Track Roller Performance for Sunward SWE66
The SWE66 track roller is a critical undercarriage component responsible for supporting the excavator’s weight and ensuring stable track movement. Designed for compact and mid-range excavators like the Sunward SWE66, this roller provides excellent load distribution and shock resistance, ideal for small construction and utility jobs.
Steel Composition and Heat Treatment Advantages
To ensure maximum wear resistance, our SWE66 rollers are made using 45# carbon steel for the shell and 40Cr/42CrMo alloy steel for the bushing. The rollers undergo precise machining and surface heat treatment, achieving HRC 52–58 hardness for long-lasting durability in demanding terrain.
How We Manufacture the SWE66 Track Roller ?
Each SWE66 track roller is produced with precision and durability in mind. The process includes:
Heat Treatment
The roller body and shaft undergo high-frequency quenching and tempering to achieve a surface hardness of HRC 52–58, enhancing wear resistance and fatigue strength for long-term use in rough terrains.
Machining Process
CNC machining ensures precision on all critical surfaces, including shaft ends, bore diameters, and seal housings. This guarantees a perfect fit, concentric rotation, and smooth installation onto the undercarriage.
Assembly
All components—including shaft, seals, bushings, and O-rings—are assembled in a dust-free environment to prevent contamination and ensure optimal sealing performance under pressure and vibration.
Running Test
Each roller is subjected to a dynamic rotation test to verify concentricity, smoothness, and internal lubrication flow. Any noise, resistance, or oil leakage is checked and corrected before approval.
Paint Spraying
The surface is coated with anti-corrosion industrial paint, often in black or yellow, to protect the roller from rust and harsh environmental exposure during storage and field use.
Packing
Finished rollers are wrapped in anti-rust film and packed into pallets or fumigated wooden crates. Each package is labeled with model, size, and quantity for easy handling and identification.
