TL;DR:
A Hyundai final drive is the travel reduction gearbox that converts hydraulic power into the track movement of your excavator. For models like the Hyundai R210-7, R215-9, R225-9, R250LC-7, and R305LC-7, BN Gears (Hongxiang Machinery) supplies precision-manufactured aftermarket replacements matched to OEM part numbers, with worldwide shipping and a 90-day warranty.
Replacing a worn travel gearbox on a Hyundai excavator is never a decision you make lightly. Downtime costs money. A wrong part costs even more. That's why procurement teams, equipment managers, and independent contractors across Southeast Asia, Europe, and the Americas turn to BN Gears—a manufacturer with over 26 years of experience producing travel reducers and swing reducers for 600+ construction machinery models.
This guide covers everything you need to know: how to identify the right Hyundai final drive for your machine, what makes BN Gears a trusted source, and how to place an order with confidence.
If you have ever wondered what is a final drive, the answer is straightforward. A final drive is the last stage in an excavator's power transmission chain. It takes hydraulic pressure from the travel motor and converts it into mechanical torque, which then drives the sprocket and moves the track. Without a functioning travel gearbox, an excavator cannot move—full stop.
On Hyundai R-series machines, the final drive assembly sits inside each track frame. The travel motor attaches directly to the gearbox, and the gearbox output connects to the sprocket hub. This compact, sealed design means the unit handles enormous loads under muddy, abrasive, and high-impact conditions every single day.
Planetary gear sets are at the core of this system. Multiple stages of reduction—typically two or three, depending on the machine class—allow a relatively small hydraulic motor to generate the massive torque needed to push a 20–30 tonne machine across rough terrain.
BN Gears stocks and manufactures travel reduction gearboxes for a wide range of Hyundai excavator models. The table below lists the most commonly requested units, along with their OEM part numbers and BN stock codes.
Excavator Model | BN Stock Code | OEM Part Number | Sprocket Holes | Frame Holes |
|---|---|---|---|---|
Hyundai R210-7 / R225-7 / R250LC-7 | 9208003 | XKAH-00901 / 610B1101-0100 | 30 | 30 |
Hyundai R210-7 / R215-9 / R225-9 | 9208006 | 31N6-40041 / 31Q6-40020 | 30 | 30 |
Hyundai R250LC-7 / R209LC-7 / R305LC-7 | 9208100 | 31N8-40070 / 31N8-40050 | 26 | 18 |
Each unit ships fully assembled and ready to install. The motor shaft and motor housing are already integrated. No separate motor is included, which keeps costs down when your travel motor is still serviceable.
Hongxiang Machinery Co., Ltd.—the company behind the BN Gears brand—was founded in 2000 and operates from an 18,000 m² facility in Jiangmen, China. The manufacturing operation runs more than 80 advanced production units, supported by a team of 8 senior engineers with over 30 years of combined design and machining experience.
Every travel gearbox that leaves the BN factory goes through a controlled heat treatment process. This step increases the bending strength of planetary gears, prevents case crushing under heavy torque loads, and delivers exceptional wear resistance over a long service life. BN Gears holds ISO 9001:2015 certification, confirming that quality management processes meet internationally recognized standards.
The company currently serves customers in Southeast Asia (65% market share), North and South America (10%), the Middle East (8%), Europe (8%), and Russia (5%). Long-term supply relationships with companies such as Foster Wheeler Power Machinery and C.R. Dinly further demonstrate the reliability of BN's manufacturing output.
For buyers sourcing parts of final drive assemblies—including carriers, sun gears, ring gears, needle bearings, floating seals, and thrust washers—BN Gears maintains an extensive catalog of over 12,000 individual components across its product range.
Getting the right gearbox starts with the part number, not just the machine model. Hyundai has produced multiple variants of models like the R210 and R250 across different production series, and these variants do not always share identical travel gearbox specifications.
Follow these steps to confirm the correct unit before ordering:
Locate the OEM part number on the existing gearbox housing or in the machine's parts manual.
Count the sprocket holes and frame holes on the current unit. For example, the R210-7 uses a 30-hole sprocket hub, while the R305LC-7 uses a 26-hole configuration.
Cross-reference with BN's stock code to confirm availability and lead time.
Contact BN Gears directly via email at info@hx-machinery.cn or WhatsApp at +8613672844386 if you are uncertain. The sales team can verify compatibility before you commit to a purchase.
Stock units typically ship within 4–7 business days. Bulk production orders require 10–35 days depending on quantity. Shipment is available by sea, air, or carrier freight, with trade terms including EXW, FOB, CFR, and CIF.
A failed travel gearbox does not have to mean extended downtime. BN Gears maintains ready stock of the most common Hyundai final drive models, and the team can source or manufacture less common variants to match virtually any Hyundai R-series machine.
All BN replacement units carry a 90-day warranty from the date of arrival. If a quality issue arises, BN will replace the defective part. Plywood case packaging ensures units arrive protected and free from fumigation requirements for international shipping.
To request a quote or confirm part compatibility for your Hyundai R210-7, R215-9, R225-9, R250LC-7, or R305LC-7, contact the BN Gears team today at info@hx-machinery.cn.
The R210-7 uses part number XKAH-00901 (BN stock code 9208003) with a 30-hole sprocket hub, while the R215-9 uses part number 31N6-40041 (BN stock code 9208006), also with 30 sprocket holes. The internal reduction gear assemblies differ between the two series, so confirming the OEM part number before ordering is essential.
No. BN final drive assemblies ship with the motor shaft and motor housing already installed, but the hydraulic travel motor itself is not included. This is standard for replacement gearboxes and keeps costs down when the motor is still in working condition.
In-stock units are processed and packed within 4–7 business days. Bulk or custom production orders take 10–35 days. Delivery is available worldwide by sea freight, air freight, or international carrier.
Yes. BN Gears stocks a wide range of individual gearbox spare parts, including planetary gears, sun gears, ring gears, needle bearings, floating seals, carriers, and thrust washers. These are available for both current and older Hyundai excavator models.
BN provides a 90-day warranty from the date of arrival. Defective units are replaced at no charge. The warranty does not cover incorrect installation, overloading, natural disaster damage, or corrosion caused by improper storage.
