Drive Wheel / Final Drive Sprocket for SANY SY1250H & SY1350H

Engineered for Durability and Direct Fit | Manufactured by DPW Machinery Parts

• Compatible Models: SANY SY1250, SANY SY1350 Hydraulic Excavators

• Direct OEM Interchangeable

• Forged Construction | Hardened Tooth Profile

Product Overview

The Drive Wheel (Final Drive Sprocket) is a mission-critical component on your SANY SY1250 and SY1350 excavators, responsible for transferring immense torque from the final drive to the track chain. Its failure can lead to catastrophic downtime and costly damage to the entire undercarriage system.

This DPW Machinery Parts Drive Wheel Assembly is meticulously engineered as a direct replacement for the original SANY component. By utilizing advanced forging techniques and precise heat treatment, we deliver a product that matches or exceeds OEM specifications for strength and wear resistance, ensuring maximum uptime in construction, quarrying, and heavy-duty earthmoving applications.

Key Features & Engineering Advantages

• High-Strength Forged Steel Core

  • Feature: Fabricated from premium carbon alloy steel using a closed-die forging process that refines the metallic grain structure.

  • Benefit: Provides exceptional tensile strength and impact toughness, significantly reducing the risk of tooth breakage or core cracking under high-stress conditions compared to cast alternatives.

• Precision Hardened Tooth Flanks

  • Feature: Sprocket teeth are treated with controlled induction hardening to achieve a deep, uniform surface hardness (typically 55-58 HRC).

  • Benefit: Dramatically increases resistance to abrasive wear caused by contact with the track chain bushings, extending the service life and preventing premature "hook" formation on the teeth.

• CNC-Machined for Guaranteed Fitment

  • Feature: All critical interfaces—including the spline bore, mounting flange, and bolt holes—are machined on CNC equipment to exact OEM tolerances.

  • Benefit: Ensures a perfect, direct bolt-on replacement without modification. Guarantees precise alignment with the final drive output shaft, ensuring smooth power transmission and eliminating premature wear.

• Corrosion-Resistant Phosphate Coating

  • Feature: Finished with a manganese or zinc phosphate coating that absorbs oil and inhibits rust.

  • Benefit: Provides superior protection against corrosion during storage and operation, and offers an excellent base for paint adhesion if required for site specifications.

Frequently Asked Questions (FAQ)

Q1: Is this a direct OEM replacement for my SANY excavator?
A: Yes. This DPW Drive Wheel is engineered to be a direct, bolt-on replacement for the original SANY component on both the SY1250 and SY1350 models. It matches the original specifications for dimensions, spline configuration, and performance.

Q2: What is the main advantage of a forged sprocket?
A: Forging creates a continuous grain flow that follows the contour of the sprocket, resulting in superior impact and fatigue strength. This makes the sprocket much more resistant to cracking and tooth breakage under the shock loads common in excavator operation, ensuring greater reliability and a longer service life.

Q3: Do you recommend replacing other undercarriage parts at the same time?
A: For the best results and to maximize the life of your investment, we highly recommend replacing worn undercarriage components as a matched set. Installing a new sprocket on a worn track chain (or vice versa) will lead to accelerated, premature wear on both components. Ask us about a complete undercarriage package.

Q4: What is your lead time and packaging for international orders?
A: Lead times depend on current order volume and stock. The Drive Wheel is securely packaged with anti-corrosion VCI paper and robust wooden crating to ensure it arrives in perfect condition, anywhere in the world. Contact us for a specific lead time and freight quote.
