Functions of the PC200-5 Excavator Sprocket
This Komatsu PC200-5 sprocket is durable, provides powerful torque transmission, and meshes seamlessly with the track chain. Designed specifically for Komatsu PC200-5 and its compatible models, it not only saves your maintenance costs, but also operates reliably in harsh excavation, mining and construction environments.
Robust Material Selection and Heat Treatment Process
Premium Alloy Steel with Core-Toughness
Each sprocket is made using high-grade alloy steels like 35SiMn or 40Mn2, known for their high tensile strength and fatigue resistance. These materials ensure the sprocket core remains tough and resilient, reducing the risk of cracking or deformation under impact loads.
Deep-Hardened Tooth Surface
The tooth flanks are induction-hardened to an HRC rating of 50–58, achieving a wear-resistant surface that withstands abrasive soil, gravel, and clay without losing shape. This enhances the service life of both sprockets and track chains.
Precision Manufacturing: Ensuring Perfect Fit and Performance
These steps are performed under strict quality controls to guarantee consistency and compatibility with Komatsu OEM specifications.
Tooth Rough Machining
The sprocket blank is machined on a CNC lathe or gear hobbing machine to form the basic tooth profile.
Inner Ring Installation & 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.

Rigorous Quality Control for Reliable Field Performance
Every Komatsu sprocket undergoes strict inspection during and after production. We use hardness testing, runout tests, and surface profile verification to ensure every unit meets or exceeds OEM specifications. These measures reduce downtime and ensure long-term reliability in rugged environments.
Application Scenarios for PC200 Series Sprocket
PC200 sprockets are ideal for the following work conditions:
Quarrying and surface mining operations
Foundation excavation and rock demolition
Earthmoving and large-scale infrastructure construction
With high torque resistance and reliable power transmission, our sprockets help excavators maintain traction and balance on tough ground.
Maintenance Tips for Longer Service Life
To keep your sprocket performing at its best:
- Inspect teeth for abnormal wear or cracking every 500–800 working hours.
- Ensure track tension is within the recommended range to prevent tooth damage.
- Replace the sprocket and chain as a matched set to avoid uneven wear.
- Lubricate hardware connections to prevent rust and bolt loosening.
Installation and Maintenance Best Practices
Proper installation and maintenance are key to maximizing sprocket life:
- Clean the hub area before installation
- Ensure correct bolt torque to avoid misalignment
- Check chain tension periodically
- Replace worn track links in time to avoid premature sprocket damage
Following these guidelines helps avoid excessive noise, uneven wear, or tooth skipping during operation.
