Dingtai manufactures heavy-duty John Deere sprockets. These forged steel components transfer track drive power and guide track links through the undercarriage.
We operate factory-direct with full OEM manufacturing services. Global clients receive custom sprocket production, precise CNC machining, and rigid quality control.
Worn sprockets accelerate track pin and bushing wear, causing unplanned downtime. Our hardened tooth profiles resist abrasive wear and reduce replacement frequency.
Dingtai has over 20 years of undercarriage manufacturing experience. ISO9001 and SGS certifications verify our process stability, material traceability, and product consistency.
We use premium 35MnB alloy steel and deep induction quenching. This technology creates a hard wear surface while maintaining a tough, impact-resistant core.
Core Selling Points
- Premium 35MnB Material: Forged high-grade 35MnB steel provides superior tensile strength and fatigue resistance compared with standard cast sprockets.
- Deep Quenching/Heat Treatment: Tooth flanks are induction hardened to HRC 50-55 with deep case depth, extending service life under heavy impact.
- Global Brand Compatibility: Precision dimensions match John Deere OEM part numbers and aftermarket undercarriage systems for excavators and dozers.
- 100% QC Inspection: Every sprocket passes dimensional inspection, hardness testing, and tooth profile verification before shipment, reducing field failures.
Our catalog of John Deere Sprockets includes various specifications, fully compatible with John Deere excavators and bulldozers.

Technical Features
Forged 35MnB steel gives high tensile strength and resists tooth fracture under shock loads in rocky or uneven terrain.
Deep induction hardening creates a wear-resistant tooth flank while preserving a ductile core, reducing brittle failure risk.
CNC-machined tooth pitch ensures smooth engagement with track links, minimizing vibration, uneven wear, and drive motor stress.
Applications
- Mining: haul road and pit operations with abrasive rock.
- Road Construction: dozer and excavator site preparation.
- Quarrying: track machines handling blasted stone and high-impact loads.
- Demolition: debris-cluttered jobsites requiring impact-resistant sprockets.
- Forestry: soft ground and stump terrain under constant track load.
Frequently Asked Questions
What is the minimum order quantity for John Deere sprockets?
Stock items can be ordered from 1 piece. OEM production generally starts at 4-8 pieces, depending on the model.
How long is production and delivery?
Stock sprockets ship within 7-10 days. Custom-manufactured sprockets require 25-35 days plus transit time.
What case depth do you achieve?
Induction hardening typically reaches 6-10 mm on tooth flanks, with hardness controlled to HRC 50-55.
What is the warranty policy?
We provide 12 months or 2,000 operating hours against manufacturing defects under normal working conditions.
Can you match John Deere OEM part numbers?
Yes. Send the OEM part number or drawing; we confirm exact interchange, pitch, and bolt pattern before quotation.
Are your sprockets compatible with aftermarket John Deere undercarriage?
Yes, they are engineered to standard John Deere pitch and mounting dimensions for excavators and dozers.
Maintenance Guide
- Inspect sprocket teeth every 250 operating hours for sharp, hooked, or chipped profiles.
- Replace when tooth wear exceeds 25% or track pin elongation exceeds 3% of pitch.
- Clean mounting surfaces and torque bolts to John Deere OEM specifications during installation.
- Maintain correct track sag; over-tight track increases sprocket and bushing wear.
- Replace sprocket and track chains as matched sets to ensure even load distribution.
