330300087 Casing XCMG XDE130 Electric driving dump truck spare parts

The 330300087 casing addresses the pain points of traditional casings, such as easy wear, deformation, guidance deviation, and weak corrosion resistance. It is widely used in drilling and transmission systems of XCMG construction machinery, especially suitable for complex operating scenarios such as mines and loose strata. It serves as a key structural component for borehole wall protection, power transmission guidance, and load buffering, and is essential for equipment maintenance and original equipment manufacturer (OEM) parts. This product features a corrosion-resistant and wear-resistant coating and is manufactured through multiple processes including precision forging, precision boring and grinding, and high-temperature heat treatment. In terms of performance, it achieves H7 grade dimensional accuracy, is compatible with corresponding XCMG OEM parts, has a tensile strength ≥980MPa, is suitable for environments ranging from -30℃ to 120℃, shows no white rust after 48 hours of salt spray testing, exhibits excellent wear resistance, and can stably perform its guiding and protective functions. It is compatible with multiple series of XCMG construction machinery.

Core technical parameters:

– Product Model: 330300087
– Product Name: Sleeve (Special for XCMG Construction Machinery)
– Material Specifications: XCMG-specific 40Cr high-strength alloy, precision-formed structure, outer diameter 16-63mm (suitable for corresponding specifications), conforming to relevant industry standards, balancing strength and guiding performance.
– Machining process: Precision forging, precision boring and grinding, high-temperature heat treatment, anti-corrosion coating, smooth surface, robust structure, high dimensional accuracy, suitable for complex working conditions.
– Compatible Models: XCMG series construction machinery (including excavators, rotary drilling rigs, cranes, etc., compatibility search available), precisely matching original factory assembly dimensions.
