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 PC30 sprocket is designed to deliver stable and efficient power transmission for compact excavators working in tight spaces and light construction jobs. Despite its smaller size, it plays a crucial role in ensuring consistent torque transfer and track engagement. The tooth profile and bolt patterns are tailored for perfect alignment with the undercarriage system of the PC30 series.
Durable Material and Enhanced Heat Treatment
This sprocket is manufactured from high-strength alloy steel such as 40Mn or 35MnB, selected for its balance of toughness and wear resistance. The forging process ensures a dense internal structure, while advanced heat treatment techniques—quenching and tempering—raise the surface hardness to HRC 52-58. This gives the sprocket exceptional resistance to wear and fatigue even in continuous or abrasive working conditions.
Manufacturing Process and Surface Finishing
Each PC30 sprocket is produced with strict precision. After rough machining, the tooth profile is shaped using gear hobbing machines. The inner bore is CNC-machined to ensure proper concentricity. Drilling of mounting and lubrication holes is followed by post-hardening surface grinding to remove burrs and ensure smooth engagement. Finally, the sprocket receives a protective industrial-grade paint coating that prevents corrosion and delivers a clean appearance.
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.
Quality Inspection and OEM Compliance
Every batch of PC30 sprockets is inspected for critical dimensions, surface flatness, and hardness consistency. The tooth pitch is precisely controlled to minimize chain wear and vibration. These products meet or exceed OEM standards and undergo compatibility testing with track links and frames to guarantee proper installation.
