Protect Your Final Drive from Catastrophic Failure with a Precision Floating Seal

Guard the heart of your excavator’s undercarriage power with the genuine 2445R442F1 Floating Seal. This critical component, also known as a Duo-Cone seal, is the primary defense for the final drive on your Kobelco SK200-6 and SK230-6 models. A failed floating seal allows gear oil to leak out and abrasive contaminants to enter, leading to rapid wear, bearing failure, and an extremely costly final drive rebuild or replacement. Ensure long-lasting undercarriage performance and avoid devastating downtime with this essential, OEM-spec sealing solution.

Product Overview

The 2445R442F1 Floating Seal is a heavy-duty, mechanical face seal installed in the final drive assembly where the rotating sprocket shaft meets the stationary housing. It consists of two precisely matched, hard-metal sealing rings that float against each other, creating a dynamic barrier. Its dual mission is crucial: to retain thick gear oil inside the final drive and to exclude dirt, mud, and water from the sensitive gear and bearing compartment. Our replacement seal is manufactured to exact original dimensions and hardness specifications, ensuring a perfect seal that can withstand the high pressure, shock loads, and harsh environmental conditions of excavation work.

Key Features & Benefits

• Precision OEM Fit & Performance: Engineered as a direct replacement for part number 2445R442F1, guaranteeing perfect compatibility and sealing integrity for the final drives on Kobelco SK200-6 and SK230-6 excavators.

• Ultimate Final Drive Protection: Forms a robust, dynamic barrier that reliably contains gear lubricant and aggressively excludes all external contaminants, which are the leading cause of final drive failure.

• Durable, Hardened Construction: Made from high-grade alloy steel with a hardened, precision-lapped sealing face. This ensures exceptional wear resistance and a long service life under continuous rotation and high load.

• Prevents Costly Chain Reaction Failures: A single leaking seal can lead to oil loss, contamination ingress, bearing seizure, and gear damage—resulting in a repair bill that is many times the cost of proactive seal replacement.

• Designed for Harsh Environments: The robust duo-cone design is uniquely suited to withstand the extreme conditions of dirt, mud, water, and impact shocks that undercarriage components endure daily.

• Essential for Track Motor & Final Drive Service: This seal is a mandatory replacement item during any final drive disassembly, sprocket replacement, or track motor rebuild to ensure future reliability.

Frequently Asked Questions (FAQ)

Q1: What are the symptoms of a failed 2445R442F1 floating seal?
A: The most obvious sign is gear oil leaking from the inner hub of the final drive, near the sprocket. You may also see contamination (dirt/mud) inside the final drive if the seal is disassembled, or eventually hear grinding noises from the final drive due to bearing failure.

Q2: Is this a single part or a set?
A: The 2445R442F1 Floating Seal is typically sold as a complete set, which includes the two matched metal sealing rings and the necessary rubber O-rings or elastomeric bands that provide the sealing force.

Q3: Can I replace this seal myself, or do I need to remove the final drive?
A: Replacing a final drive floating seal is a major repair. It requires removing the track chain, the final drive assembly from the machine, and fully disassembling the final drive to access the seal. This job demands significant mechanical expertise, special tools (e.g., for bearing removal), and a clean working environment. It is strictly a task for experienced mechanics.

Q4: Why should I replace both floating seals when servicing one final drive?
A: Seals wear at similar rates. If one has failed, the other is likely near the end of its service life. Replacing both inner and outer seals (if applicable) during a single repair ensures maximum longevity and prevents a return visit for the same issue.

Q5: Is this a genuine Kobelco part?
A: This is a high-quality, OEM-compatible replacement seal manufactured to the exact specifications of the original 2445R442F1 part, providing the same critical protection for your machine’s final drive.
