As a non‑engine mechanical accessory, this heavy‑duty sleeve ensures proper spacing between mating parts, preventing metal‑to‑metal contact, reducing friction, and distributing clamping forces evenly across bolted joints.
In the harsh operating conditions typical of mining, quarrying, and heavy construction, bolted joints and pivot points are subjected to constant vibration, impact loading, and thermal expansion.
The 332106402 spacer sleeve is engineered to maintain precise dimensional stability, ensuring that fasteners remain properly torqued and that adjacent components are correctly positioned throughout the vehicle’s operating life.
Manufactured from high‑strength carbon steel with a fully corrosion‑resistant zinc‑nickel plating and a durable black powder‑coat finish, this spacer sleeve delivers exceptional compressive strength, wear resistance, and long‑term durability.
This component is a direct OEM replacement, restoring the original clearance and alignment specifications, ensuring that all interconnected systems function as intended.
The 332106402 Spacer Sleeve is a critical element in maintaining the structural integrity and alignment of bolted connections on XCMG articulated dump trucks.
Properly spaced joints prevent bending and shear stresses on bolts, ensuring that clamp loads are evenly distributed and that the joint remains secure under dynamic loads.
Without accurate spacing, fasteners can become loose or overstressed, leading to premature fatigue failure, component misalignment, and increased wear on adjacent parts.
This sleeve ensures that critical assemblies – such as suspension mounts, steering linkages, and driveline supports – maintain their designed geometry, reducing the risk of downtime and costly repairs.
The 332106402 Spacer Sleeve features a carefully engineered design that combines precise dimensional control, high load capacity, and ease of installation.
The sleeve is precision‑turned from seamless carbon steel tubing, ensuring a smooth, concentric bore and outer surface that provides consistent contact with mating components.
An outer diameter of 40 mm and an inner diameter of 25 mm accommodate standard M24 bolts and provide ample bearing area for load distribution.
The 50 mm overall length is manufactured to tight tolerances (±0.1 mm), ensuring accurate spacing and consistent clamping force across the joint.
Both ends of the sleeve are squared and deburred to provide a flat, parallel bearing surface that prevents uneven loading and minimizes the risk of bolt bending.
The sleeve’s robust wall thickness of 7.5 mm provides excellent resistance to crushing and deformation, even under high torque and impact loads.
The 332106402 Spacer Sleeve is produced using advanced CNC machining and quality control processes, ensuring consistent dimensional accuracy and mechanical properties.
The raw material – seamless Q345B steel tubing – is sourced from approved mills and undergoes rigorous inspection for chemical composition and mechanical properties.
CNC turning operations are performed on high‑precision lathes, with regular tooling checks and in‑process measurements to maintain tight tolerances on diameter, length, and concentricity.
Each sleeve is inspected for dimensional accuracy using coordinate measuring machines (CMM) and verified against the engineering drawings to ensure a perfect fit.
The result is a spacer sleeve that delivers consistent, reliable performance, with a service life that matches or exceeds that of the original equipment.
The 332106402 Spacer Sleeve is protected by a dual‑layer coating system that ensures exceptional corrosion resistance and a professional appearance.
The base layer is a zinc‑nickel electroplating that provides sacrificial cathodic protection and offers over 500 hours of salt spray resistance (ASTM B117), significantly outperforming standard zinc plating.
The top coat is a black powder coating that is baked on to form a tough, abrasion‑resistant finish. This coating provides excellent resistance to stone chipping, UV degradation, and chemical exposure.
The combination of these coatings ensures that the spacer sleeve retains its protective properties and appearance even after years of service in aggressive mining and construction environments.
The black finish also blends seamlessly with the vehicle’s chassis and other components, maintaining a professional and uniform appearance across the entire machine.
The 332106402 Spacer Sleeve is manufactured from premium Q345B (equivalent to S355J2) carbon steel, a material renowned for its excellent strength, weldability, and toughness.
Q345B offers a minimum yield strength of 345 MPa, providing the structural integrity required to withstand the compressive forces and vibration loads encountered during vehicle operation.
The steel’s low carbon equivalent ensures good formability and machinability, making it suitable for the precision turning processes used in the sleeve’s manufacture.
Each sleeve 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, manganese, silicon, and other alloying elements.
Dimensional accuracy is verified using precision measurement tools, with critical outer diameter, inner diameter, length, and concentricity checked against the engineering drawings to ensure a perfect fit.
The result is a spacer sleeve that delivers consistent, reliable performance, with a service life that matches or exceeds that of the original equipment.
The 332106402 Spacer Sleeve plays a vital role in preventing joint failure, misalignment, and premature wear on XCMG articulated dump trucks.
Incorrect spacing can cause bolts to be subjected to excessive bending moments, leading to fatigue fracture and sudden separation of critical components – a serious safety hazard.
Similarly, uneven load distribution can cause localized deformation of bolted flanges, resulting in loss of clamp force and joint loosening over time.
The 332106402 sleeve prevents these issues by providing a rigid, dimensionally stable spacer that maintains correct clearances and ensures that clamp loads are evenly distributed across the joint.
Regular inspection of spacer sleeves is recommended during routine maintenance to check for signs of deformation, corrosion, or wear. Any damaged sleeves should be replaced promptly.
Using a genuine XCMG 332106402 spacer sleeve ensures that the component meets the original design specifications, providing the intended level of strength and durability.

Installing the 332106402 Spacer Sleeve is a quick and straightforward process that can be completed with basic hand tools, minimizing downtime and maintenance effort.
Before installation, clean the sleeve and the mating surfaces to remove any dirt, grease, or debris that could affect the joint’s clamping force.
Position the sleeve between the two components to be joined, ensuring that it is correctly aligned with the bolt holes and that the bearing surfaces are parallel.
Insert the bolt through the assembly, then thread the nut onto the bolt. Hand‑tighten the nut until the joint components are in contact with the sleeve.
Using a torque wrench, tighten the nut to the manufacturer’s recommended torque specification, following a diagonal pattern if multiple bolts are used to ensure even clamp load.
During routine maintenance, inspect the spacer sleeve for signs of deformation, corrosion, or wear. Check the torque of the fasteners and re‑tighten if necessary.
