Kinton Parts is trusted by professionals worldwide for delivering high-quality parts for excavators, bulldozers, and other construction machinery—with guaranteed performance and durability.
Our SH220 sprockets are manufactured using high-strength alloy steel, commonly 40Mn2 or 35SiMn, known for its excellent toughness and wear resistance. Through high-frequency induction hardening, the tooth surface reaches a hardness level of HRC 50–58, enabling it to resist abrasion and impact during continuous heavy-duty operation.
This heat-treated structure combines a hardened outer layer for wear resistance with a tough core that absorbs shock loads, ensuring a balance of durability and resilience essential for excavators working in variable ground conditions.
Precision Manufacturing Process of SH220 Sprocket
Every SH220 sprocket undergoes a multi-step precision machining process to guarantee dimensional accuracy and smooth engagement with the track chain. The process includes:
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.
This workflow ensures each sprocket meets or exceeds OEM specifications, delivering consistent quality and reliable performance.
Perfect Fit for SH220 and Similar Sumitomo Excavators
This sprocket is engineered for:
Sumitomo SH220 / SH220LC
Compatible with SH210, SH240, and other Sumitomo models sharing identical hub dimensions and mounting hole patterns (please confirm before ordering)
We provide technical support and drawing verification if you’re unsure about compatibility.
Rigorous Quality Control for Reliable Field Performance
Every SH220 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 Versatility & Field-Proven Durability
The SH220 sprocket has proven performance in a wide range of operating environments:
- Earthworks and road foundation construction
- Pipeline trenching and utility excavation
- Demolition and recycling operations
- Light mining and quarrying applications
Its tooth geometry and hardened surfaces ensure smooth track movement, reduced vibration, and minimal wear even under demanding terrain conditions.
