Our Volvo sprockets are precision-manufactured undercarriage drive components that transfer engine torque to the track chain for reliable excavator mobility.
We provide factory-direct sales with full OEM service, customizing sprocket dimensions, bolt patterns, and tooth profiles for global equipment fleets.
These sprockets resist premature tooth wear and deformation, preventing track slippage and unscheduled downtime on demanding job sites.
With over 20 years of undercarriage manufacturing experience, Dingtai holds ISO9001 and SGS certifications, ensuring consistent quality for procurement professionals.
Each sprocket uses 35MnB alloy steel and deep medium-frequency quenching, achieving high surface hardness without sacrificing core toughness.
Core Selling Points
- Global Brand Compatibility: Engineered for direct interchange with Volvo EC series excavators; no modification needed for exact mounting and pitch diameter.
- Premium 35MnB Material: Forged from 35MnB alloy steel to deliver high tensile strength and impact resistance under heavy digging and travel loads.
- Deep Quenching/Heat Treatment: Medium-frequency induction hardening creates a deep hardened layer, extending tooth life and reducing replacement frequency.
- 100% QC Inspection: Every sprocket undergoes dimensional, hardness, and ultrasonic inspection before shipment, ensuring zero-defect supply for critical undercarriage systems.
Our catalog of Volvo sprockets includes various specifications, fully compatible with Volvo EC series excavators and tracked carriers.

Technical Features
The sprocket rim is forged from 35MnB alloy steel, then induction-hardened to HRC 52–58 on wear surfaces, balancing hardness with impact toughness.
Precision CNC-machined tooth profiles ensure accurate chain engagement, distributing load evenly and reducing wear on track links.
Bolt holes and pilot bores are machined to OEM tolerances, guaranteeing correct alignment and torque transfer to the final drive.
Applications
- Mining operations with abrasive rock and high-impact digging.
- Road construction and site preparation under continuous track travel.
- Quarrying and aggregate handling with heavy bucket loads.
- Demolition and recycling yards with mixed debris.
- Heavy civil and infrastructure projects requiring long undercarriage life.

Maintenance Guide
- Inspect sprocket teeth for sharp points or hooking before installation; install with new or matching-wear track chain components.
- Torque mounting bolts to OEM specifications and re-check after 50 operating hours to prevent bolt loosening.
- Monitor tooth wear regularly; replace sprocket when tooth tips become knife-edged or track pitch mismatch causes popping.
- Keep undercarriage clean and adjust track tension to reduce uneven sprocket and track link wear.
- For mixed wear applications, replace sprocket and track chain together to maximize service life and avoid accelerated wear.
