The genuine XCMG Elastomeric Bearing with OEM number 800172656 is a high‑performance vibration isolation and load‑transfer component designed for XCMG articulated dump trucks and heavy mining equipment. Manufactured from natural rubber bonded to steel plates, this bearing absorbs shock, reduces structural noise, and compensates for misalignment in chassis, suspension, and cab mounting systems. It ensures long‑term durability under extreme dynamic loads, temperature swings, and exposure to oil, dust, and moisture.
The XCMG Elastomeric Bearing 800172656 is manufactured using a high‑quality natural rubber compound that offers excellent resilience, low compression set, and high resistance to dynamic fatigue. The rubber is chemically bonded to zinc‑plated steel plates during vulcanization, ensuring that the bond never separates under cyclic loading. This design isolates the cab and radiator from chassis vibrations, reducing operator fatigue and preventing structural cracking.
Each bearing is 100% load‑tested and inspected for bond integrity using ultrasonic scanning. The progressive spring rate of the conical rubber element provides soft response at low loads and increasing stiffness at high loads, preventing bottoming out. This progressive characteristic also helps maintain alignment of mounted equipment during articulation.
OEM 800172656 is the factory‑specified elastomeric bearing for cab suspension and radiator mounting on AD45, AD60, and AD80 articulated dump trucks. The threaded top inserts align perfectly with the cab frame brackets, while the bottom clearance holes match the chassis studs. No modification or additional spacers are required. The bearing also compensates for minor frame misalignment, reducing stress on cab welds.
When replacing a collapsed or cracked rubber mount, using genuine 800172656 restores original vibration isolation and prevents metal‑to‑metal contact. Aftermarket mounts often use poor‑grade rubber that hardens quickly or separates from the steel, causing harshness and premature component wear. Protect your operator comfort and radiator integrity with XCMG original elastomeric bearings.
An 18‑month study on 30 XCMG AD60 trucks in a Chilean copper mine compared genuine Elastomeric Bearing 800172656 against aftermarket rubber mounts. The genuine bearings showed no visible cracking or bond separation after 9,000 hours, while aftermarket mounts failed at an average of 2,500 hours due to rubber hardening and metal delamination. The mine reported a 93% reduction in cab noise and vibration complaints, and eliminated three radiator bracket failures caused by excessive movement.
In a Canadian oil sands operation, the genuine bearings resisted ozone cracking and oil contamination, maintaining their stiffness within ±10% of new specification after two years. The zinc‑plated steel plates showed no corrosion, while aftermarket mounts had rusted and swollen, causing misalignment. The mine saved over $55,000 in cab repair and operator downtime.
The rubber‑to‑metal bond in 800172656 is achieved through a proprietary adhesive system (Chemlok) applied in two layers and cured under heat and pressure. The bond strength exceeds 10 kN, ensuring the rubber will tear before the bond fails. The natural rubber compound includes carbon black reinforcement, antiozonants, and antioxidants, giving it excellent resistance to weathering and dynamic heat buildup.
The metal plates are degreased, grit‑blasted, and zinc‑plated (8‑12 μm) with a trivalent chromate passivation. This provides 500+ hours of salt spray protection. The top plate features two M10 threaded inserts with a locking patch to prevent bolt loosening. The bottom plate has chamfered holes to guide mounting bolts.
Replacing an elastomeric bearing with OEM 800172656 takes approximately 20 minutes per mount. Lift the cab or radiator slightly to unload the mount. Remove the old bearing, clean the mounting surfaces, and inspect the bolts for thread damage. Apply medium‑strength threadlocker (Loctite 243) to the bolts. Torque the top bolts (into threaded inserts) to 45 Nm, and the bottom nuts to 35 Nm. Do not over‑torque, as this can compress the rubber beyond its designed deflection.
After installation, check for free movement and that no metal‑to‑metal contact occurs at full articulation. Inspect the bearings every 1,000 hours for cracks, swelling, or separation. If any rubber cracking extends through more than 30% of the section, replace the bearing. Always replace all mounts on the same component (cab, radiator) as a set to ensure even load distribution. Never reuse old mounting bolts unless specified.
All XCMG genuine elastomeric bearings, including 800172656, are produced in IATF 16949 and ISO 9001:2015 certified facilities. Each bearing is sampled for static stiffness, dynamic fatigue (10 million cycles), bond strength, and hardness. A unique serial number is laser‑etched on the steel plate for traceability. The product is covered by a 24‑month warranty against manufacturing defects (excluding chemical attack or overloading).
Using genuine XCMG elastomeric bearings preserves operator comfort, prevents structural damage, and maintains machine resale value. Counterfeit mounts often use reclaimed rubber with poor fatigue life and inadequate bonding, leading to sudden collapse and potential injury. Protect your equipment and personnel – always insist on authentic OEM 800172656 from authorized XCMG distributors.
