We manufacture Case sprockets as final drive components that transfer track drive force and engage track chain bushings to propel excavators and dozers.
Factory-direct production provides comprehensive OEM manufacturing, custom machining, and private labeling for global equipment distributors and rental fleets.
Our sprockets prevent costly downtime caused by premature tooth wear, track slippage, and misalignment in abrasive working conditions.
Dingtai has over 20 years of undercarriage engineering experience, with ISO9001 and SGS certified processes ensuring consistent quality and traceability.
Using forged 35MnB steel and deep induction-hardened teeth, each sprocket delivers high wear resistance and impact strength under heavy loads.
Core Selling Points
- Premium 35MnB Material: Forged from high-grade 35MnB steel, our sprockets provide excellent impact toughness and resistance to deformation under severe load.
- Deep Quenching/Heat Treatment: Tooth flanks and roots are induction hardened to HRC 50-55, creating a hard wear surface over a ductile core.
- Global Brand Compatibility: Direct replacement for Case CX/CXB excavators and dozers, matching OEM pitch, bolt circle, and center bore specifications.
- 100% QC Inspection: Every sprocket undergoes dimensional checks, hardness testing, and surface finish verification before packing and shipment.
Our catalog of Case sprockets includes various specifications, fully compatible with Case excavators and bulldozers.

Technical Features
Sprocket teeth engage track chain bushings; precise tooth profiles distribute load evenly and reduce premature pin and bushing wear.
Induction hardening creates a martensitic tooth surface while retaining a tough core, balancing abrasion resistance with impact strength.
CNC-machined bolt holes and pilot bores ensure exact mounting alignment, reducing stress on final drives and track frames.
Applications
- Mining: heavy rock excavation, haul road maintenance, and material loading
- Road Construction: site preparation, trenching, and slope stabilization
- Quarrying: aggregate extraction, bench clearing, and stockpile management
- Demolition: high-impact material processing and structure dismantling
Frequently Asked Questions
What is the MOQ for Case sprockets?
Standard MOQ is 4 pieces per part number; sample orders are available for first-time inspection.
What is the typical delivery time?
Standard production takes 25-35 days; stock items ship within 7 days.
How deep is the heat treatment?
Tooth surface is induction hardened to HRC 50-55, with effective case depth typically 6-10 mm.
What warranty do you provide?
12 months or 2,000 working hours for material and manufacturing defects, whichever comes first.
Can you match my Case part number?
Yes, provide your OEM part number or drawing; we cross-reference dimensions and tooth profile to supply exact replacement.
Do you offer samples?
Yes, sample orders are accepted for evaluation before bulk purchasing.
Maintenance Guide
- Inspect: Check teeth for sharp points or hooked wear; replace when tooth tip width is worn 20% or more.
- Install: Clean hub and mating surfaces; torque bolts to OEM specifications in a crossed pattern.
- Align: Confirm sprocket and idler alignment with track frame to prevent uneven wear.
- Lubricate: Maintain clean final drive oil; seal leaks cause overheating and bearing failure.
- Replace: Pair new sprockets with chains if wear is advanced to avoid premature wear.
