The six bolt holes are precisely positioned on a 110 mm pitch circle diameter, with counterbored seats that accommodate M12 bolts and provide even clamping pressure across the flange face.
A keyway is machined into the bore to accept a standard key, providing a positive mechanical connection that prevents rotation and ensures that the flange remains locked to the shaft even under extreme torque.
The flange’s design also includes a chamfered edge and a smooth radius transition at the bore entry, facilitating easy assembly and preventing damage to seals or O-rings during installation.
The 332106324 Locking Flange undergoes a carefully controlled case-hardening process that provides a wear-resistant surface while maintaining a tough, ductile core.
The case-hardening process involves carburizing the surface to a depth of 1.0–1.5 mm, followed by quenching and tempering to achieve a surface hardness of 58–62 HRC and a core hardness of 30–35 HRC.
This combination of hard surface and tough core provides excellent resistance to wear, galling, and plastic deformation, while preventing brittle fracture under impact loads.
The flange is then finished with a zinc-nickel plating that provides exceptional corrosion resistance, followed by a black phosphate coating that enhances lubricant retention and provides a low-friction surface for mating components.
The zinc-nickel plating offers over 500 hours of salt spray resistance, ensuring the flange remains free from rust and corrosion even when exposed to moisture, mud, and aggressive chemicals.
The black phosphate coating also reduces the risk of galling between the flange and the mating surface during assembly and disassembly, extending the service life of both components.
The 332106324 Locking Flange is manufactured from premium 41Cr4 alloy steel (equivalent to AISI 5140), a material specifically selected for its excellent hardenability, high tensile strength, and good fatigue resistance.
41Cr4 offers a minimum tensile strength of 850 MPa and a yield strength of 650 MPa after heat treatment, providing the strength required for demanding fastening applications.
The material’s chromium content provides good hardenability, allowing for deep, uniform case hardening, while the carbon content ensures the required surface hardness for wear resistance.
Each flange is produced in ISO 9001 and ISO 14001 certified facilities, with strict process controls at every stage – from raw material verification to final inspection.
The chemical composition is verified using spectrometer analysis, ensuring it meets the specified requirements for carbon, chromium, and other alloying elements.
Non-destructive testing (NDT) methods, including magnetic particle inspection (MPI), are used to detect any surface cracks or inclusions that could compromise the flange’s integrity.
The result is a locking flange that delivers consistent, reliable performance, with a service life that matches or exceeds that of the original equipment.
The 332106324 Locking Flange is a critical component for ensuring the long-term reliability and safety of XCMG articulated dump trucks.
The driveline is the backbone of the vehicle’s propulsion system, and any failure in the fastening of shafts, bearings, or couplings can lead to catastrophic breakdowns, costly downtime, and potential safety hazards.
Conventional fasteners, such as standard bolts and washers, can loosen over time due to vibration and thermal cycling, leading to misalignment, excessive wear, and eventual failure of driveline components.
The 332106324 locking flange addresses this issue by providing a positive, multi-layered locking mechanism that combines clamping force, serrated friction, and a keyway to prevent any relative movement between the flange and the shaft.
