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

The 330101066 U-bolt assembly is a standard original equipment manufacturer (OEM) fastening accessory for construction machinery. Specifically designed for connecting and fixing equipment pipelines, steel structures, and components, it is compatible with corresponding machine models and solves problems such as bolt loosening, corrosion, and breakage. Widely used in cranes, crawler chassis, and pipeline fixing, it is a key component for maintenance and installation. This product complies with the JB/ZQ4321-1997 industry standard and OEM standards, using 40Cr high-strength carbon steel, manufactured through precision cold heading, tempering heat treatment, and hot-dip galvanizing for corrosion protection. It comes with double nuts and flat washers, offering strong adaptability and resistance to complex working conditions. Its strong fastening properties prevent loosening and breakage, and it is temperature resistant from -40 to 100℃. Corrosion-resistant and wear-resistant, it can precisely fix components, reducing failures and maintenance costs, and extending equipment life.
