805238802 Nut XCMG XDE130 Electric driving dump truck spare parts

The 805238802 nut  is a dedicated left-hand thread fastener for XCMG construction machinery. Specifically designed for reverse locking scenarios in heavy-duty equipment, it is suitable for core connection parts of XCMG electric dump trucks, loaders, and other equipment. It solves the problems of traditional right-hand thread nuts, such as easy loosening and thread stripping under reverse force, making it a key component for stable equipment operation. This product is made of 35CrMoA high-strength alloy material, manufactured through forging, tempering heat treatment, precision left-hand thread machining, and corrosion protection processes. It is suitable for complex heavy-duty working conditions in mining, infrastructure, and other applications. In terms of performance, it boasts tensile and fatigue resistance, precise left-hand locking, and strong adaptability to high and low temperatures. It reduces loosening failures, lowers maintenance costs, extends equipment life, and eliminates downtime and safety hazards caused by loose nuts, especially suitable for the locking requirements of reverse-forced parts in XCMG equipment.

Core technical parameters:

– Product Model: 805238802
– Product Name: Nut
– Material Specifications: Made of 35CrMoA high-strength alloy material, containing reinforcing elements such as Cr and Mo. After tempering and heat treatment, the hardness is stable in the range of HV250-300. It is compatible with M16 left-hand threads, and the size fits XCMG original equipment. It can withstand high-strength tensile and shear forces and is suitable for heavy-duty reverse force scenarios.
– Processing technology: Hot forging, CNC precision turning, tempering heat treatment, left-hand thread precision turning, surface blackening for corrosion protection, precision testing and other processes are adopted. The threads are smooth and burr-free, the dimensions are accurate, the sharp corners of the hexagonal parts are blunted, the locking fit is tight and flawless, and the reverse locking stability is guaranteed.
– Suitable for various XCMG construction machinery, heavy-duty scenarios such as open-pit coal mines and infrastructure construction sites, adaptable to harsh environments such as vibration, high and low temperatures, and high dust, used for locking and fixing equipment parts subjected to reverse force and high-speed rotating parts, and suitable for core connection parts of XCMG electric dump trucks, loaders and other equipment.
– Specifications: M16 left-hand thread, 2mm pitch, 16mm major diameter and 13.835-14.210mm inner diameter of internal thread, 24mm length of hexagon across sides and 14.8mm thickness. The dimensions are precisely matched to XCMG original equipment and can directly replace original parts without additional adjustments.
– Performance parameters: Strength grade close to 12, excellent fatigue resistance, stable performance at -30℃~80℃, strong corrosion resistance, left-hand thread for secure locking, not easy to loosen under reverse force, and can withstand continuous load without plastic deformation.
– Structural features: Adopts a standard hexagonal structure, which is easy to install and compatible with conventional wrench operation; the left-hand thread provides precise engagement and excellent reverse locking to prevent loosening; it is integrally forged, with no weak points, balancing hardness and toughness to avoid brittle fracture, and the hexagonal part is marked with a left-hand thread for easy identification.
– Durability and cost: Service life under normal working conditions ≥10,000 hours, equipment uptime ≥98%; maintenance cost is reduced by 50% compared to ordinary left-hand nuts, significantly saving replacement costs and downtime losses caused by loose nuts; compatible with bolts of the same material for use as a set, improving the stability of the locking system.
