Dingtai manufactures replacement Samsung excavator sprockets that engage track chain pins and transfer drive torque to move the undercarriage.
We operate factory-direct, supplying Samsung-compatible sprockets with full OEM manufacturing services for dealers, distributors, and equipment fleets worldwide.
Precision-hardened teeth and tough steel resist wear and deformation, preventing track slippage, premature chain wear, and costly excavator downtime.
With 20+ years of experience, Dingtai holds ISO9001 and SGS certifications, ensuring every Samsung sprocket meets verified quality standards.
We use 35MnB steel and deep induction hardening to create a hard tooth surface with a tough, impact-resistant core.
Core Selling Points
- Premium 35MnB Material: Samsung sprockets are forged from 35MnB steel for high tensile strength and resistance to tooth breakage under heavy travel loads.
- Deep Quenching/Heat Treatment: Deep induction quenching produces a hard tooth surface while retaining core toughness, extending sprocket life in abrasive conditions.
- Global Brand Compatibility: Sprockets are machined to match original Samsung bolt patterns and pitch dimensions for accurate component fit.
- 100% QC Inspection: Every sprocket passes dimensional checks and hardness testing before shipment, ensuring consistent replacement-part quality.
Our catalog of Samsung Sprockets includes various specifications, fully compatible with Samsung excavators and bulldozers.

Technical Features
Each sprocket undergoes induction hardening to produce a wear-resistant tooth surface and a shock-absorbing core, balancing hardness with impact toughness.
Precision CNC machining of bolt holes and pilot bore maintains concentric rotation, preventing uneven tooth loading and premature track chain wear.
Select models use segmented tooth rings, allowing quick replacement of worn teeth without complete hub disassembly, reducing maintenance downtime.
Applications
- Mining: High-abrasion haul roads and continuous heavy traction loads.
- Quarrying: Rock impacts, dust, and demanding undercarriage conditions.
- Road Construction: Frequent travel cycles and mixed terrain operations.
- Demolition: High-impact work over uneven, debris-covered ground.
Frequently Asked Questions
What is your MOQ for Samsung sprockets?
Our MOQ is typically 1–4 pieces for stock specifications. Custom production quantities depend on your exact part number or drawing.
How long is delivery?
Stock items ship within 7–10 days. Custom-manufactured sprockets generally take 25–35 days depending on order quantity and specifications.
What is the heat treatment depth?
Tooth surface induction hardening is typically 6–10 mm deep, achieving HRC 50–55 for wear resistance.
Do you offer warranty?
Yes, we provide a 12-month warranty against manufacturing defects under normal operating conditions.
How do I match my Samsung part number?
Send your existing part number, drawing, or sample. Our engineers verify dimensions, bolt pattern, and tooth profile before quotation.
Can you produce OEM custom sprockets?
Yes, we manufacture from drawings or samples and follow OEM specifications for dimensions, materials, and heat treatment.
Maintenance Guide
- Inspection: Check sprocket teeth for sharpening, hooking, or missing segments every 250–500 operating hours.
- Installation: Clean the hub and mating surface, then torque bolts to OEM specification in a cross pattern.
- Replacement: Replace the sprocket together with the track chain if tooth wear exceeds 25% of the original profile.
- Lubrication: Maintain correct final drive oil levels to protect the sprocket mounting hub from excessive heat.
