As fundamental non‑engine mechanical components, these steel balls ensure accurate load distribution, reduce wear, and extend the service life of bearings and rotating systems.
In heavy‑duty mining and construction equipment, every rolling element must perform with absolute consistency. These balls are manufactured to Grade G10, which guarantees a sphericity deviation of less than 0.25 µm and a surface finish of Ra ≤ 0.02 µm, ensuring that they roll with minimal friction and generate negligible heat.
The tight dimensional tolerance of +4(-0.2) µm ensures that the balls fit precisely within the bearing raceways, providing uniform load distribution across all rolling elements and preventing premature fatigue of the rings.
Manufactured from high‑grade chrome steel with a controlled hardness of 60–66 HRC, these steel balls offer exceptional resistance to wear, impact, and plastic deformation, making them suitable for the most demanding applications.
This component set is a direct OEM replacement, restoring original rotational performance after wear or damage, ensuring that the vehicle maintains its driveline efficiency and machine uptime.
The 800546813 Steel Balls are the core rolling elements in ball bearings used throughout XCMG articulated dump trucks – from wheel hubs and transmission shafts to steering knuckles and hydraulic pump bearings.
By providing a near‑perfect spherical contact surface, these balls reduce friction to a minimum, allowing shafts to rotate freely while supporting radial and axial loads effectively.
A bearing with high‑quality steel balls exhibits lower operating temperatures, reduced noise, and longer grease life, all of which contribute to extended maintenance intervals and lower operating costs.
The precise geometry and surface finish also help to maintain proper preload and clearance in the bearing assembly, preventing skidding and smearing that can lead to premature failure.
By using genuine XCMG 800546813 steel balls, technicians can be confident that the rolling elements will match the original performance specifications, ensuring that the bearing operates as designed.
The 800546813 Steel Balls feature a meticulously controlled manufacturing process that ensures consistency in diameter, sphericity, and surface integrity.
The balls are produced from vacuum‑degassed chrome steel, which reduces non‑metallic inclusions and improves fatigue life. After cold‑heading, they undergo a multi‑stage grinding and lapping process that achieves the required dimensional accuracy and surface finish.
The final diameter tolerance of +4(-0.2) µm is measured using high‑precision optical comparators and laser micrometers, ensuring that each ball falls within the specified range.
The surface finish is polished to a mirror‑like quality, reducing friction and allowing for smoother rotation. This also improves the load‑carrying capacity by increasing the contact area under load.
A corrosion‑resistant oil film is applied to each ball to protect against rust during storage and handling, ensuring that they arrive in pristine condition.
The balls are supplied in convenient quantities, and each batch is accompanied by a certificate of conformance that includes actual measured values for diameter, roundness, and hardness.
The 800546813 Steel Balls are manufactured from GCr15 (SAE 52100) chrome steel, a material specifically chosen for its excellent hardenability, wear resistance, and fatigue strength.
The steel is subjected to a thorough heat treatment process that includes martempering and tempering to achieve a uniform hardness of 60–66 HRC across the entire volume of the ball.
This hardness level provides the necessary resistance to indentation and plastic deformation under high contact stresses, while the tempered structure maintains sufficient toughness to withstand impact loads.
The stabilisation treatment also ensures that the balls retain their dimensional stability even when exposed to elevated temperatures during operation, preventing changes in bearing internal clearance.
The combination of premium material and precise heat treatment results in steel balls that deliver consistent performance over an extended service life, reducing the frequency of bearing replacements and minimising downtime.
The 800546813 Steel Balls are produced in ISO 9001 and ISO 14001 certified facilities, adhering to the highest quality and environmental standards.
The raw steel is sourced from approved mills and undergoes rigorous incoming inspection, including chemical composition analysis, non‑metallic inclusion rating, and grain size evaluation.
The cold‑heading process is performed on high‑speed presses with precise die control, ensuring consistent ball diameter and minimal ovality.
The grinding and lapping stages are carried out on advanced CNC machines with in‑process gauging that continuously monitors size and roundness, rejecting any out‑of‑tolerance parts.
Each ball is 100% inspected for diameter, sphericity, and surface defects using automated optical sorting systems. Hardness testing is performed on sample batches to confirm conformance.
The oil film is applied in a controlled environment, and the balls are packaged in anti‑rust materials to ensure they remain in perfect condition until installation.
These rigorous quality assurance measures guarantee that every 800546813 steel ball delivers the reliability, performance, and durability expected from a genuine XCMG component.
The 800546813 Steel Balls are a critical factor in the overall reliability and safety of XCMG articulated dump trucks.
A bearing that contains sub‑standard or mismatched steel balls can suffer from uneven load distribution, leading to premature wear, spalling, or even catastrophic seizure.

Handling and installing the 800546813 Steel Balls requires care to preserve their precision surfaces and avoid contamination.
Before installation, clean the bearing housing, the races, and the balls to remove any dirt, dust, or old grease. Use a lint‑free cloth and a suitable solvent.
Inspect each ball for visible defects such as scratches, pits, or corrosion. If any ball is damaged, discard it and use a new one.
Apply a thin, even coat of high‑quality bearing grease to the raceways and the balls before assembling the bearing. This ensures that the balls are properly lubricated from the start.
When assembling the bearing, place the balls evenly around the circumference, ensuring that the ball cage (if used) is correctly positioned. Avoid forcing the balls, as this can damage the raceways.
After assembly, rotate the bearing by hand to check for smooth movement and any signs of binding or roughness. If any abnormality is found, disassemble and inspect again.
During routine maintenance, inspect the bearing for signs of wear, pitting, or discolouration. Replace the balls if any damage is visible, and always use genuine parts to ensure consistent quality.
