OEM 860553208 The XCMG Tapered Roller Bearing (860553208) is a genuine OEM precision rolling element bearing engineered to support combined radial and axial loads in the wheel‑end, axle, and driveline assemblies of XCMG articulated dump trucks. This high‑capacity tapered roller bearing, identified by part number 860553208, is a critical component for ensuring smooth rotational motion, accurate shaft alignment, and long‑term reliability under the extreme shock loads, heavy payloads, and continuous duty cycles encountered in mining, quarrying, and construction operations.
Manufactured from high‑grade vacuum‑degassed chrome steel with precision‑ground rolling elements, hardened raceways, and a durable anti‑corrosion coating, the 860553208 tapered roller bearing delivers exceptional load‑carrying capacity, fatigue resistance, and dimensional stability under severe operating conditions. Its precision‑engineered geometry and cage design guarantee a perfect fit and optimal performance without modification.
The 860553208 tapered roller bearing features a separable cone and cup design for easy assembly, precision‑ground rollers and raceways for smooth, quiet operation, and a corrosion‑resistant finish, making it an indispensable component for maintaining driveline efficiency, reducing friction, and maximising uptime in your ADT fleet.
The 860553208 Tapered Roller Bearing is manufactured from premium vacuum‑degassed SAE 52100 chrome steel with precision grinding and heat treatment, ensuring consistent dimensional accuracy and structural integrity across every unit.
Its tapered roller geometry allows the bearing to accommodate both high radial loads and significant axial (thrust) loads in either direction, making it ideal for wheel‑end and differential applications.
The precision‑ground rollers and raceways provide a large contact area, distributing loads evenly and reducing stress concentrations, which extends bearing life and reduces wear.
The separable cone and cup design facilitate easy assembly, inspection, and adjustment, simplifying maintenance and reducing downtime.
The anti‑corrosion coating provides robust protection against moisture, salts, and chemicals, ensuring reliable operation in harsh mining and construction environments.
In demanding applications such as wheel ends, final drives, and differential assemblies, the 860553208 delivers reliable, long‑lasting performance for your ADT’s driveline.
Articulated dump trucks rely on tapered roller bearings to support rotating shafts and gears within the transmission, differential, and wheel‑end assemblies, enabling smooth power delivery and minimising friction losses.
The 860553208 tapered roller bearing ensures that shafts and gears rotate with minimal resistance, reducing wear on mating surfaces and improving overall driveline efficiency.
A worn or damaged bearing can cause increased friction, heat generation, and premature failure of gears and shafts, leading to costly downtime and repairs.
Field data shows that ADTs equipped with genuine XCMG tapered roller bearings experience 45% fewer driveline failures compared to those using aftermarket or rebuilt bearings.
The bearing’s precision‑ground rollers and optimised geometry ensure smooth, quiet operation and consistent performance throughout its service life.
Regular inspection of tapered roller bearings is recommended; any signs of pitting, spalling, or excessive wear should be addressed by immediate replacement.
The 860553208 is produced using advanced centreless grinding and superfinishing processes, achieving roller and raceway surface finishes of ≤0.05 μm Ra for optimal rolling efficiency and reduced friction.
The vacuum‑degassed SAE 52100 chrome steel provides a clean, homogeneous microstructure with excellent fatigue resistance and dimensional stability under heavy loads.
The cage is precision‑stamped from high‑strength steel with manganese phosphate coating, providing accurate roller spacing and preventing skew or misalignment.
The rollers are precision‑ground to tight diameter tolerances (±0.002 mm), ensuring even load distribution and minimising stress concentrations.
All edges are deburred and radiused to reduce stress concentrations and to facilitate safe handling during installation.
Every unit undergoes 100% dimensional inspection, hardness testing, and magnetic particle inspection to guarantee interchangeability with OEM specifications.
The 860553208 features a case‑hardened rolling surface (60‑64 HRC) that provides outstanding wear resistance and resistance to pitting and spalling under heavy loads.
The tough, ductile core (30‑35 HRC) provides excellent shock resistance, preventing roller and raceway fracture under impact loads.
The bearing is coated with an anti‑corrosion oil or phosphate treatment, providing excellent corrosion protection in harsh environments.
The combination of a hard, wear‑resistant surface and a tough core ensures the bearing can withstand heavy loads and shock impacts without premature failure.
All materials are RoHS compliant and free from hazardous substances, meeting stringent environmental standards.
The superior wear and corrosion resistance makes this bearing ideal for the most demanding off‑highway applications.
The 860553208 is designed for professional installation using standard workshop tools, requiring careful handling to avoid damage to the precision‑ground rolling elements and raceways.
To install, first clean the housing bore and shaft thoroughly, and inspect for any burrs or foreign material before assembly.
Apply a thin layer of clean oil to the bearing surfaces and carefully press the bearing into the housing using an appropriate press tool, ensuring it is fully seated.
After installation, verify that the shaft rotates freely without binding, and that the bearing is correctly aligned with the mating components.
During routine maintenance, inspect the bearing for signs of wear, scoring, or corrosion, and replace if any damage is observed.
Always use genuine XCMG tapered roller bearings to ensure correct fit, material quality, and performance.
