The 801974413 Rubber Bearing (Pin Shaft) is a genuine XCMG elastomeric bushing designed to provide flexible, load‑bearing support in articulated dump truck suspension and articulation joints. This OEM rubber bearing, identified by part number 801974413, is engineered to absorb shock, dampen vibration, and accommodate angular misalignment between pin shafts and mounting brackets. Manufactured from a high‑resilience natural rubber compound bonded to inner and outer steel sleeves, the 801974413 rubber bearing delivers superior durability, low maintenance, and consistent performance in the harshest mining and construction environments.
The 801974413 Rubber Bearing (Pin Shaft) is a precision‑engineered elastomeric bushing that provides flexible, maintenance‑free articulation in XCMG articulated dump trucks.
This genuine OEM component is designed to absorb radial and axial loads while accommodating angular misalignment between the pin shaft and the mounting bracket.
Its bonded rubber‑to‑metal construction ensures a strong, durable bond that resists separation even under extreme cyclic loading.
The bearing’s natural rubber compound offers excellent resilience and low hysteresis, providing effective vibration isolation and shock absorption.
A failed or worn rubber bearing can lead to metal‑to‑metal contact, excessive play, and accelerated wear of pin shafts and brackets. The 801974413 bearing eliminates these risks with consistent, long‑lasting performance.
In XCMG articulated dump trucks, rubber bearings are used at pivot points in the suspension linkage, articulation joint, and steering knuckle to provide controlled flexibility.
The 801974413 bearing is typically installed between the pin shaft and the axle bracket or frame mount, allowing rotational movement while maintaining radial alignment.
Without a properly functioning bearing, the suspension becomes rigid, leading to harsh ride, increased stress on adjacent components, and premature fatigue failure.
The bearing’s rubber element absorbs impact loads from rough terrain, protecting the chassis and drivetrain from shock damage.
Its ability to accommodate misalignment also ensures that the pin shaft remains correctly aligned, preventing binding and uneven wear.
The 801974413 rubber bearing features a concentric design with a precision‑machined inner sleeve that fits snugly over the pin shaft, and an outer sleeve that presses into the mounting bracket.
The rubber element is compression‑molded and chemically bonded to both metal sleeves using a proprietary adhesive system that ensures exceptional bond strength.
The rubber compound is formulated with anti‑oxidants and anti‑ozonants to resist environmental degradation, and its hardness (65 Shore A) provides an optimal balance between flexibility and load‑bearing capacity.
The inner sleeve is zinc‑plated for corrosion resistance, while the outer sleeve is phosphate‑coated to enhance the bond with the rubber.
The bearing’s geometry includes relief grooves and chamfers that facilitate grease flow and prevent stress concentration at the edges.
The 801974413 bearing uses a specially developed natural rubber compound that offers superior tear strength, resilience, and low‑temperature flexibility.
The compound is mixed with carbon black and process oils to achieve the desired hardness and damping characteristics, while maintaining excellent elongation at break.
The bonding process involves surface preparation of the metal sleeves (grit‑blasting and solvent cleaning), application of a proprietary primer, and injection molding of the rubber under heat and pressure.
This ensures that the rubber‑to‑metal bond exceeds 10 N/mm peel strength, preventing separation even under severe dynamic loading.
The result is a bearing that delivers consistent performance over millions of cycles, with minimal change in spring rate or damping.
The 801974413 rubber bearing is extensively used in XCMG articulated dump trucks operating in surface mining, underground mining, and heavy construction.
It is commonly found in the rear suspension linkage, where it allows the axle to articulate relative to the frame, and in the steering knuckle mounts, where it provides a flexible pivot.
The bearing is also used in stabilizer bar links and in some brake reaction rod applications.
Its robust construction and sealed design (with integral dust lips) protect against contamination from mud, water, and abrasive dust.
The 801974413 bearing is also suitable for other XCMG equipment, including wheel loaders and motor graders that share similar suspension architectures.
Every 801974413 rubber bearing is manufactured in an ISO 9001‑certified facility with strict quality control at every stage.
Incoming raw materials (steel tubes, rubber compound) are tested for chemical composition, hardness, and tensile strength.
During production, the bond integrity is verified using ultrasonic inspection and destructive peel tests on sample parts.
Finished bearings undergo 100% dimensional inspection and are subjected to radial and axial spring rate testing on calibrated hydraulic presses.
Dynamic durability tests are performed on representative samples, subjecting the bearing to 5 million cycles of combined radial and angular loading.
This comprehensive quality assurance programme guarantees that every 801974413 bearing meets XCMG’s exacting standards for reliability and safety.
The 801974413 rubber 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 dimensions (50 mm ID × 80 mm OD × 60 mm width) match the factory specifications, ensuring proper press‑fit in the housing and correct pin shaft clearance.
The bearing is supplied with a thin film of anti‑corrosion oil; no additional lubrication is required for installation.
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 801974413 rubber bearing is critical 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 801974413 rubber bearing complies with ASTM D2000 (classification system for rubber materials) 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 polycyclic aromatic hydrocarbons (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 801974413 helps maintain compliance with equipment warranty and safety regulations.
