Product Introduction

This comprehensive seal kit includes specialized oil seals and gaskets, designed to maintain fluid integrity and protect internal components from dirt, water, and debris in heavy-duty truck systems.

Structure & Material

• Material:

• Main seals: High-temperature resistant nitrile rubber (NBR) for oil compatibility and wear resistance.

• Gaskets: Reinforced rubber with metal inserts (where applicable) for enhanced sealing pressure.

  • Design: A multi-component kit with precision-molded seals (including a 双唇 rotary seal and static gaskets) tailored to fit specific vehicle components (e.g., axle hubs, transmission shafts).

Performance

• Leak Prevention: Creates a tight, durable seal to retain lubricants (oil, grease) in gearboxes, axles, and hubs.

• Contamination Protection: Blocks dirt, water, and road debris from entering critical components, reducing wear.

• Temperature Resistance: Withstands the high operating temperatures of heavy-duty truck systems (up to 120°C).

Durability

• Nitrile rubber construction resists oil degradation, ozone, and aging for long service life.

• Precision molding ensures consistent fit and sealing performance under vibration and pressure.

Core Function

1. Fluid Retention: Prevents lubricant leaks from axles, gearboxes, or hubs.

2. Contamination Block: Shields internal components from external debris.

3. System Integrity: Maintains proper lubrication levels to extend component life.

Key Features and Benefits of Oil Seal 06.56289.0331-0371

Engineered for Longevity

This oil seal is manufactured using high-grade nitrile rubber (NBR) combined with a precision-machined metal casing. Consequently, it resists oil degradation, heat aging, and abrasion far better than generic aftermarket seals. The lip design maintains consistent radial force on the shaft, which means leak-free performance throughout its service life.

Exact OEM Fitment

Dimensionally identical to the original Shacman part number 06.56289.0331-0371, this seal drops right in without modifications. Therefore, your technicians save valuable labor time during installation, and you avoid the costly risk of misfit returns.

Cost-Efficient Procurement

Because we ship directly from our China-based supply hub, there are no middlemen inflating the price. In addition, we offer flexible MOQ arrangements and bulk pricing tiers — ideal for distributors and fleet operators managing large inventories.

Application Scenarios

This Oil Seal 06.56289.0331-0371 Shacman is specifically designed for the following use cases:

• Compatible Vehicles: Shacman heavy-duty truck series (F2000, F3000, X3000, H3000)
• Mounting Position: Trailer hitch seat (towing coupling) at the rear chassis
• Service Occasions: New chassis assembly, scheduled preventive maintenance, seal damage replacement, and post-accident repair

In other words, whenever the rear towing interface shows signs of oil seepage or the seal has reached its service interval, this part is the go-to solution.

Frequently Asked Questions – Oil Seal 06.56289.0331-0371 Shacman

What causes an oil seal at the trailer hitch seat to fail prematurely?

Several factors accelerate wear on this particular seal. Excessive shaft runout, contaminated lubricant, and prolonged exposure to temperatures beyond the rated range all shorten its lifespan. Additionally, improper installation — such as cocking the seal during press-fit — can damage the sealing lip before the truck even leaves the workshop.

How can I verify that 06.56289.0331-0371 fits my specific Shacman model?

First, cross-reference the part number stamped on your existing seal or listed in the vehicle’s parts catalog. This number — 06.56289.0331-0371 — is a Shacman OEM reference, so it corresponds directly to the factory specification. If you’re still unsure, send us your VIN or chassis number and we’ll confirm compatibility.

Is this oil seal made from the same material as the original Shacman part?

Yes. Our Oil Seal 06.56289.0331-0371 uses NBR (nitrile butadiene rubber) bonded to a carbon-steel shell — identical to the OE specification. This ensures equivalent chemical resistance and mechanical performance under real-world operating conditions.

What is the recommended replacement interval for this seal?

Generally, oil seals in the rear chassis towing assembly should be inspected every 100,000–150,000 km or during each major service. However, if you notice oil weeping around the trailer hitch seat or detect play in the coupling, replace the seal immediately regardless of mileage.

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

Absolutely. We understand that procurement managers need to validate quality before scaling up orders. Mettlead offers flexible MOQ arrangements — even sample orders — so you can test fitment and durability with minimal financial risk.
