Top Description
We manufacture Volvo track link assemblies—the load-bearing link chain that transfers machine weight, drive torque, and traction across the undercarriage.
As factory-direct China manufacturer, Dingtai provides complete OEM production, machining, heat treatment, and assembly services for global equipment suppliers.
Our track link assemblies resist elongation, cracking, and rapid rail wear—helping fleets avoid unplanned downtime and high undercarriage replacement costs.
Dingtai has 20+ years of undercarriage manufacturing experience and holds ISO9001 and SGS certifications, ensuring consistent quality for procurement professionals.
We forge links from 35MnB steel and apply induction hardening to rail surfaces, producing high hardness and long service life.
Core Selling Points
- Premium 35MnB Material: Track links are forged from 35MnB alloy steel, offering high tensile strength and crack resistance under heavy impact loads.
- Deep Quenching/Heat Treatment: Rail surfaces receive induction hardening to HRC 50–56, while pins and bushings are through hardened for wear resistance.
- Global Brand Compatibility: Direct replacement assemblies match original Volvo pitch, link height, and pin diameter for seamless installation on EC series excavators.
- 100% QC Inspection: Every assembly is checked for dimensional accuracy, hardness, and surface defects before packing, reducing warranty claims.
Our catalog of Volvo Track Link Assembly includes various specifications, fully compatible with Volvo excavators and tracked equipment.

Technical Features
Track links are precision forged from 35MnB steel and induction hardened on rail surfaces to HRC 50–56, increasing fatigue resistance.
Pins and bushings are through hardened and matched with controlled interference fit, preventing premature pitch elongation and pin breakage.
Optional lubricated track links use floating seals to retain oil and block abrasive soil, reducing internal wear in demanding conditions.
Applications
- Mining: Track link assemblies handle abrasive overburden and high-impact haul roads.
- Road Construction: Provide stable traction for excavators on asphalt and aggregate surfaces.
- Quarrying: Resist rock penetration, spalling, and heavy torsional loads.
- Demolition: Withstand debris impact and frequent pivot maneuvering.
Frequently Asked Questions
Q: What is the MOQ for Volvo track link assemblies?
A: MOQ is 2 pieces per part number. Trial orders are accepted for first-time buyers.
Q: What is the delivery time?
A: Standard production takes 15–30 days after deposit confirmation, depending on order quantity and customization.
Q: What heat treatment do the track links receive?
A: Rail surfaces are induction hardened to HRC 50–56, with case depth 4–8 mm for wear resistance.
Q: What is the warranty policy?
A: 12 months or 2,000 operating hours under normal working conditions. Cracked or broken links are replaced after inspection.
Q: How do I match my Volvo part number?
A: Send your OEM part number, machine model, or a drawing. Our engineers cross-check pitch, pin diameter, and link height.
Q: Can you produce non-OEM or custom track link assemblies?
A: Yes. We manufacture to supplied drawings, including custom dimensions, hardness specifications, and branding.
Q: Are the assemblies compatible with older Volvo EC models?
A: Yes, we support legacy series such as EC210B, EC240B, EC290B, EC360B, and EC460B with matched pitch dimensions.
Maintenance Guide
- Inspect link rail height and pin/bushing clearance every 250 operating hours to detect early wear.
- Maintain correct track sag according to the Volvo operator manual; excessive tension accelerates link and pin wear.
- Replace track link assemblies when link rail height is worn beyond 20% or pitch elongation exceeds 3%.
- Clean and inspect shoe bolt holes before assembly; torque bolts to OEM specifications to prevent loosening.
