Product Function & Structural Advantages of SK60 Sprocket
As a key component in the undercarriage system, the sprocket engages with the track chain to transmit torque from the final drive, propelling the excavator forward or backward. Our SK60 sprockets are engineered to ensure optimal tooth-to-link engagement, reducing slippage and minimizing vibration. The structure is optimized to resist stress concentration, improving durability under frequent directional shifts and rough terrain.
Materials and Heat Treatment for Long-Lasting Performance
We use premium-grade 35MnB or 50Mn steel to achieve a balance of hardness and toughness. Each sprocket undergoes precision forging and CNC machining, followed by surface hardening through advanced quenching techniques.
This ensures:
- Tooth surface hardness reaches HRC 52-58
- Deep wear layer for long life
- Excellent impact resistance during heavy-duty excavation
Manufacturing Process for Precision Fit
Each sprocket is manufactured through a rigorous workflow to ensure dimensional accuracy and performance:
Tooth Rough Machining
The sprocket blank is machined on a CNC lathe or gear hobbing machine to form the basic tooth profile.
Inner Ring Precision Machining
The inner ring is inserted and the entire part is precisely machined to ensure concentricity and dimensional accuracy.
Drilling
Mounting and lubrication holes are drilled to meet the installation and functional requirements.
Tooth Grinding & Finishing
After heat treatment, the sprocket teeth are ground or polished to remove burrs and ensure smooth engagement.
Surface Cleaning
The sprocket undergoes surface cleaning, removing scale and residue, preparing it for surface treatment.
Painting & Final Coating
The sprocket is coated with durable industrial paint (available in various colors), providing corrosion resistance and a clean, professional appearance.
This precise control at each stage guarantees compatibility, balance, and durability.
