330101066 U-bolt assembly XCMG XDE130 Electric driving dump truck spare parts

The 330101066 U-bolt assembly is an original equipment manufacturer (OEM) product from XCMG, specifically designed for XCMG excavators (such as the XE200GH), loaders (such as the XC968-EV), mining machinery, and fully mechanized mining equipment. It addresses the shortcomings of ordinary U-bolts, such as easy loosening, poor corrosion resistance, insufficient load-bearing capacity, and misalignment of the inner flange. It is a core component for equipment fastening and maintenance. The product uses high-quality base materials and is manufactured through CNC machining, precision bending, thread tapping, and surface galvanizing/Dacromet coating/anti-corrosion passivation treatment. It is suitable for high-temperature, high-dust, high-frequency vibration, and salt spray corrosion conditions, perfectly matching OEM equipment and aligning with XCMG’s supply chain digitalization requirements.

Core technical parameters

– Product Model: 330101066
– Product Name: U-bolt Assembly (for XCMG construction machinery)
– Material specifications: High-quality carbon steel (Q235, 45# steel) / 304 stainless steel / S33010 heat-resistant stainless steel (12Cr16Ni35, chromium content 14.00%~17.00%, nickel content 33.00%~37.00%), thread specifications M6-M48, suitable pipe diameter 25-114mm, matching nuts, flat washers, spring washers, the inner arc of the gasket fits tightly with the suitable pipe diameter, and meets relevant standards and XCMG matching requirements.
– Machining process: CNC turning, precision bending (die control of curvature), thread tapping, surface galvanizing/Dacromet/anti-corrosion passivation treatment, thread accuracy 6g, no burrs, no diameter reduction, tested for hardness and tensile strength, stable operation, excellent vibration resistance and anti-loosening effect.
– Suitable for: XCMG excavators, loaders, mining machinery, fully mechanized mining equipment, etc., used to fix components such as pipes, frames, leaf springs, scraper conveyor chains, etc., suitable for high temperature and high dust, high frequency vibration, salt spray corrosion, and oily conditions, and suitable for complex fastening scenarios of fully mechanized mining and engineering machinery.
– Core parameters: Tensile strength ≥372.5MPa (carbon steel), ≥515MPa (S33010 material), thread tolerance 6g, load capacity ≥15kN, salt spray test ≥72 hours, installation error ≤0.3mm, surface zinc coating thickness ≥8μm.
– Temperature range: -40℃~600℃ (S33010 material), -40℃~120℃ (carbon steel/304 stainless steel), suitable for outdoor and complex equipment working conditions, anti-creep and anti-aging, oil and corrosion resistant, no brittleness at low temperature, no deformation at high temperature, and can withstand long-term vibration and impact.
– Structural features: U-shaped integrated structure, bending arc fits tightly with the appropriate pipe diameter, full and firm thread, matching spring washer and flat washer to enhance the anti-loosening effect, surface anti-corrosion treatment for rust and corrosion resistance, compact size, smooth and burr-free edges, fits the equipment layout.
– Installation method: Matches XCMG original interface, threaded fastening + spring washer and flat washer to prevent loosening. Before installation, the threads and mounting surface must be cleaned. The tightening torque meets XCMG standards. No equipment modification is required. Disassembly and assembly are convenient. It can be used with shock-absorbing components to improve the vibration resistance effect.
– Service life: ≥8000 hours under normal working conditions, 2-year warranty, corrosion rate ≤0.002mm/year. The service life of S33010 material is 30% longer than that of ordinary stainless steel. It is waterproof, oil-proof and dustproof, without deformation, stripping or breakage, and has stable fastening performance over a long period of time.

We specialize in XCMG components. Our 330101066 U-bolt assembly is manufactured according to XCMG’s original factory processes, using molds to control the bending arc, ensuring precise dimensions and a complete set of components. It undergoes rigorous quality inspection and hardness and tensile strength testing, achieving a pass rate of ≥99.5%, making it a perfect replacement for original factory parts. Using this product improves component stability, prevents loosening and detachment, reduces component wear, lowers maintenance costs, and is compatible with various XCMG construction machinery and mining equipment.
