803591176 Flat Washer XCMG XDE130 Electric driving dump truck spare parts

The 803591176 flat washer can effectively solve common problems such as wear and tear on assembly contact surfaces due to pressure, uneven bolt tightening pressure, indentation damage on contact surfaces, excessive assembly gaps, vibration and abnormal noise at assembly points, rust and thinning of washers, failure due to pressure deformation, and poor structural fit. It is suitable for replacing old flat washers in engineering machinery, inspecting equipment fastening points, upgrading structural protection systems, assembling new machines with original equipment, and maintaining and upgrading the fastening structure of the whole machine. The product is made of original high-strength alloy steel, and is refined through precision one-piece stamping, flat surface grinding calibration, and surface hardening and rust prevention passivation process. The plate surface is flat and regular, the thickness is standard, the pressure bearing strength is high, the stress is uniform and not easily deformed, the hardness and wear resistance are excellent, and it is resistant to extrusion and impact. The surface is rust-proof, corrosion-resistant, aging-resistant and fatigue-resistant. It can be adapted to the harsh working conditions of heavy load bearing, high frequency vibration, outdoor temperature difference, dust, oil and moisture corrosion of engineering machinery. It effectively distributes the bolt tightening pressure, makes up for the assembly gap, protects the contact surface of the equipment from damage, and strengthens the foundation of the whole machine.
