SANY SY1250 SY1350H Drive Wheel / Final Drive Sprocket Assembly DPW Parts Complete Buying Guide for Heavy Machinery Users

When construction equipment owners and distributors search for reliable and durable SANY SY1250 and SY1350H drive wheel assemblies, one of the most frequently requested components is the Final Drive Sprocket Assembly (DPW Parts). These parts play a crucial role in the performance, stability, and long-term operating efficiency of large excavators. In this comprehensive guide, we will walk through what buyers actually want to know: compatibility, structure, durability, sourcing options, and why choosing a professional China manufacturer can significantly reduce downtime and cost.

What Is the Drive Wheel / Final Drive Sprocket Assembly?

For heavy-duty excavators like the SANY SY1250 and SANY SY1350H, the final drive sprocket assembly is the key component that delivers power from the travel motor to the track chain. It transfers torque efficiently, ensures smooth movement, and maintains stability on rough terrains such as mines, quarries, and large construction sites.

To put it simply:
No high-quality sprocket → no stable travel performance.
It’s as essential as it sounds.

This is why global buyers from rental fleets to construction contractors—care deeply about sprocket accuracy, tooth hardness, and long-term durability.

Key Features of SANY SY1250 / SY1350H Drive Wheel Assembly (DPW Parts)

Although specifications vary by batch and OEM/ODM requirements, high-performance sprocket assemblies generally include these features:

1. High-Strength Alloy Steel Structure

A durable sprocket is typically manufactured using premium materials such as 40Cr or 35Mn, which provide outstanding strength and fatigue resistance. This ensures the sprocket can withstand constant high-load operations.

2. Advanced Heat Treatment for Long Service Life

Standard processes include:

• Quenching and tempering

• Surface induction hardening

• Carburizing or nitriding (depending on model)

These technologies enhance tooth hardness, improve wear resistance, and reduce deformation critical for maintaining proper engagement with the track links.

3. Precision Machining for Perfect Fit

Accurate CNC machining ensures:

• Smooth power transmission

• Reduced vibration

• Lower wear on the chain links and bushings

A precise fit helps extend the total undercarriage lifespan.

4. Strong Compatibility with SANY Heavy Excavators

Designed to perfectly match:

• SANY SY1250

• SANY SY1350H

• Additional large SANY excavator series (depending on customization)

This ensures easy installation and seamless replacement during maintenance.

Applications: Where Are These Sprocket Assemblies Used?

Large-scale excavators equipped with the SY1250 or SY1350H drive systems are typically used in:

• Mining operations

• Rock quarries

• Road and bridge construction

• Hydropower engineering

• Heavy material handling projects

For these demanding applications, the sprocket’s durability and impact resistance become especially important.

And honestly, when you're operating machinery that weighs over a hundred tons you definitely don’t want to compromise on undercarriage parts.
