805238372 Nut XCMG XDE130 Electric driving dump truck spare parts

This product specifically addresses industry pain points such as low thread precision, easy stripping, poor anti-loosening performance, weak corrosion and vibration resistance, and limited applicability of ordinary nuts. It can be customized in thread specifications, dimensions, and materials to balance tightening performance and installation compatibility, making it suitable for various complex operating scenarios. The product uses high-quality alloy raw materials and undergoes precision machining. Its structure closely matches the layout of XCMG’s original equipment manufacturer (XCMG) connectors, ensuring precise threads and seamless compatibility with original bolts and washers. It aligns with XCMG’s supply chain digitalization and standardization management requirements, facilitating convenient installation and maintenance and reducing equipment repair costs.

Core technical parameters

– Product Model: 805238372
– Product Name: Nut (XCMG Construction Machinery Special)
– Material Specifications: The main body is made of 45# carbon steel, 65Mn spring steel or SUS304 stainless steel (selected as needed). For some heavy-duty scenarios, 27MnCrV alloy material can be selected. It is treated with quenching and tempering, carbonitriding and other processes to improve hardness and toughness. The thread specifications are M8-M50 (coarse thread/fine thread can be customized as needed). The nut thickness is 6-30mm. The surface is treated with galvanizing, phosphating or Dacromet anti-corrosion treatment. It is equipped with XCMG original bolts and washers.
– Processing technology: Through multiple core processes such as raw material screening and purification, cold heading, CNC precision turning, thread rolling, heat treatment strengthening, surface anti-corrosion treatment, dimensional calibration, and thread accuracy testing, a three-level precision pressing system is adopted to improve accuracy. There is no stripping or cracking, no need for secondary processing. Before leaving the factory, it undergoes special testing in multiple dimensions such as hardness, anti-loosening performance, corrosion resistance, and thread accuracy, ensuring zero defects in quality.
– Suitable for specific applications: Designed for key connection parts of various XCMG models, including engines, gearboxes, chassis, pipeline interfaces, drilling and production mechanisms, etc., and 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 HRC38-48 (carbon steel/alloy material), HV300-380 (stainless steel material), tensile strength ≥800MPa, yield strength ≥680MPa, anti-loosening torque ≥120N·m, corrosion resistance IP67, salt spray test ≥1000 hours, temperature resistance -40℃~300℃, dimensional error ≤0.04mm, service life ≥12000 hours.
– Temperature range: -40℃~300℃, suitable for all operating conditions of equipment, with excellent creep resistance, thermal shock resistance and corrosion resistance. It does not crack, deform or strip under high and low temperature environments, ensuring stable fastening and anti-loosening performance. It is suitable for use in medium and high temperature parts such as engine periphery.
– Structural Features: Adopting a standardized hexagonal structure design, it conforms to the dimensions of XCMG original fasteners, with high thread precision, tight meshing, and less prone to stripping; some models have built-in nylon inserts or 30° helical tooth rings, which utilize the friction damping effect to achieve efficient anti-loosening and effectively resist the risk of loosening caused by high-frequency vibration; the surface is treated with anti-corrosion to resist the erosion of oil, water vapor, and corrosive media; the wall thickness is uniform, the load-bearing capacity is strong, and it can effectively distribute heavy load pressure, taking into account practicality and adaptability.
– Installation method: It comes with XCMG original bolts and washers and uses threaded fastening. Before installation, check the specifications, clean the threads and mounting surface of oil and dust, align the bolt threads and screw them in accurately, and tighten them according to the torque specified by XCMG to ensure a tight fit, firm fixation, no loosening, no stripping, easy disassembly and assembly, and convenient daily maintenance and parts replacement.
– Service life: ≥12,000 hours under normal operating conditions, 1-year warranty, corrosion rate ≤0.0012mm/year, waterproof, oil-proof, dustproof, corrosion-resistant, wear-resistant, anti-slip, no deformation, no cracks, no failure after long-term use.

We focus on the research and development and production of XCMG components, using high-quality materials and advanced cold heading and heat treatment processes. Using this product can effectively improve the fastening stability of the connectors, reduce loosening, stripping, breakage and other faults, and ensure efficient operation of equipment. Relying on XCMG’s nationwide after-sales network, we provide timely fault response and fully meet the stringent operating requirements of XCMG construction machinery.
