Présentation du produit
This AZ9725520683 rubber bearing assembly is a coreload-bearing buffer component for the rear suspensionof heavy-duty heavy-duty vehicles, and is also commonlyreferred to as a steel plate buffer rubber seat or
suspension shock absorber pier. Developed specificallyfor dump trucks, dump trucks, and heavy-duty
engineering vehicles, it adopts a 10-layer stacked
high-elastic natural rubber combined with an integratedcast steel base structure. It addresses common issuessuch as unusual frame noise, body movement, and hardwear of steel plates during heavy-duty driving. It
effectively enhances overall vehicle driving stability,
extends the service life of chassis girders and leafsprings, and is the preferred component for replacingwear parts of heavy truck chassis
Applicable Vehicle Models
Accurately compatible with all heavy-duty truck and heavy-duty chassis models, versatile on both sides.
Two pieces per vehicle:
1. Auto HOWO dump trucks, dump trucks, and mining engineering projects
Car
2. HOwOT7H Heavy-duty Transport Model
3. Shandeka C7H premium heavy-duty chassis model
4. Universal number changeable: WW9722520278, size reference
Constant numbers, lossless direct replacement
[Core Features Advantages]
I. Ultra-strong load-bearing and compressive resistance:The thickened cast steel base has strong load capacity,can withstand heavy freight, high-intensity loads onconstruction sites, is less prone to deformation and
collapse, and is suitable for heavy engineering conditions.
2. Efficient vibration and noise reduction:Multi-layer layered rubber buffer structure,
quasi-absorbing road vibrations, rigid friction
between steel and the frame, completely solvingthe chassis abnormal nojse issues during heavyload jogging and rotational braking
3. Durable and wear-resistant: It adopts a
nigh-temperature integrated vulcanization process,
ensuring the rubber layer does not degrease, does not
separate, does not crack, is tear-resistant,
aging-resistant, and corrosion-resistant, suitable forcomplex construction sites and harsh road conditions
during long-distance transportation.
4. Non-destructive adaptation for original vehicles:
Original factory hole positioning, no need for modification
or grinding, simple installation and alignment,
replacement of damaged parts of the original vehicle,
high fitting, and strong stability.
Material and Craft Details
Base material: High-strength cast steel, double-layeranti-corrosion treatment on the surface (primer + topcoat70um/ powder coating 100um can be usedSelected), rust and corrosion prevention, and completelyprevents rust and loosening.
Buffer material: High-purity natural wear-resistantrubber, balanced elastic toughness, and resistance tofatigue deformation under long-term heavy pressure.
· Overall process: One-piece molding and
vulcanization molding, compact structure, stable
layered cushioning effect, significantly exceeding theservice life of a conventional single-layer rubber base.
Common Faults and Replacement Recommendations
Fault Diagnosis (Replace promptly if any of the
following situations occur)
1. The vehicle experiences severe abnormal noisewhen operating under heavy loads or on bumpyroad sections;
2. The vehicle body sways during driving,
deteriorates stability, and swaying when turning;
3. The rubber layer of the support cracks,
degumming, collapses, and hardens due to aging;4. The wear of steel plates and frames increasessignificantly, and the chassis vibration increasessignificantly. Professional Change Tips
