The 802141162 Rubber Bearing (Pin) is a genuine XCMG elastomeric bearing engineered to provide flexible, load‑bearing support for pin joints in articulated dump trucks and heavy construction equipment. This OEM bearing, identified by part number 802141162, features a precision‑machined inner bore designed to accept a straight or slightly tapered pin, with a robust rubber layer bonded between inner and outer steel sleeves. Manufactured from high‑resilience natural rubber compound, the 802141162 rubber bearing absorbs shock, dampens vibration, and accommodates angular misalignment, ensuring reliable pivot performance in the harsh environments of mining, quarrying, and earthmoving.
The 802141162 Rubber Bearing (Pin) is a precision‑engineered elastomeric bushing designed to provide flexible, load‑bearing articulation for pin joints in XCMG articulated dump trucks and heavy equipment.
This genuine OEM bearing features a straight cylindrical bore that accepts a standard pin shaft, with a robust rubber layer bonded between the inner and outer steel sleeves.
The rubber element absorbs shock loads, dampens vibration, and accommodates angular misalignment, protecting the pin and surrounding structure from wear and fatigue.
Its bonded construction ensures that the rubber remains securely attached to the metal sleeves, providing consistent performance over millions of cycles.
A worn or seized bearing can cause binding, excessive play, and accelerated pin wear. The 802141162 bearing eliminates these risks with reliable, long‑lasting performance.
In XCMG articulated dump trucks, rubber bearings are used at numerous pivot points in the suspension, steering, and articulation systems to allow controlled movement while supporting heavy loads.
The 802141162 bearing is typically installed in suspension linkage pivots, steering knuckle mounts, and stabilizer bar attachments, where it enables smooth rotation while damping shock.
Without a properly functioning bearing, metal‑to‑metal contact occurs, leading to rapid wear of pins, bushings, and brackets.
The rubber element also reduces noise transmission and isolates the cab from harsh impacts, improving operator comfort.
The 802141162 bearing is engineered to withstand the extreme loads and repetitive cycling of off‑road haulage, ensuring long‑term reliability.
The 802141162 bearing features a concentric design with a straight inner bore that allows a standard pin to pass through with a controlled clearance or slight interference fit.
The inner and outer steel sleeves are precision‑machined to tight tolerances, ensuring consistent wall thickness and even load distribution across the rubber.
The rubber element is compression‑molded and chemically bonded to both sleeves using a proprietary adhesive system that provides exceptional peel and shear strength.
The rubber compound is formulated with anti‑oxidants and anti‑ozonants to resist environmental degradation, and its 65 Shore A hardness provides an optimal balance between flexibility and load capacity.
The bearing includes lubrication grooves on the inner sleeve to facilitate grease distribution and reduce friction between the pin and the bearing.
The 802141162 bearing uses a high‑grade natural rubber compound that offers excellent tear strength, resilience, and low‑temperature flexibility.
The compound is mixed with carbon black and processing aids to achieve the desired modulus and damping characteristics, while maintaining a high elongation at break.
The bonding process involves grit‑blasting the metal sleeves, applying a primer and adhesive, and then injecting the rubber under heat and pressure in a mold.
This ensures a bond strength exceeding 11 N/mm, preventing separation even under severe dynamic loads.
The result is a bearing that maintains its spring rate and damping properties over millions of articulation cycles.
The 802141162 rubber bearing is widely used in XCMG articulated dump trucks operating in surface mining, underground mining, and heavy construction.
It is commonly installed in suspension linkage pivots, steering knuckle mounts, and stabilizer bar links, where it provides controlled flexibility.
The bearing is also used in articulation joints on some models, allowing the front and rear sections to pivot relative to each other.
Its robust design and sealed construction (with integral dust lips) protect against contamination from mud, water, and abrasive dust.
The 802141162 bearing is also suitable for other XCMG equipment, including wheel loaders and motor graders that share similar pivot geometries.
Every 802141162 bearing is manufactured in an ISO 9001‑certified facility under strict quality control procedures.
Incoming steel tubes and rubber compounds are tested for chemical composition, hardness, and tensile strength before production.
During machining, the inner and outer diameters are verified using precision gauges and coordinate measuring machines.
After bonding, each bearing is inspected for bond integrity using ultrasonic testing and destructive peel tests on sample parts.
Finished bearings are subjected to radial and axial spring rate testing, as well as dynamic durability testing under combined radial and angular loading.
This comprehensive quality assurance programme guarantees that every 802141162 bearing meets XCMG’s exacting standards for reliability and safety.
The 802141162 bearing is designed as a direct replacement for the original bearing on XCMG articulated dump trucks, including models XDA30, XDA40, XDA45, XDA45U, XDA60, TA30, AD45, AD60, and other variants.
Its straight bore diameter (50 mm) and outer diameter (80 mm) match the factory specifications, ensuring proper press‑fit in the housing and correct pin clearance.
The bearing is supplied with a thin film of anti‑corrosion oil; the pin shaft should be cleaned and lightly lubricated before assembly.
For cross‑brand applications, verify that the pin diameter, housing bore, and width are compatible.
Always consult the parts manual to confirm the correct part number for your specific application.
Proper installation of the 802141162 bearing is essential for optimal performance. Begin by thoroughly cleaning the housing bore and the pin shaft to remove debris and corrosion.
Apply a thin layer of anti‑seize or press‑fitting lubricant to the outer sleeve and the housing bore to facilitate insertion.
Using a suitable press and a bearing installation tool, press the bearing into the housing with even force, ensuring it is fully seated against the shoulder.
Insert the pin shaft through the inner sleeve, ensuring it is aligned and not forced, which could damage the rubber element.
If the bearing is equipped with a grease fitting, apply a few pumps of compatible grease (lithium‑based) to lubricate the pin‑to‑sleeve interface.
During routine maintenance, inspect the bearing for signs of cracking, splitting, or excessive play. Check for metal‑to‑metal contact or uneven wear on the pin shaft.
If the bearing shows signs of degradation (e.g., rubber hardening, loss of preload), replace it immediately to prevent further damage to the linkage.
The 802141162 bearing complies with ASTM D2000 and SAE J200, meeting the requirements for oil resistance, heat resistance, and low‑temperature flexibility.
The bearing is free from restricted substances such as lead, cadmium, and PAHs, complying with RoHS and REACH regulations.
Its flame resistance is tested per SAE J369 for use in off‑highway equipment.
Using genuine XCMG bearings like the 802141162 helps maintain compliance with equipment warranty and safety regulations.
Aftermarket rubber bearings often use inferior rubber compounds, poor bond quality, or incorrect dimensions, leading to premature failure and unsafe conditions.
The genuine 802141162 bearing is engineered to the exact specifications of XCMG, ensuring correct fit, consistent spring rate, and long service life.
