Kinton Parts is trusted by professionals worldwide for delivering high-quality parts for excavators, bulldozers, and other construction machinery—with guaranteed performance and durability.
The Komatsu PC60-5 drive sprocket is engineered to deliver consistent drive performance and long-term durability for small-to-medium-sized excavators. As a key undercarriage component, it transmits engine torque to the track system, ensuring your machine maintains optimal traction and control in digging, trenching, and grading operations. Its compact design is matched with rugged construction to handle tough site conditions without failure.
Premium Materials & Heat-Treated for Extended Life
Each sprocket is made from high-grade forged steel, typically 35Mn or 40Mn2, selected for its high tensile strength and resistance to impact and wear. The core is treated for toughness while the teeth undergo surface hardening to reach HRC 52–58. This dual-layer hardness structure ensures both flexibility and wear resistance, allowing for prolonged usage in sand, gravel, clay, and mixed soil environments.
Advanced Manufacturing with Precision Machining
To ensure exact fit and performance, the PC60-5 sprocket is produced using CNC and gear hobbing technologies.
- Tooth profiles are machined with high precision to match track links
- Bolt holes and lubrication channels are drilled with tight tolerances
- Post-heat-treatment grinding ensures smooth gear engagement and minimized chain wear
A rust-resistant industrial coating (black, yellow, or custom colors) enhances corrosion resistance and maintains a professional finish
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.
Thorough Quality Control
All sprockets undergo dimensional inspection, hardness testing, and fitment verification before shipment. Our QA process ensures each sprocket performs to OEM standards for reliability and interchangeability with original undercarriage systems.
