The 803304747 Cage Seal 100×130×12 is a genuine XCMG heavy‑duty hub seal engineered to provide reliable oil containment and contamination exclusion in the wheel hub final drives and axle assemblies of articulated dump trucks and heavy mining equipment.
This OEM cage seal, identified by part number 803304747, features a precision‑molded nitrile rubber sealing lip with a metal casing, delivering exceptional resistance to gear oil, heat, and abrasive contaminants.
With dimensions of 100 mm inner diameter, 130 mm outer diameter, and 12 mm thickness[reference:0], the 803304747 cage seal ensures a precise fit in the hub bore, preventing costly lubricant leaks and protecting bearings from premature wear.
Designed for the extreme pressures, temperature fluctuations, and mechanical stresses of mining and construction, this seal is the ideal replacement for worn or damaged hub seals on XCMG articulated dump trucks.
The 803304747 Cage Seal 100×130×12 is a precision‑engineered sealing component designed to prevent lubricant leakage and contaminant ingress in the wheel hub and axle assemblies of XCMG articulated dump trucks.
This genuine OEM cage seal is a critical component for maintaining oil containment in final drives, ensuring that gear oil stays within the hub and that abrasive particles such as dust, mud, and water are kept out.
Manufactured from high‑grade nitrile rubber bonded to a precision‑formed steel casing, the seal offers excellent resistance to gear oil, heat, and mechanical stress, delivering reliable performance over thousands of operating hours.
The 803304747 seal is designed to fit shaft diameters of 100 mm and housing bores of 130 mm, with a width of 12 mm[reference:4], ensuring a precise fit and optimal sealing pressure.
A failed hub seal can lead to costly oil leaks, bearing failure, and unplanned downtime. The 803304747 cage seal eliminates these risks with rugged, long‑lasting construction.
In XCMG articulated dump trucks, cage seals – also known as cassette seals – are the primary barrier that keeps gear oil contained within the wheel hub final drive and prevents contamination from entering the bearing assembly[reference:5].
The 803304747 seal is typically installed at the outboard end of the hub, where it seals the rotating shaft against the stationary housing, maintaining oil pressure and protecting the bearings from abrasive wear.
Without a properly functioning cage seal, gear oil escapes from the hub, leading to inadequate lubrication, overheating, and catastrophic bearing failure.
The robust metal casing of the 803304747 seal provides structural integrity and prevents distortion during installation, while the nitrile sealing lip maintains constant contact with the rotating shaft, ensuring a leak‑tight seal.
Regular inspection and timely replacement of the hub seal with a genuine XCMG part like the 803304747 is essential for maximising axle life and minimising maintenance costs.
The 803304747 cage seal features a precision‑molded nitrile rubber sealing lip that is engineered to provide consistent contact pressure against the rotating shaft, ensuring effective sealing even under high‑speed operation.
The lip geometry includes a hydrodynamic pumping feature that actively returns any oil that may have migrated past the primary lip back into the hub, reducing the risk of leakage.
The steel casing is precision‑stamped and zinc‑plated for corrosion resistance, providing a rigid foundation that ensures the seal remains securely seated in the housing bore.
The seal’s 100 mm inner diameter and 130 mm outer diameter are precisely matched to XCMG hub dimensions, guaranteeing a correct interference fit[reference:6].
A protective dust lip on the outer face of the seal helps to exclude large contaminants, further extending the service life of the primary sealing lip.
The 803304747 cage seal is manufactured from a high‑performance nitrile rubber (NBR) compound that offers outstanding resistance to gear oils, greases, and moderate heat.
The nitrile material maintains its elasticity and sealing force across a wide temperature range, from -40°C to +100°C, ensuring reliable performance in both arctic and tropical climates.
The compound is formulated with anti‑oxidants and anti‑ozonants to resist environmental degradation, extending the seal’s service life even in harsh outdoor conditions.
The rubber is compression‑molded to ensure a smooth, defect‑free sealing surface that minimises friction and wear on the rotating shaft.
This advanced material science ensures that the 803304747 cage seal delivers consistent, reliable performance over thousands of operating hours.
The 803304747 cage seal is used extensively in XCMG articulated dump trucks and other heavy equipment operating in surface mining, underground mining, and large‑scale construction.
It is the primary hub seal for the wheel final drive assemblies, protecting the bearings and planetary gears from contamination and lubricant loss.
The seal is also used in axle assemblies, differential housings, and other rotating shaft applications where a reliable oil seal is required.
Its robust construction and precise dimensions make it suitable for use in dusty, wet, and high‑vibration environments common in mining and quarrying operations.
The 803304747 seal is also compatible with other XCMG equipment, including wheel loaders and excavators that use the same hub seal dimensions.
Every 803304747 cage seal is manufactured in an ISO 9001‑certified facility under strict quality control procedures.
Incoming nitrile compounds and steel materials are tested for chemical composition, hardness, and dimensional accuracy before production.
During molding and assembly, each seal is inspected for lip integrity, casing dimensions, and bond strength between the rubber and metal.
Finished seals are subjected to 100% dimensional inspection and leak testing to verify sealing performance at operating pressures.
Random samples from each batch are tested for compression set, tensile strength, and oil resistance to ensure compliance with ASTM D2000 standards.
This comprehensive quality assurance programme guarantees that every 803304747 seal meets XCMG’s exacting standards for reliability and safety.
The 803304747 cage seal is designed as a direct replacement for the original hub seal on XCMG articulated dump trucks, including models XDA30, XDA40, XDA45, XDA45U, XDA60, TA30, AD45, AD60, and other variants.
Its 100 mm inner diameter and 130 mm outer diameter match the factory shaft and housing specifications, ensuring a precise, interference fit[reference:7].
The 12 mm width is compatible with standard hub bore depths, allowing for correct seating and optimal sealing pressure[reference:8].
For cross‑brand applications, verify that the shaft diameter, housing bore, and width are compatible with your specific hub assembly.
Always consult the parts manual to confirm the correct seal for your machine.
Proper installation of the 803304747 cage seal is essential for optimal sealing performance. Begin by thoroughly cleaning the hub bore and the shaft to remove any debris, old sealant, or corrosion.
Inspect the shaft for burrs, scoring, or wear that could damage the sealing lip. Polish the shaft if necessary to achieve a surface finish of 0.2‑0.6 μm Ra.
Apply a thin film of clean gear oil or assembly lubricant to the sealing lip and the housing bore to reduce friction during installation.
Using a suitable seal installation tool, press the seal evenly into the housing bore, ensuring it is fully seated against the shoulder and not cocked.
Avoid using excessive force, which can deform the casing or damage the sealing lip. Do not reuse a seal that has been dropped or damaged.
During routine maintenance, inspect the hub for signs of oil leakage or contamination. Replace the seal immediately if leakage is observed.
Regularly check gear oil levels and quality, as degraded oil can accelerate seal wear and lead to premature failure.
The 803304747 cage seal complies with ASTM D2000 (classification system for rubber materials) and SAE J200, meeting the requirements for oil resistance, heat resistance, and low‑temperature flexibility.
It is manufactured in accordance with ISO 9001 quality management standards, ensuring consistent product quality and traceability.
The materials used are free from restricted substances and comply with RoHS and REACH environmental regulations.
Using genuine XCMG seals like the 803304747 helps maintain compliance with equipment safety and warranty requirements.
