Product Description: A heavy-duty, cast-iron hub with a corrosion-resistant black oxide coating. It features precision-machined mounting holes for secure attachment to the engine and shock absorber, and its robust construction withstands high vibration and impact loads.

Function: Serves as the mounting interface between the engine’s shock absorber and the vehicle frame. It dampens engine vibrations and isolates them from the chassis, reducing noise and improving ride comfort while protecting other components from excessive stress.

Shock Absorber Hub 200V02602-0127 for SINOTRUK – Factory-Direct OEM Quality

When your SINOTRUK fleet demands uncompromising vibration control and engine longevity, the Shock Absorber Hub 200V02602-0127 delivers exactly that. Engineered to meet original equipment specifications, this critical damping component absorbs torsional vibrations generated by the crankshaft, protecting your powertrain from premature fatigue and costly downtime. METTLEAD Truck Parts brings this genuine-spec part directly from our quality-controlled production line in China to your warehouse — no middlemen, no inflated margins.

Key Functions and Buyer Benefits

Precision Vibration Damping

The Shock Absorber Hub 200V02602-0127 sits at the front end of the crankshaft assembly, neutralizing harmful torsional oscillations before they propagate through the engine block. This preserves bearing life, reduces gear train noise, and extends overall powertrain service intervals.

OEM-Grade Material Integrity

Manufactured from high-carbon steel with a vulcanized rubber elastomer ring, this hub maintains its damping coefficient across a wide temperature range (−40°C to +120°C). It resists heat aging, oil contamination, and ozone cracking — the three silent killers of inferior aftermarket dampers.

Direct Cost Savings for Procurement Teams

• Factory-direct pricing — eliminates distributor markups by 20–35%
• Batch order flexibility — MOQ as low as 5 pieces for trial orders
• Reduced fleet downtime — precise dimensional tolerances ensure first-time-right installation
• White-label packaging available — supports your private brand strategy

Strict Quality Control You Can Verify

Every Shock Absorber Hub 200V02602-0127 undergoes dynamic balancing testing, dimensional inspection (CMM verified), and rubber hardness validation before shipment. We welcome procurement managers to visit our facility for on-site quality audits.

Technical Specifications

Application Scenarios — Where This Part Works Hardest

The Shock Absorber Hub 200V02602-0127 is purpose-built for the following SINOTRUK vehicle platforms:

• SINOTRUK SITRAK C7H — Long-haul logistics tractors operating 200,000+ km/year on intercity highways
• SINOTRUK HOWO T7H — Heavy-duty 6×4 dump trucks enduring high-RPM cycles in mining and construction zones
• SINOTRUK HOWO A7 — Port container haulers subjected to constant stop-start torsional stress

In each scenario, the crankshaft damper hub absorbs resonant vibrations that peak between 1,200–1,800 RPM — the exact operating band where MC11/MC13 engines spend most of their working life. Without a properly functioning damper hub, crankshaft fatigue cracks can develop within 150,000 km, leading to catastrophic engine failure.

Fleet operators across Africa, Southeast Asia, the Middle East, and Central Asia trust this part to keep their SINOTRUK vehicles running profitably in extreme heat, dust, and high-altitude conditions.

Frequently Asked Questions — Shock Absorber Hub 200V02602-0127

What is the exact function of the Shock Absorber Hub 200V02602-0127 in the engine?

This hub serves as the structural mounting core of the crankshaft torsional vibration damper. It bolts directly to the crankshaft nose and carries the inertia ring via a bonded rubber element. Together, they counteract torsional resonance that would otherwise fatigue the crankshaft and damage front-end accessories like the alternator and water pump.

How do I confirm this part fits my specific SINOTRUK model?

Cross-reference OEM number 200V02602-0127 against your vehicle’s engine nameplate (MC11 or MC13 series). If you are unsure, send us your VIN or engine serial number through our contact page and our technical team will verify compatibility within 2 hours during business days.

What are the signs that this damper hub needs replacement?

Watch for visible rubber cracking or separation between the hub and inertia ring, unusual front-end engine vibration at idle, wobbling of the accessory belt, or harmonic noise increasing with RPM. Industry best practice recommends inspection every 200,000 km and replacement no later than 400,000 km.

Is this part identical in quality to the original SINOTRUK factory part?

Yes. We manufacture to the same dimensional tolerances, material grades, and dynamic balance standards as the OE specification. Every unit passes the same G6.3 balance grade and rubber durometer hardness test that the original part requires.

Can I order a small trial quantity before committing to bulk?

Absolutely. Our minimum order for the Shock Absorber Hub 200V02602-0127 is 5 pieces — enough for your quality validation and fitment testing before scaling up.
