We manufacture Liebherr bulldozer sprocket segments, bolt-on drive components that transfer engine torque from final drive to the track chain.
Factory-direct service provides complete OEM manufacturing, custom machining, and flexible production for global equipment distributors and end users.
Precision segments resist impact loads, reduce sprocket wear, and prevent track slippage, minimizing costly dozer downtime in abrasive working conditions.
Over 20 years of undercarriage manufacturing experience backed by ISO9001 and SGS certification ensures consistent metallurgy, hardness, and dimensional accuracy.
We use 35MnB steel and deep induction hardening to produce a hard wear surface with a tough shock-resistant core.
Core Selling Points
- Premium 35MnB Material: Forged from 35MnB steel for excellent hardenability and impact resistance under heavy bulldozer loads.
- Deep Quenching/Heat Treatment: Induction hardened to HRC 50-56 with deep case depth to extend service life against abrasive wear.
- OEM Capabilities: Manufactured to original Liebherr drawings or samples, ensuring exact bolt pattern and pitch diameter.
- ISO9001/SGS Certified: Each production batch is certified and dimensionally inspected to meet international quality standards.

Delivery & Logistics
Factory-direct pricing with flexible MOQ and reliable sea, rail, or air freight to major US ports. Standard lead time is 25-45 days after order confirmation.
Technical Features
The bolt-on segment design allows replacement without removing the entire sprocket hub, reducing service downtime and maintenance labor.
Deep induction hardening creates a martensitic wear layer on tooth flanks while the core remains ductile to absorb shock loads.
CNC-machined bolt holes and indexing ensure exact fit with Liebherr hubs, preventing stress concentration and premature bolt failure.
Applications
- Mining and quarrying
- Road construction
- Land clearing and forestry
- Landfill and waste handling
- Heavy civil earthmoving
Frequently Asked Questions
Q: What is the minimum order quantity for Liebherr bulldozer segments?
A: We accept low MOQ from 4 to 8 pieces per part number, depending on existing tooling and production schedule.
Q: What is the standard delivery time?
A: Standard lead time is 25-45 days for OEM production, plus 15-30 days shipping to US ports depending on freight mode.
Q: How deep is the heat treatment hardening?
A: Induction hardening depth ranges from 4-8 mm on tooth flanks, depending on segment size and original Liebherr specification.
Q: What warranty do you provide?
A: We provide a 12-month or 1,500-hour warranty against material defects and manufacturing workmanship under normal operating conditions.
Q: Can you match original Liebherr part numbers?
A: Yes. Send your Liebherr part number, machine serial number, or dimensional drawing; we cross-reference and confirm fitment before production.
Q: Do you manufacture custom or obsolete segment dimensions?
A: Yes. We reverse engineer from samples or drawings for discontinued models and custom track drive conversions.
Q: How do I confirm the correct segment for my dozer model?
A: Check the sprocket hub bolt pattern, tooth count, pitch diameter, and segment thickness; our engineers verify all dimensions before quotation.
Maintenance Guide
- Check segment bolt torque every 250 operating hours; re-torque to OEM specifications if any loosening is detected.
- Inspect tooth profiles for sharpening, hooking, or cracking; replace segments before excessive wear damages the track bushings.
- Clean hub and segment mating surfaces to remove rust, debris, and old sealant before installation.
- Install bolts in a star pattern and tighten evenly to prevent stress distortion of the segment ring.
- Replace segments in complete sets to maintain equal drive force and avoid uneven track wear.
