805046640 Bolt XCMG XDE130 Electric driving dump truck spare parts

The 805046640 bolt addresses the pain points of traditional bolts, such as easy breakage, stripping, poor fatigue resistance, and insufficient corrosion resistance. It is widely used in core connection parts of XCMG construction machinery, including frames, slewing bearings, and engines. It is particularly suitable for heavy-duty, high-vibration, and complex operating environments such as mining and infrastructure construction, undertaking the functions of component fastening and power transmission. It is a key fastening component for equipment maintenance and original equipment manufacturer (OEM) parts. This product uses a special 40Cr high-strength alloy, with a Dacromet anti-corrosion treatment. It is manufactured through multiple processes including cold forging, hot forging, precision thread rolling, and high-temperature heat treatment, effectively preventing bolt breakage and loosening, ensuring stable connections of equipment components, avoiding downtime losses due to bolt failure, and extending equipment lifespan.

Core technical parameters:

– Product Model: 805046640
– Product Name: Bolts (Special for XCMG Construction Machinery)
– Material Specifications: XCMG-specific 40Cr high-strength alloy steel, precision rolled thread structure, specifications M16-M24 (suitable for corresponding parts), conforming to GB/T 3098.1-2010 standard, balancing strength and connection performance.
– Machining process: cold heading and hot forging, precision thread rolling, high-temperature heat treatment, Dacromet anti-corrosion coating, resulting in smooth threads, robust structure, no cracks or burrs, suitable for heavy-duty applications.
– Compatible Models: XCMG series construction machinery (including excavators, rotary drilling rigs, cranes, etc., compatibility search available), precisely matching original factory assembly dimensions.
