Top Description
We manufacture Komatsu sprockets, the critical drive component that transfers engine power to the track chain, ensuring positive traction.
Factory-direct status means no intermediaries. We deliver comprehensive OEM manufacturing services, matching exact dimensional requirements for global distributors.
Our sprockets prevent costly track skipping and premature bushing wear, directly reducing unplanned downtime on demanding job sites.
With 20+ years of heavy machinery manufacturing, our ISO9001 and SGS-certified systems guarantee repeatable, documented quality.
Each sprocket is forged from 35MnB alloy steel and deep induction hardened to deliver a long-life wear surface and core toughness.
Core Selling Points
- Premium 35MnB Material – Forged from high-grade 35MnB steel, this material provides superior tensile strength and impact resistance compared to standard carbon steels.
- Deep Quenching/Heat Treatment – Induction hardening achieves HRC 48-55 with effective case depth up to 8mm, creating a durable wear layer that extends service life.
- Global Brand Compatibility – Precision-manufactured to interchange seamlessly with a wide range of Komatsu excavator and bulldozer models without modification.
- ISO9001/SGS Certified – Every production batch is controlled under ISO9001 and verified by SGS, ensuring full traceability and consistent OEM-grade output.

Block B: Technical Features
The sprocket is forged from 35MnB alloy steel, then induction hardened. This process creates a high-hardness surface (HRC 48-55) while retaining a tough, shock-resistant core.
Precision tooth profile grinding ensures exact pitch diameter match with the track chain, which reduces vibration, minimizes bushing wear, and extends undercarriage life.
Block C: Applications
- Open-pit Mining
- Heavy Earthmoving and Road Construction
- Quarrying and Aggregate Handling
- Forestry Machinery
- Demolition and Scrap Recycling
Block D: Frequently Asked Questions (FAQ)
- What is the minimum order quantity (MOQ)?
- Trial orders start at 1 piece. Standard production MOQ is typically 20-50 pieces, depending on the specific model.
- How long is the delivery time?
- Sample orders ship within 3-5 days. Regular production orders usually deliver within 25-30 days after deposit confirmation.
- How deep is the induction hardening on the sprocket teeth?
- Effective case depth ranges from 4mm to 8mm, depending on the part number and tooth geometry, ensuring extended wear life.
- What is your warranty policy?
- We provide a 12-month warranty against manufacturing defects under normal operating conditions. Wear parts are excluded from breakage claims.
- Can you match my Komatsu part number exactly?
- Yes. Send us the OEM part number or a drawing, and we will produce an exact interchange sprocket that fits without modification.
Block E: Maintenance Guide
- Inspect tooth profile regularly. Replace sprockets when teeth become pointed or sharply hooked to prevent chain damage.
- Ensure track tension is correct. Over-tension accelerates sprocket and bushing wear; under-tension risks derailment.
- Re-torque mounting bolts after the first 50 operating hours, then every 250 hours to maintain secure attachment.
