803591167 Flat Washer XCMG XDE130 Electric driving dump truck spare parts

The 803591167 flat washer effectively solves common problems such as fastener deformation under pressure, wear and tear on assembly contact surfaces, loose screws and gaps, leakage and loosening caused by uneven stress, washer aging and thinning, corrosion failure, pressure breakage, and poor assembly fit. It is suitable for replacing old flat washers in construction machinery, inspecting equipment fastening points, upgrading assembly protection systems, OEM assembly for new machines, and upgrading the overall machine structure for fastening and maintenance. The product is made of original high-strength alloy steel, precision stamped, finely ground and calibrated, and surface-treated with rust and corrosion prevention and hardening processes. The surface is flat and uniform, with precise thickness, excellent pressure resistance, and is not easily deformed under stress. It has moderate hardness, is wear-resistant and pressure-resistant, and the surface is rust-proof, corrosion-resistant, anti-aging, and fatigue-resistant. It can adapt to the harsh operating conditions of construction machinery, including high-frequency vibration, heavy load, outdoor dust and oil contamination, and alternating humidity and temperature differences. It effectively distributes bolt tightening pressure, prevents damage to equipment contact surfaces, and improves overall assembly tightness and structural stability.

Core technical parameters:

– Product Model: 803591167
-Product Name: Flat Washer
– Material specifications: Original high-strength alloy steel, hardened and rust-proofed, with strong pressure resistance, wear resistance and deformation resistance, and not easy to rust or break.
– Processing technology: precision one-piece stamping, flatness calibration, surface anti-corrosion reinforcement, and multiple quality inspections for pressure resistance, flatness, and durability.
– Performance and working condition adaptability: Distributes pressure, protects contact surfaces, resists vibration and loosening, and is suitable for heavy-duty vibration fastening conditions of engineering machinery.
– Structural features: Standard original specifications, precise dimensions, high fit, easy assembly and disassembly, eliminating the risk of pressure deformation and assembly damage.

This product undergoes specialized testing at the factory, including pressure resistance, flatness verification, rust prevention and weather resistance, and vibration durability, meeting the original equipment manufacturer (OEM) and standard fastener assembly standards for construction machinery. Replacing the fastener with this product effectively protects the equipment’s assembly contact surfaces, evenly distributes fastening pressure, and prevents structural damage, loose screws, and abnormal assembly gaps. It enhances the overall structural stability, extends the service life of fasteners and equipment assembly points, reduces maintenance costs caused by structural loosening, and continuously ensures the tight, safe, and long-term stable operation of various connection structures in construction machinery.
