, heat treatment strengthening, surface anti-corrosion treatment, dimensional calibration, and flatness testing, the gasket surface is smooth without burrs or scratches, with a dimensional error of ≤0.05mm, excellent flatness, no deformation or cracks, and precise thread fit. No secondary processing is required. Before leaving the factory, it undergoes special testing in multiple dimensions such as hardness, sealing performance, corrosion resistance, and wear resistance, ensuring zero defects in quality.
– Suitable for various XCMG machine models: Fastener connection parts are specifically designed for various XCMG machine models, covering key parts such as engines, gearboxes, pipeline interfaces, and drilling and production mechanisms. They are suitable for harsh working conditions such as high temperature and dust, heavy oil, high frequency vibration, heavy load impact, and alternating high and low temperatures.
– Core parameters: Hardness HRC42-50 (spring steel), HV300-370 (stainless steel), tensile strength ≥780MPa, yield strength ≥650MPa, sealing performance meets IP67 rating, salt spray test ≥900 hours, temperature resistance -40℃~280℃, dimensional error ≤0.05mm, service life ≥10000 hours.
– Temperature range: -40℃~280℃, suitable for all operating conditions of equipment, with excellent creep resistance, thermal shock resistance and corrosion resistance. It does not crack, deform or fail under high and low temperature environments, ensuring stable sealing and anti-loosening performance. It is suitable for use in medium and high temperature parts such as engine periphery.
– Structural features: Adopting a standardized structural design, it fits the original XCMG fastener dimensions, with high flatness and excellent elasticity, which can effectively distribute the pressure of the connecting parts and prevent wear on the connecting surfaces; the surface anti-corrosion treatment can resist the erosion of oil, water vapor and corrosive media; it has good anti-loosening performance and also has a sealing function.
– Installation method: It comes with XCMG original bolts, nuts and other fasteners. It adopts the socket installation method. Before installation, check the specifications, clean the oil and dust on the mounting surface and the surface of the connecting parts, accurately put the washer into the bolt, align the connecting surface, and tighten the nut according to the original torque to ensure tight fit, firm fixation, no looseness, no deviation, easy disassembly and assembly, and convenient for daily maintenance and parts replacement.
– Service life: ≥10,000 hours under normal operating conditions, 1-year warranty, corrosion rate ≤0.0015mm/year, waterproof, oil-proof, dustproof, corrosion-resistant, wear-resistant, no deformation, no cracks, no failure after long-term use, effectively extending the service life of fasteners and connection parts, and reducing equipment maintenance costs.
