Dingtai manufactures aftermarket Liebherr track rollers. These rollers support the machine’s weight and guide track chains through harsh undercarriage conditions.
We supply factory-direct with comprehensive OEM manufacturing services for global distributors, dealers, and equipment owners requiring dependable replacements.
Our track rollers prevent premature undercarriage failure. Hardened materials and exact tolerances resist wear, reduce downtime, and stop costly breakage.
With over 20 years’ experience, Dingtai operates under ISO9001 and SGS quality systems, delivering consistent components for heavy machinery applications.
We use 35MnB steel and deep quenching technology to produce high surface hardness, improving load capacity and extending service life.
Core Selling Points
- Premium 35MnB Material: Rollers are forged from 35MnB steel for high fatigue strength and impact resistance in demanding Liebherr applications.
- Deep Quenching/Heat Treatment: Deep quenching creates a hardened layer that resists surface wear and deformation under continuous heavy loads, extending replacement intervals.
- Global Brand Compatibility: Manufactured to match Liebherr OEM dimensions, ensuring direct replacement across popular excavator and bulldozer series without modification.
- 100% QC Inspection: Every roller undergoes dimensional checks, hardness testing, and seal verification before shipment, reducing field failure and warranty claims.
Product Range
Our catalog of Liebherr track rollers includes various specifications, fully compatible with Liebherr excavators and bulldozers.

Technical Features
Liebherr track rollers use a sealed, lifetime-lubricated design. Floating seals retain oil and block abrasive sand, water, and dust from entering the roller cavity.
Bimetal bushings and precision-ground shafts reduce internal friction and heat, preventing galling and extending service life under continuous high-load operation.
The outer shell receives deep quenching to produce a hard wear surface while the core remains tough, balancing wear resistance with impact strength.
Applications
- Mining
- Quarrying
- Heavy Civil Construction
- Demolition
- Forestry
Frequently Asked Questions
- 1. What is the minimum order quantity for Liebherr track rollers?
- OEM trial orders start from 1 piece. Bulk pricing is available from 10–20 pieces, depending on roller model.
- 2. What is the delivery time?
- Standard models ship in 15–25 days after deposit. Custom OEM production takes 30–45 days depending on quantity and specifications.
- 3. How deep is the heat treatment?
- Surface hardening reaches HRC 48–56 with effective depth typically 5–10 mm, depending on roller size and material specification.
- 4. What warranty do you provide?
- We provide 12 months or 2,000 working hours from shipment, covering manufacturing defects in material and heat treatment.
- 5. Can you match my Liebherr part number?
- Yes. Send the OEM part number or drawing, and we will confirm interchangeability, dimensions, and technical specifications.
- 6. Are these track rollers genuine Liebherr parts?
- No. They are aftermarket replacement parts manufactured to OEM specifications and compatible dimensions.
- 7. Do you supply samples?
- Yes. Sample orders are available for first-time buyers to verify fit, hardness, and sealing performance before bulk orders.
Maintenance Guide
- Inspect roller tread and flanges every 250 service hours. Look for cracks, uneven wear, oil leaks, or missing bolts.
- Check track sag and tension. Incorrect tension accelerates roller and rail wear, increasing the risk of flange failure.
- Clean debris from the undercarriage before installation. Dirt trapped between roller and frame causes misalignment and premature seal damage.
- Torque mounting bolts to OEM specifications. Under-tightening causes movement; over-tightening cracks the roller body or frame.
- Replace rollers as sets when flange wear exceeds 20% of original height. Mixing new and worn rollers creates uneven load distribution.
